Description

The present invention provides a telephone device that accommodates a plurality of extension terminals.
The present invention relates to a ringing tone of an extension terminal incoming call display pattern as a transfer destination at the time of incoming call transfer (non-response transfer) or call transfer (intermediate transfer).

When a conventional call control device is used, when a communication terminal receives an incoming call and a ringing sound is generated, whether the incoming call is originally intended for the communication terminal or another communication terminal is forwarded. However, there is a problem that an inappropriate response occurs in some cases and an unnecessary burden is imposed on the telephone agent. On the other hand, Patent Document 1 adds to the communication terminal information that distinguishes between a normal incoming call that directly calls the communication terminal and an incoming call based on incoming call transfer, thereby receiving an incoming call. A technique for notifying an incoming call and an incoming call at the time of incoming call transfer using different incoming call display patterns (ringtones) is disclosed (Patent Document 1).
JP 2008-236214 A

  However, in the technique disclosed in Patent Document 1, it is possible to discriminate between two types of incoming calls, that is, a case where the communication terminal is directly called and a case where the communication terminal is called by transfer. Since it is impossible to identify who the call is for by the ring tone, there are still problems such as an inappropriate response and an unnecessary burden on the telephone agent.

The present invention has been made in view of the problem, and in a call control apparatus that accommodates a plurality of external lines or extensions and has a call transfer function for transferring a call that has arrived at a predetermined extension to another extension, An incoming line user corresponding incoming call display pattern registering means for registering a display pattern in association with each extension user, and a specific incoming call display pattern registered in the said incoming line user corresponding incoming call display pattern registering means or the specific incoming call display pattern is designated An incoming call display pattern sending means for sending a code to be sent to a predetermined extension,

  When there is an incoming call to an extension user for which incoming call forwarding is set, the incoming call display pattern sending means refers to the incoming call display pattern registration means for the extension user, and a specific incoming call corresponding to the extension user who has received the incoming call There is provided a call control device having a specific incoming call display pattern sending function, wherein a display pattern or a code designating the specific incoming call display pattern is sent to an extension of a transfer destination to be called.

According to the present invention, it is possible to make a call with a ring tone corresponding to the user who wants to call without depending on the extension terminal of the called party, and that the other party (individual) to be called also at the forwarding destination has received an incoming call for himself / herself. It becomes easy to recognize, and the other party at the transfer destination does not respond, so that the other party who wants to call can answer directly, and a smooth telephone response is possible.

FIG. 2 is a diagram showing an example of the contents of an extension user corresponding incoming call display pattern registration unit of the call control device according to the present invention; FIG. 3 is a diagram showing an operation flow of a call control unit during call transfer, FIG. 4 is a diagram showing an operation flow of a call control unit at the time of call transfer in which a call destination user is designated.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a block diagram of a call control device according to the present invention. A call control device 2 that accommodates an external telephone network 1, an extension terminal A3, and an extension terminal B4 includes An extension circuit A211 connected to the extension terminal A3, an extension circuit B212 connected to the extension terminal B4, a transmission line switch 215 for delivering voice signals and control signals, a call control unit 220 for controlling outgoing / incoming calls and transfers, Corresponding to an incoming line display pattern registration unit 221 for storing an incoming line display pattern different for each user and an incoming line display pattern instructed from the call control unit 220. A ring tone is read from the ring tone data storage unit 233 and sent to the extension terminal A3. The incoming call display pattern sending circuit A231 and the incoming call display sent to the extension terminal B4. And a turn delivery circuit B232.

  Also, the user A (5a) and the user C (5c) are usually present at the place where the extension terminal A3 is installed, and the user B (5b) is usually present at the place where the extension terminal B4 is installed. Although being present, FIG. 1 shows a state in which the user A is currently moving to a place where the extension terminal B4 is installed, and an incoming call from the external telephone network 1 once arrives at the extension terminal A3. However, since the user A is absent, it is assumed that the user A is transferred to the extension terminal B4.

