Description

  The present invention relates to a telephone connected to a public telephone line network, a cordless telephone, a telephone having a facsimile device function or a facsimile function, and outputting a countermeasure sound for suppressing a nuisance call such as a silent telephone. The present invention relates to a telephone having a function. In particular, the present invention, in a telephone having a function for outputting a countermeasure sound for annoying calls, continues to output the countermeasure sounds for a certain period of time after on-hook so that the countermeasure sounds output functions effectively for the caller of unwanted calls. In addition, the present invention relates to a telephone set that re-captures a line after a predetermined time when a user performs an off-hook operation for a call.

  Conventionally, in offices and homes, in addition to fixed telephones such as subscriber telephones connected to a public telephone line network, cordless telephones composed of a main unit and a sub unit connected by a wireless communication function have been widely used. In recent years, telephones to which a facsimile apparatus can be connected, telephones having a facsimile function in the base unit, and cordless telephones are also widespread. In this specification, the term “phone” includes a cordless telephone equipment and a telephone having a facsimile function.

  Recently, the damage caused by incoming unwanted calls such as silent calls and mischievous calls to telephones has increased, and there is a sound that causes discomfort to the other party's telephone (calling side telephone) when such unwanted calls are received. There has also been proposed a means for preventing a nuisance call from being made again from the same caller by outputting (repulse sound: hereinafter referred to as a countermeasure sound).

  For example, the following Patent Document 1 (Japanese Patent Laid-Open No. 8-149202) discloses a telephone corresponding to an annoying telephone (outputting a repulse sound) as a “cordless telephone”. This cordless phone is designed to increase the effect of stuttering without sound, and when it is judged that the receiving user is a nuisance phone And an operation key for outputting a mischievous retreat sound, and when the user determines that it is a mischievous call, the operation key is pressed to start outputting a repelling sound to the other party, and a repulse sound is output while a busy sound is detected, When the other party hangs up the telephone and no longer hears the busy sound, the call is terminated and the apparatus returns to the standby state.

FIG. 9 is a flowchart showing an operation procedure when a nuisance call is received in the cordless telephone disclosed in Patent Document 1. As shown in FIG. 9, when a user receives a telephone call and determines that it is a mischievous telephone call during communication, the operation of S1 is performed by a key operation, and a mischievous retreat sound is sent to the line. Next, in S2, it is determined whether or not the cordless handset is on-charged. If it is on-charged, the process proceeds to step S3. Otherwise, the process proceeds to S4. In S3, the prank sound is output to the line and the loudspeaker, and the process proceeds to S5. In S4, the prank sound is output to the line and the cordless handset, and the process proceeds to S5. In S5, it is determined whether or not a busy sound is detected from the line. If a busy sound is detected, the process proceeds to S6, and if not, S2 is repeated. In S6, the telephone call is terminated and a standby state is entered.
JP-A-8-149202 (FIG. 1, FIG. 2, paragraph [0006])

  In the cordless telephone disclosed in the above-mentioned Patent Document 1, the transmission of the countermeasure sound is always continued even if it is on-hook while the countermeasure sound is being output. With such a configuration, the line remains connected unless the calling party who has made a call for mischief calls goes on-hook. For this reason, it is impossible to make a call when the user wants to immediately terminate the call with the other party for the purpose of the mischievous call and immediately call the other party. On the other hand, if the countermeasure sound is not transmitted for a certain period of time, the effect of threatening the destination for the mischievous call purpose or giving up the mischievous call is halved.

  The inventor of the present application has conducted various studies to solve the above problems, and as a result, when the side receiving the junk call or mischief call outputs a repulse sound, the countermeasure sound (repel It is conceived that the above-mentioned problem can be solved if the output is continued and the line is re-acquired after a predetermined time when the user performs an off-hook operation for a telephone call. The invention has been completed.

  That is, the present invention has an object to solve the above problems, and in a telephone having a function for outputting a countermeasure sound for a nuisance call, the countermeasure sound output can be effectively functioned for a nuisance caller, and Then, it is an object of the present invention to provide a telephone having an annoying phone countermeasure sound output function that can re-acquire a line after a predetermined time has elapsed when a user performs an off-hook operation for a telephone call.

