BT Launches SIP Trunking Option

The BT Onevoice converged communications platform has been enhanced with SIP trunking in a number of countries, providing full connectivity between domestic country voice services and BT's Onevoice global VPN.


The service offers local numbering for both outgoing and incoming call traffic that can be delivered anywhere on a user's network. Already available in the UK, the services will be rolled out to the Netherlands, Belgium, Germany, France and the US in the coming months, with further regions, including Spain, to follow. In addition, by utilizing SIP trunking, customers can reduce rental for access lines, reduce call costs, and improve collaboration for users, whether they be office based, on the move or based remotely.


In addition, BT OneVoice has gained global qualification for connecting directly to Office Communications Server 2007 R2. Office Communications Server 2007 R2 users can now streamline communications by combining presence and instant messaging interoperability with BT Onevoice conferencing, and software-powered voice over IP in a single, unified platform globally.


"SIP trunking gives customers the capability to introduce collaboration applications which increase productivity and save cost. The Microsoft qualification will open the door to further developments within the combined BT and Microsoft portfolio, creating a platform for innovation inside BT Onevoice all in a security-enhanced global environment," says Neil Sutton, Vice President, Global Portfolio, BT Global Services.