  In this call control device 2, when the incoming call from the external telephone network 1 is detected by the external line circuit 201, the call control unit 220 first receives the incoming call to the extension terminal A 3, and transmits the incoming call display pattern transmission circuit A 231 to the transmission line. A ring tone is sent to the extension terminal A3 via the switch 215.

  Then, when the extension terminal A3 is in use or does not respond for a predetermined time, the call control unit 220 transfers the incoming call to a transfer destination designated in advance (here, the extension terminal B4), or from the extension terminal A3. When a call transfer request is received, the incoming call is transferred to a designated transfer destination (also referred to as extension terminal B4 here).

  In the present invention, when calling the extension terminal B4 as a transfer destination, the call control unit 220 selects a ring tone corresponding to the designated user (here, user A) and transmits it from the incoming call display pattern sending circuit B232. A ring tone is sent to the extension terminal B4 via the route switch 215. Before explaining the operation contents, FIG. 2 will be explained.

FIG. 2 is a diagram showing an example of the contents of the extension user corresponding incoming call display pattern registration unit 221 of the call control device 2 according to the present invention.
A user name (V2211), a telephone number (V2212) for receiving an outside line for specifying a call destination when an incoming call is received, a corresponding call extension number (V2213), and a user identification number (V2214) for specifying a call destination user, respectively And a ring tone display pattern (V2215) associated with each user.

When an external line is received, the external line incoming call display pattern registration unit 221 is searched using the external line incoming telephone number (V2212) sent from the external telephone network 1 as a key, and the corresponding call destination extension number (V2213) is associated. Incoming call display pattern (V2215) information is acquired.
In addition, when a call is transferred, the extension user-corresponding incoming call display pattern registration unit 221 is searched using the user identification number (V2214) sent by dial from the person instructing the transfer as a key, and the corresponding incoming call display pattern (V2215) information To get.

  In addition, if the information corresponding to the incoming line incoming telephone number sent from the external telephone network 1 is not registered in the internal user incoming call display pattern registration unit 221 or sent from the person who instructs the transfer at the time of call transfer. If the information corresponding to the received user identification number is not registered, a normal incoming call display pattern (here, Default.wav) that does not specify the user is selected (V2216).

  In this way, when the call control unit 220 acquires the incoming call display pattern information corresponding to the incoming user (here, user A) from the extension user corresponding incoming call display pattern registration unit 221, the call control unit 220 selects the incoming call display pattern sending circuit A231, Notice. The incoming call display pattern sending circuit A231 reads the incoming melody corresponding to the incoming call display pattern notified from the ringtone data storage unit 233, and sends it to the called extension terminal A3 via the transmission path switch 215.

  When an incoming call or call transfer is made to the extension terminal B4, the call control unit 220 selects the incoming call display pattern sending circuit B232 and similarly displays the incoming call corresponding to the incoming user (here, user A). Notify the pattern transmission request. The incoming call display pattern sending circuit B232 reads out the incoming melody corresponding to the incoming call display pattern notified from the ringtone data storage unit 233, and sends it to the transfer destination extension terminal B4 via the transmission path switch 215.

  The incoming call display pattern (V2215) information according to the present embodiment uses the file name of the sound source data file of the incoming melody stored in the incoming call tone data storage unit 233, but the incoming call display pattern is limited to the incoming melody. Various ringing sounds may be used.

  FIG. 3 shows an operation flow of the call control unit 220 when there is an incoming call from the external telephone network 1 and once arrives at the extension terminal A3 and then calls the extension terminal B4 by call transfer.

  In FIG. 3, when the incoming call from the external telephone network 1 is detected by the external line circuit 201 in the standby state (S2000) (S2001, Y), the call control unit 220 receives the incoming call from the external telephone network 1 The extension user-corresponding incoming call display pattern registration unit 221 is searched using the telephone number as a key, and the user name (V2211), the called telephone number (V2213), and the incoming call display pattern (V2215) information corresponding to the user are acquired ( S2002).