  The invention according to claim 5 of the present application is the telephone set according to claim 1 or claim 2, wherein the telephone set includes means for storing at least a caller's telephone number and call arrival time as an incoming call history. When the number of consecutive incoming calls from the side telephone number exceeds a predetermined number, the measure selection detecting unit determines that the incoming call is a nuisance call.

  Further, in the invention according to claim 6 of the present application, in the telephone according to any one of claims 1 to 5, the user can select whether or not the predetermined time is arbitrarily set by the user, and The setting is made possible after the call starts.

  In the invention according to claim 1, the countermeasure selection detection unit determines that the incoming call is a nuisance call, and the line connection continuation processing unit elapses a predetermined time from the on-hook operation when the own phone is on-hook. The line connection is continued until the countermeasure sound output control unit continues to output the countermeasure sound. When the off-hook detection unit detects an off-hook, the line connection disconnection processing unit disconnects the line and connects the line after a predetermined time has elapsed.

  Therefore, even if the user makes an on-hook operation when receiving a nuisance call, the line connection is continued until a predetermined time has elapsed since the on-hook operation, and the countermeasure sound is output during that time, so the other party's telephone disconnects. Since the predetermined set time countermeasure sound output is continued until the nuisance call suppression effect by the countermeasure sound output can be improved. In addition, when the user goes off-hook for a call, the line is re-acquired after a certain period of time, so if it is determined that the call is a nuisance call, a countermeasure sound can be output and the police can be notified.

  In the invention according to claim 2, the countermeasure selection detection unit determines that the incoming call is a nuisance call, and the line connection continuation processing unit, when the own phone is on-hooked, performs a predetermined time from the on-hook operation. The line connection is continued until the time elapses, during which the countermeasure sound output control unit continues the countermeasure sound output. When the off-hook detection unit detects off-hook, the line connection disconnection processing unit disconnects the line after continuing the line connection and countermeasure sound output for a predetermined time, and connects the line after a predetermined time has elapsed.

  Therefore, even if the user makes an on-hook operation when receiving a nuisance call, the line connection is continued until a predetermined time has elapsed since the on-hook operation, and the countermeasure sound is output during that time, so the other party's telephone disconnects. Since the predetermined set time countermeasure sound output is continued until the nuisance call suppression effect by the countermeasure sound output can be improved. Further, when the user goes off-hook for a call, the countermeasure sound output is continued until a predetermined time elapses, and then the line is recaptured. Therefore, it is possible to improve the nuisance call suppression effect by the countermeasure sound output. In addition, when it is determined that the call is a nuisance call, it is possible to report to the police or the like after outputting a countermeasure sound.

  According to a third aspect of the present invention, the telephone set according to the first or second aspect further comprises means for measuring a silent period during a call, and when the silent period exceeds a certain time, the countermeasure selection detection is performed. It is determined that the incoming call is a nuisance call. Therefore, when the silent period exceeds a certain time, it is determined that the call is a nuisance call, and the process of outputting the countermeasure sound can be performed.

  According to a fourth aspect of the present invention, in the telephone set according to the first or second aspect, the telephone set is off-hook, and the nuisance call countermeasure key provided on the operation / display section by the countermeasure selection detection section is operated. If this is detected, it is determined that the incoming call is a nuisance call.

  Therefore, when a user handles an incoming call by performing an off-hook operation, the line connection is continued until a predetermined time elapses from the on-hook operation even if the on-hook operation is performed by operating the anti-nuisance key when it is determined to be a nuisance call. Since the countermeasure sound is continuously output during that time, the countermeasure sound output is continued for a predetermined set time until the other party's telephone line is disconnected, so that the nuisance call suppression effect by the countermeasure sound output can be improved.

  Further, in the invention according to claim 5, in the telephone set according to claim 1 or claim 2, the telephone set includes means for storing at least a caller's telephone number and call arrival time as an incoming call history. When the number of consecutive incoming calls from the telephone number exceeds a predetermined number, the measure selection detecting unit determines that the incoming call is a nuisance call.

  Therefore, the telephone can be automatically identified as a nuisance call based on the caller telephone number and the number of consecutive incoming calls. In that case, the countermeasure sound output is continued until the other party's telephone disconnects the line, and the nuisance call suppression effect by the countermeasure sound output can be improved.

  Further, in the invention according to claim 6, in the telephone set according to any one of claims 1 to 5, the user can select whether or not the predetermined time is arbitrarily set and can start a call. It can be set later.

