VoIP (Voice Over Internet Protocol, ip voice) technology is carried out the 1:1 transformation to traditional telephone network, the subscribers feeder that stored-program control exchange is connected analog telephone, be connected to the trunk interface of voip gateway, FXO (Foreign Exchange Office for example, FXO) interface, this FXO interface and the binding of IP phone.Following trunk interface is that example describes with the FXO interface, and except that specified otherwise, the trunk interface in the present specification is corresponding one by one with the binding relationship of IP phone.
After using voip technology to the PBX network rebuilding, the PBX network as shown in Figure 2, the FXO interface of binding with the IP phone is all passed through in the calling between PSTN and the IP phone.
After using voip technology to the PBX network rebuilding, the user can use the IP phone to communicate by letter with analog station, can effectively reduce the calling cost.But in the improved PBX network, the Call Forwarding services of IP phone will produce relay resource and take chaotic problem.The production process of this problem is as follows:
As shown in Figure 3, the operation flow of Call Forwarding comprises in the PBX network before the transformation:
In the 1st step, phone B off-hook is also imported * 57*C telephone number # (PSTN Call Forwarding characteristic codes), registers the unconditioned call connection business to stored-program control exchange.
In the 2nd step, phone A dials B, stored-program control exchange directly with Call Forwarding to phone C, PBX connects A and converses with C.
As shown in Figure 4, use voip technology to the PBX network rebuilding after, the flow process of the Call Forwarding services of IP phone comprises:
In the 1st step, IP phone B registers the Call Forwarding Unconditional business by phone menu or direct incoming traffic characteristic codes to VoIP Server.
