VoIP Termination

VoIP international trunking is an important business that generates important revenues. The idea behind this is to offer low-cost long-distance calls. An operator transports the calls using the Internet Protocol, being able this way to offer very cheap call rates to its customer.

The calls are ended on classical fixed or mobile telephone networks. For this reason the operator needs signaling and media gateways on the interconnection side. For call-control, call-routing, media-gateways control there is also need for a softswitch element in the network. Topex multiswitch and Topex Media Gateways can be a complete solution for VoIP termination.

Topex solutions can act also as a SIP H323 gateway. This way, the SIP H.323 signaling translation is realized into a proprietary box which completes the overall solution without the need to face multi vendors' equipment interconnections.

Once you have to deal with multiple providers, using different types of signalizations, you need to convert protocols. Topex media gateways can provide this function for multiple types of protocols including SIP and H323.

The traffic comes in the central softswitch situated in the NOC and it is then routed to proper gateway. You can beneficiate of the very powerful routing features of Topex multiSwitch. Routing of voice packets can take into consideration the following aspects:

          Gateway availability - as Topex multiSwitch knows the state of each gateway it controls;

          ASR of gateways - Answer Seizure Rate is an important factor when wholesaling VoIP services. Wholesalers want to avoid terminating traffic on gateways with small ASR.

          ACD of calls - Average Call Duration can tell the media of the call duration.

          Gateway priority - the gateways can have diverse priorities.

          On the interconnection side Topex multiAccess for VoIP-GSM calls and Topex miniGateway, Topex Qutex or Topex Eones for VoIP-PSTN calls can be used. The advantages with these gateways are modularity, scalability and the wide-range of signaling protocols they support.