  Therefore, the user can select whether or not to set it arbitrarily, and can be set in the middle of communication. When a user wants to make a phone call, the user can set on-hook after performing a setting operation, and the effect of suppressing annoying calls can be further enhanced.

  Hereinafter, specific examples of the present invention will be described in detail with reference to examples and drawings. FIG. 1 is an external view showing a configuration of a telephone having an annoying telephone countermeasure sound output function according to an embodiment of the present invention. FIG. 2 is a block diagram showing a configuration of a telephone having an annoying telephone countermeasure sound output function according to an embodiment of the present invention. In this embodiment, the description will be made by taking a cordless telephone as an example. However, in addition to a cordless telephone, the present invention can be applied to a normal fixed telephone, a telephone having a facsimile function, a telephone to which a facsimile apparatus can be connected, a cordless telephone, and the like. .

  FIG. 1 is a diagram illustrating an appearance of a cordless telephone 10 according to a first embodiment of the present invention. In Example 1 below, when the cordless telephone 10 receives a nuisance call, the cordless telephone 10 is configured to output a countermeasure sound for suppression to the caller side, and the user then performs an off-hook operation for a telephone call. In this case, a configuration for re-acquiring the line after a predetermined time has elapsed will be described.

  The cordless telephone 10 has a configuration in which a parent device 20 and a child device 30 are connected wirelessly so that calls can be received and transmitted from the child device 30 via the parent device 20. As shown in the block diagram of FIG. 2, the base unit 20 includes a telephone line control unit 21, an audio signal processing unit 22, a radio unit 23, a control unit 24, a microphone / speaker unit 25, an operation / display unit 26, a memory 27, An antenna 28 is provided. The control unit 24 is a control circuit composed of a microprocessor and includes a ROM and a RAM (not shown). The ROM stores a program for controlling the operation of each unit, and a program for allowing the control unit 24 to measure a call time and to calculate a call charge is also written. Information necessary for the operation of the control unit 24 is stored in the RAM.

  The telephone line control unit 21 controls incoming calls from the public line N and outgoing calls to the public line N, and performs incoming call detection, dial tone detection, and the like. The voice signal processing unit 22 processes the received voice signal and outputs it through the microphone / speaker unit 25 or processes the transmission voice input through the microphone / speaker unit 25 and converts it into a voice signal. Send it out. The wireless unit 23 communicates a transmission signal, an incoming signal, a transmitted voice signal, and a received voice signal with the slave unit 30 via the antenna 28.

  The operation / display unit 26 includes a display, function keys, numeric keys, and the like. The numeric keys are used to input a telephone number when making a call, and the function keys are used to select and set various functions. It is done. That is, the function key is operated to display a desired function setting screen on the display to set various functions of the cordless telephone 10, and to set various service functions provided by the communication carrier on / off. be able to. For example, on / off settings such as a number display service, a call waiting display service, and a name display service can be set.

  Although not shown in the figure, the operation / display unit 26 is provided with a “measure selection key” for performing an operation for outputting a countermeasure sound such as a repelling sound when the user wants to judge the incoming call as a nuisance call. Yes. In addition, the control unit 24 is provided with a countermeasure selection detection unit 241 that detects when a countermeasure selection key is operated or when the base unit 20 determines that an incoming call is a nuisance call by determination described later. Further, the memory 27 is provided with a nuisance call countermeasure processing unit 271, a line connection continuation processing unit 272 for controlling connection continuation of the incoming line, a countermeasure sound (repelling sound) output control unit 273 for nuisance calls, and off-hook detection. A unit 274 and a line connection disconnection processing unit 275 are provided. These functions are substantially performed by the program control as in the operation procedure described later.

  As shown in the block diagram of FIG. 3, the slave unit 30 includes an audio signal processing unit 32, a radio unit 33, a control unit 34, a microphone / speaker unit 35, an operation / display unit 36, a memory 37, and an antenna 38. It is configured. The control unit 34 is a control circuit including a microprocessor, and includes a ROM and a RAM (not shown). The ROM stores a program for controlling the operation of each unit, and a program for the control unit 34 to communicate with the parent device 20 is also written therein. Information necessary for the operation of the control unit 34 is stored in the RAM.