  Next, the call control unit 220 sets the extension terminal to the incoming call display pattern sending circuit A according to the acquired incoming call information (here, the user A, the called extension number 211, ie, the extension terminal A3, and the incoming call display pattern Melodytype1.wav). A3 is instructed to send the ringtone data of Melodytype1, and the incoming call display pattern sending circuit A231 receiving the instruction reads the corresponding sound source data from the ringtone data storage unit 233, and the extension terminal A3 via the transmission path switch 215 Melodytype 1 is transmitted as a ringtone (S2003).

  Next, when the call transfer function is set (S2004, Y), the call control unit 220 activates a response monitoring timer (S2005), and monitors the response of the extension terminal A3 (S2010).

  When the extension terminal A3 responds (S2010, Y), the ringing tone transmission from the incoming call display pattern transmission circuit A231 is stopped (S2011), and the communication path between the extension terminal A3 and the external telephone network 1 is set by the transmission path switch 215. Connect (S2012), and transition to a call state.

  In the call state, when the destination extension terminal A3 or the other party of the external telephone network 1 ends (disconnects) the call (S2071, Y), the call path connected in step 2012 is released (S2072), and the standby state (S2000). Return to).

  On the other hand, if the incoming call from the external telephone network 1 is canceled before the extension terminal A3 responds (S2020, Y), the ringing tone transmission from the incoming call display pattern transmission circuit A231 is stopped (S2021), and the standby state is established. Return to (S2000).

  In step 2020, when the extension terminal A3 does not respond to the incoming call (S2020, N), and when the expiration of the response monitoring timer is detected (S2030, Y), the call control unit 220 receives the incoming call display pattern transmission circuit A231. After stopping the ringing tone transmission (S2031), the incoming call is transferred to the extension terminal B4 which is a preset incoming call transfer destination. At that time, the call control unit 220 receives the incoming call display pattern Melodytype1. The incoming call display pattern sending circuit B232 is instructed to send wav to the extension terminal B4. Upon receipt of the instruction, the incoming call display pattern sending circuit B232 reads the ringtone Melodytype1 corresponding to the user A from the ringtone data storage unit 233, and sends Melodytype1 as the ringtone to the extension terminal B4 via the transmission path switch 215 ( S2040).

  Next, when the incoming call is canceled before the extension terminal B4 that received the transfer responds (S2050, Y), the ringing tone transmission from the incoming call display pattern transmission circuit B232 is stopped (S2051), and the standby state Return to (S2000).

  When the extension terminal B4 responds (S2060, Y), the ringing tone transmission from the incoming call display pattern transmission circuit B232 is stopped (S2061), and the transmission path switch 215 establishes a communication path between the extension terminal B4 and the external telephone network 1. Connect (S2062) and form a call state.

  In the call state, when the call destination of the transfer destination extension terminal B4 or the external telephone network 1 ends (disconnects) the call (S2071, Y), the call path connected in step 2062 is released (S2072), and the standby state (S2000). Return to).

  In the present embodiment, the incoming call display pattern sending circuits 231 and 232 are described as playing the ringtone acquired from the ringtone data storage unit 233 as voice data. However, the ringtone sound source is provided on the extension terminal side. The extension terminal may determine the ring tone to be played back by the ring tone sound source based on the ring tone designation code signal received from the incoming call display pattern sending circuit (separately set code signal corresponding to the incoming call display pattern). .

  Also, in this embodiment, the incoming call display pattern that is different for each user is described as a difference in the ringtone (acoustic signal such as a melody), but the visual timing such as the blinking timing and lighting color of the incoming call display lamp on the extension terminal side is explained. Different display differences may be used for display.

  FIG. 4 shows an operation flow of the call control unit 220 when calling the extension terminal B4 by call transfer.

