Summary of the invention

The object of the present invention is to provide a kind of implementation method based on the call pick-up business of internet voice gateway that can realize call pick-up.

For achieving the above object, the implementation method of the call pick-up business based on the internet voice gateway provided by the invention comprises:

Step 1: subscriber equipment sends call request to connected voice gateways;

Step 2: voice gateways judge according to the call request that receives, if this asks to answer for request call generation, then voice gateways judge whether answered equipment by generation is had to call out and arrive, if do not have, and end operation, otherwise finish the calling switching of the equipment of being answered by generation.

When voice gateways learn that through judgement the call request that receives is other operations, then finishes corresponding operating according to request in step 2.

Because the present invention can guarantee on the voice gateways basic call connection basis, utilize the characteristic of hardware of voice gateways own and operating system to realize the call pick-up business, both can finish the basic communication function of voice gateways, the calling that may fail can be continued by the another one communication equipment again, thereby reduced the possibility of communication failure, expanded the range of application of voice gateways.

Description of drawings

Fig. 1 is the embodiment flow chart of the method for the invention;

Fig. 2 is a principle schematic of the present invention.

Embodiment

The present invention is described in further detail below in conjunction with accompanying drawing.

Still in time do not answer the communication failure problem that unattended communication equipment causes for solving, can solve the communication failure problem that the communication equipment unattended operation causes by the mode of existing call pick-up when near the communication equipment Attended mode of called communication device unattended operation.With Fig. 2 is example, as calling to called communication device B, if this moment called communication device B ring unanswered, then can use communication equipment C promptly to can be communication equipment B and carry out call pick-up, prevent this communication failure, so just solved the problem that called equipment unattended operation causes communication failure.Shown in Figure 2, when communication equipment A when the communication equipment B that is connected with network makes a call, at first connect voice gateways 2 by voice gateways 1, connect communication equipment B by voice gateways 2 again, if communication equipment B is the ring unanswered, then communication equipment C answers the call of communication equipment B by the call pick-up service.

Fig. 1 is the embodiment flow chart of the method for the invention.According to Fig. 1, the present invention mainly comprises the call pick-up processing of request.Be not limited only to voice gateways in the described voice gateways reality embodiment illustrated in fig. 1, it can also be any all devices that voice-over-net (VOIP/VOFR) business is provided, the equipment that for example comprises the Internet telephone calls control function module, this equipment can provide the ability that detects the Dual Tone Multifrequency number, like this, behind the DTMF number of communication equipment output that makes a call, hand over voice gateways to handle the DTMF number that identifies, the Internet telephone calls control function module of voice gateways is according to the DTMF number that receives, just can finish request call generation and answer, thereby finish the operation of user's appointment.

As the user in step 1 by caller equipment to the voice gateways that the are attached thereto request of making a call, the voice gateways that receive request are judged the character of this request according to the call request of user's input, if this asks then to finish corresponding operation in step 3 into other operation beyond the call pick-up; If this asks to be the call pick-up request, then judge in step 4 this generation answers whether the number corresponding equipment exists and whether exist call request to arrive, if arbitrary situation does not just exist in step 5 to the prompting that makes a call for the user response operating mistake of answering; Exist call request to arrive simultaneously if the equipment of being answered by generation of this number correspondence exists, then transfer the call to for answering equipment in the request of step 6 according to the user.In above-mentioned steps 6, also comprise the state of judging the equipment of being answered by generation, if this equipment is in free time or talking state, just to the prompting that makes a call for the user response operating mistake of answering, only when being answered equipment and be in the ring indicating status by generation, could transfer on the generation equipment of answering that makes a call the calling of being answered equipment by generation, realize the call pick-up service.

If an equipment that is connected on the voice gateways (is assumed to be phone B, number is ABCD), when receiving from the IP phone of network side, an equipment that is connected on these voice gateways calls out (being assumed to be phone A), the ring of phone B receipt of call, and prompting has the arrival of calling.At this moment, if the operator of phone C wants the A that receives calls, can be by input " * 51*ABCD# ", the ABCD representative is as the phone B that is answered by generation, and # represents the end of input sign.Voice gateway equipment detects " * 51*ABCD# " number sequence of user's input, navigates to phone B according to number ABCD, will transfer to phone C place to the calling of phone B, simultaneously phone B is returned to initial condition.