  Whether or not the incoming call is a nuisance call can be determined by any of the following methods alone or in combination. The first is a case where the user determines that the incoming call is a nuisance call and operates the measure selection key. The second is a case where there is an incoming call that is repeated a predetermined number of times or more from the same source. In order to perform the second determination, the incoming call history shown in FIG.

  That is, as shown in FIG. 4, the incoming call history is configured to store the telephone number of the other party, the incoming time, the presence / absence of voice recording, and the number of incoming calls for each incoming call. The storage order advances the address of the storage unit in the order of arrival, and the order is from old arrival to new arrival. Therefore, if there is an incoming call from a telephone having the same telephone number at a continuous address, it can be determined that the incoming call is continuous by counting the number of incoming calls from that telephone number.

  According to another incoming call history storage method, it is configured to store the incoming time, voice recording presence / absence, and the number of incoming calls for each phone number of the incoming caller. For example, it is possible to count until the predetermined number of times is reached, and to clear the count value if the incoming time is not continuous. Accordingly, it is possible to determine that the incoming calls are continuous by referring to the number of incoming calls.

  In the first embodiment, when the countermeasure selection detection unit 241 automatically determines that it is a nuisance call, the line connection is established with the other party without going off-hook, and the countermeasure sound for the nuisance call is continuously output until the other party disconnects the line. . In addition, when the user determines that the call is a nuisance call and operates the countermeasure key after the line is connected off-hook and connected to the incoming telephone, the countermeasure sound output is continued for a predetermined time even if the user turns on the hook. These processes are performed under the control of the line connection continuation processing unit 272, the countermeasure sound output control unit 273, and the line connection disconnection processing unit 275. After that, when the user performs an off-hook operation for a telephone call, the off-hook detection unit 274 performs control so that the countermeasure sound output is stopped after a predetermined time has elapsed and the telephone call (calling) can be performed.

  The procedure of countermeasure sound output control for the above nuisance call in the base unit 20 will be described based on the flowcharts shown in FIGS. When there is an incoming call in the process of step S11, the telephone number on the calling side is acquired in the process of step S12. When the calling party telephone number is acquired, the countermeasure selection detection unit 241 determines whether it is the same as the calling party telephone number that has been previously received with reference to the incoming call history of FIG. 4 in the process of step S13.

  If they are the same, it is determined whether the number of incoming calls (continuous) exceeds a predetermined number (for example, 3 times) in the process of step S14. If the number of incoming calls (continuous) does not exceed the predetermined number of times, it is determined that the incoming call is a normal incoming call, the process proceeds to step S19, the timer A (first timer) is started, and a ringing tone is generated in step 20. When the predetermined number of times is exceeded, the measure selection detecting unit 241 determines that the call is a nuisance call, and enters the processing after step S15 to perform the measure sound output processing.

  That is, in the process of step S15, the line connection disconnection processing unit 274 connects the line, the countermeasure sound output control unit 273 outputs a countermeasure sound in the process of step S16, and records the call in the process of step S17 (recording function). If is not turned on, this process is skipped). In step S18, it is detected whether or not the other party has disconnected the line. If the line has not been disconnected, the process returns to step S16 to continue outputting the countermeasure sound. If a line disconnection is detected, the process returns to step S11 to return to an incoming call waiting state.

  On the other hand, after ringing the ring tone in the process of step S20, if the user goes off-hook in the process of step S21 for reception, the count of the timer A is cleared in the process of step S28, and step S29. In step S31, the ringing tone is stopped. In step S30, the line with the calling side is connected. In step S31, it is monitored whether the other side is disconnected. When it is detected that the other party has disconnected the line, the process returns to the process of step S11 to return to the incoming call waiting state.

  If the other party is not disconnected, the measure selection detection unit 241 performs an operation for outputting a countermeasure sound such as a repulse sound when the user wants to determine that the incoming call is a nuisance call in the process of step S32. It is detected whether or not a countermeasure selection has been performed by operating the “measure selection key” on the display unit 26. If the measure selection key has not been operated, the process returns to step S31 to continue monitoring the other party's line disconnection. During this time, it is needless to say that the parent device 20 performs a call operation with the other party.

  When the measure selection key is operated, the measure selection detection unit 241 determines that the call is a nuisance call, and enters the processing after step S33 and performs a measure sound output process. That is, the countermeasure sound output control unit 273 outputs a countermeasure sound in the process of step S33, and records, records, and counts the number of incoming calls in the process of step S34. In step S35, it is determined whether or not the handset is on-hook (call end). If it is not on-hook, it returns to the process of step S33 and the output of the countermeasure sound is continued.