  In FIG. 4, when the incoming call from the external telephone network 1 is detected by the external line circuit 201 in the standby state (S2000) (S2101, Y), the call controller 220 receives the external line incoming telephone number received from the external telephone network 1 Using the as a key, the extension user corresponding incoming call display pattern registration unit 221 is searched, and the corresponding user name (V2211), called telephone number (V2213), and incoming call display pattern (V2215) information are acquired (S2102).

  Next, based on the acquired incoming information (in this case, the user C, the called extension telephone 211, ie, the extension telephone A3, Melodytype3.wav), the incoming display pattern sending circuit A receives the Melodytype3 incoming call to the extension terminal A3. The incoming call display pattern sending circuit A231 that gives an instruction to send the display data reads out the corresponding sound source data from the ringtone data storage unit 233 and receives the melodytype3 as a ringtone to the extension terminal A3 via the transmission path switch 215. Is sent out (S2103).

  Next, when the user C (5c) closest to the extension terminal A3 responds to the incoming call (S2110, Y), the call control unit 220 stops sending the ringtone from the incoming call display pattern sending circuit A231 (S2111), The communication path between the extension terminal A3 and the external telephone network 1 is connected by the transmission path switch 215 (S2112), and the communication state is set.

  Next, when the other party of the extension terminal A3 or the outside telephone network 1 ends (disconnects) the call (S2310, Y), it is determined that the outside line call is finished, and the transmission line switch 215 is controlled to control the extension terminal A3 and the outside telephone network. 1 is released (S2311), and the process returns to the standby state (S2000).

  Also, when the user C (5c) of the extension terminal A3 continues the call with the outside line, the call transfer is activated during that time, and the transfer is instructed to the extension terminal B4 which is the destination of the user A (5a) (S2320, Y), it is determined whether or not an extension user designation command (V2214) for designating the call destination user has been sent following the dial operation for designating the extension terminal B4 as the transfer destination (S2321). Specifically, an extension user designation command receiving unit (not shown) determines whether or not the user identification number (V2214, here 8611) sent by dialing operation is received following the dial reception of the extension terminal B4. To do.

  When the user designation (here, user A is designated) is performed (S2321, Y), the call control unit 220 receives the extension user corresponding incoming call display pattern registration unit 221 and receives the user identification number for user designation ( Here, the search is performed using 8611) as a key, and the incoming call display pattern Melodytype 1. Wav is acquired, and the incoming call display pattern sending circuit B232 is instructed to send the incoming call display pattern Melodytype 1 corresponding to the user A to the extension terminal B4 (S2342).

  Upon receipt of the instruction, the incoming call display pattern sending circuit B232 obtains the incoming call display pattern Melodytype1 sound source information corresponding to the user A (5a) from the ringtone data storage unit 233, and then receives the incoming call to the extension terminal B4 via the transmission path switch 215. Melodytype 1 is transmitted as a sound (S2043).

  If the user name of the call destination is not specified in step 2321 (S2321, N), the call control unit 220 sends an incoming call display pattern sending circuit B232 of a normal ringtone (here, Default.wav) that does not specify the user. Sending is instructed (S2341).

  Next, when the other party on the outside telephone network 1 ends (disconnects) the call (S2350, Y), the ringing tone transmission from the incoming call display pattern transmission circuit B232 is stopped (S2351), and the process returns to the standby state (S2000).

Next, when the extension terminal B4 responds to the incoming call display of the transfer (S2360, Y), the transmission of the ringing tone from the incoming call display pattern sending circuit B232 is stopped (S2361), and the extension terminal B4 and the external telephone are transmitted by the transmission line switch 215. A call path with the network 1 is connected (S2362), and a call state is formed.

  In the call state, when the call destination of the transfer destination extension terminal B4 or the external telephone network 1 ends (disconnects) the call (S2371, Y), the call path connected in step 2362 is released (S2372), and the standby state (S2000). Return to).

  In this embodiment, a dial operation for designating a call destination user is accepted together with a dial operation for designating a transfer destination extension terminal at the time of call transfer. The designated dial operation may be accepted and reflected in the incoming call display pattern.