  If an on-hook is detected in the determination process of step S35, the process proceeds to the process of step S40 in the flowchart of FIG. 6, and the process of the present invention is performed to continue outputting the countermeasure sound for a predetermined time. That is, even if the user puts the handset (on-hook) and terminates the call with the other party, the line is not disconnected and the output of the countermeasure sound is continued, thereby improving the effect of suppressing unwanted calls.

  Therefore, it is determined whether or not line disconnection is set in the process of step S40. If the time until line disconnection is not set, the process proceeds to step S44, and the line connection disconnection processing unit 274 immediately disconnects the line. If the time until line disconnection has been set, the line connection continuation processing unit 272 performs the process of continuing the line connection in the process of step S42, and the countermeasure sound output control unit 273 outputs the countermeasure sound in the process of step S42. Continue.

  In the process of step S43, for example, it is determined whether or not the line is disconnected due to the other party being on-hook. If it is determined that the line is disconnected, the line is disconnected in the process of step S44, and step S11 (see FIG. 5) is performed. Return to processing and return to waiting for incoming call. Otherwise, it is detected whether or not an off-hook operation has been performed in the process of step S45. If there is no off-hook operation, the process returns to step S43.

  If an off-hook is detected in the process of step S45, the line with the other party is disconnected in the process of step S46 (the countermeasure sound output is terminated), and timer B (second timer) starts counting in the process of step S47. . In step S48, it is determined whether the count value of timer B has elapsed for 2.2 seconds. If not, step S48 is repeated. If 2.2 seconds have elapsed, the line is determined in step S49. Connect.

  In the process of step S50, it is determined whether the call is a dial call. If the call is a dial call, the other party responds and then a call is started in the process of step S51, and the process proceeds to an on-hook detection process in step S52. If it is not dialing, it is detected whether or not it is on-hooked in the process of step S52. If on-hook is detected, the line is disconnected in the process of step S53, the call is terminated, and the process returns to step S11 to wait for an incoming call. Return. If no on-hook is detected in the process of step S52, the process returns to the process of step S50.

  On the other hand, in the flowchart of FIG. 5, after ringing a ring in the process of step S20, if the handset of the main unit 20 is not off-hooked in the process of step S21 and the timer A counts a predetermined time, the answering machine recording Enter the process. That is, in the process of step S22, the counting time of the timer A is determined. If the predetermined time has not been counted, the process returns to the process of step S20 and the ringing tone continues.

  When the count of the timer A elapses a predetermined time, the ringing tone is stopped in the process of step S23, the line with the other party is connected in the process of step S24, and recording is started. At the start of recording, an answering machine recording message is transmitted in the process of step S26. If the call (recording) is terminated in the process of step S27 and the other party disconnects the line, the process is terminated, and the process returns to the process of step S11 to return to the incoming call waiting state.

  As described above, when it is automatically determined that the call is a nuisance call, the line is connected to the other party without going off-hook, and the countermeasure sound for the nuisance call is continuously output until the other party disconnects the line (steps S13 to S18). ). In addition, when a user determines that it is a nuisance call and operates a countermeasure key after starting off-hook and connecting to the incoming telephone line, the countermeasure sound output is continued for a predetermined time even if the user is on-hooked ( Step S21 to Step S43). Thereafter, when the user performs an off-hook operation for a call, the off-hook detection unit 274 stops outputting the countermeasure sound after a predetermined time has elapsed, and enables a call (call) (steps S45 to S53).

  As a result, it is possible to continue the output of countermeasure sounds for unwanted calls even for on-hook operation, and for a certain period of time after an off-hook operation if you want to make a phone call to the police as soon as it is determined that it is an unwanted call. After that, you can automatically talk. Therefore, it is possible to further enhance the effect of suppressing unwanted calls.

  In the above-described embodiment, the configuration in which the presence / absence of the setting for continuing the countermeasure sound output until the predetermined period elapses in the process of step S40 after detecting the on-hook has been described, but this setting is arbitrarily set by the user. This setting may be made in advance before a call, or may be set from the operation / display unit 26 during the process from step S30 to step S35 (on-hook). It can also be configured to.

  In the first embodiment, as described in the procedure of steps S45 to S49 in FIG. 6, when an off-hook operation is performed while the countermeasure sound is being output for the nuisance call, the line is connected after 2.2 seconds have elapsed. As in Example 2 described below, if there is an off-hook operation while the countermeasure sound output for the nuisance call is continued, the countermeasure sound output is continued until a predetermined time elapses by the timer C (third timer). It is also possible to disconnect the line and connect (re-acquire) the line after 2.2 seconds and start the call.

  FIG. 7 is a flowchart illustrating an operation procedure of the cordless telephone according to the second embodiment, and illustrates processing corresponding to the flowchart of FIG. 6 in the first embodiment. In addition, the structure of the cordless telephone in Example 2 is the same structure as the structure shown in FIGS.

  The processes in steps S50 to S55 and steps S60 to S67 in FIG. 7 are the same processes as the processes in steps S40 to S45 and steps S47 to S53 in FIG. 6, respectively. The procedure different from the process of FIG. 6 is the process of steps S56 to S60.

  That is, if off-hook detection is detected in the process of step S55, the line connection with the other party is maintained in the process of step S56, and the countermeasure sound output is continued in the process of step S57. Then, counting by the timer C (third timer) is started in the process of step S58, and it is determined by the process of step S59 whether a certain time, for example, “1 minute” in this embodiment has elapsed. When one minute has elapsed, the line with the other party is disconnected in the process of step S60. If one minute has not elapsed, the elapsed time monitoring in the process of step S59 is continued.

  With this configuration, if there is an off-hook operation while the countermeasure sound output for the nuisance call is continued, the countermeasure sound output is continued until a predetermined time elapses by the timer C (third timer), and then the line is disconnected. After 2.2 seconds, the line connection (recapture) can be started and the call can be started.

  Further, in the first and second embodiments, when a predetermined number of consecutive calls are received from the same telephone number, it is automatically determined as a nuisance call, and when a user during a call operates a “measure selection key” for nuisance call countermeasures. Although an example of performing countermeasure sound output has been described, it is also possible to automatically activate the countermeasure selection key when a predetermined period of time elapses when the user goes off-hook and is silent after connecting the line.

  FIG. 8 is a flowchart illustrating an operation procedure of the cordless telephone according to the second embodiment, and illustrates processing corresponding to the flowchart of FIG. 5 according to the first embodiment. In addition, the structure of the cordless telephone in Example 3 is the same structure as the structure shown in FIGS.

  In the flowchart shown in FIG. 8, a procedure different from the flowchart of FIG. 5 is that a processing procedure of steps S91 to S95 is added. Other procedures are the same as the processing procedure of FIG.

  That is, when a line connection is made in the process of step S90, the measurement of the silent period is started in the process of step S91. In the process of step S92, it is determined whether the silent period has elapsed 10 seconds. If 10 seconds have not elapsed, the call state is continued in the process of step S93, and it is determined whether the line is disconnected in the process of step S94. If the line is not disconnected, the process returns to step S92 and the silent period is continuously monitored. When the line is disconnected, the process returns to step S57 to return to the incoming call waiting state.

  Note that the silent period detection in step S91 is a silent period for only the other party that has made a call for the purpose of mischief.

  If it is detected in the process of step S92 that the silent period has elapsed for 10 seconds, the countermeasure selection detection unit in a process of step S95 enables the countermeasure sound to be output when the countermeasure selection key is operated. In other words, the output of the countermeasure sound is prohibited until step S91. Further, in the process of step S97, it is determined whether or not the “measure selection key” has been operated. When the “measure selection key” is operated, the procedure proceeds to the procedure for outputting the countermeasure sound as in the first embodiment.

  With this configuration, the countermeasure sound can be automatically output when a predetermined period of time elapses when the user goes off-hook and is silent after the line is connected.

  As described above in detail, according to the present invention, when a side receiving a nuisance call or a mischievous phone outputs a repulse sound, a countermeasure sound (repulse sound) is continuously output for a certain time after on-hook, When a user goes off-hook for a call, the line can be automatically re-acquired after a predetermined period of time, and the effect of suppressing nuisance calls can be enhanced by outputting countermeasure sounds. Then, if you want to make a phone call to the police immediately, you can automatically re-acquire the line if you go off-hook.
