SIP Trunking

It’s clear, enterprises want to move to SIP Trunks to reduce costs and enable the use of IP communication and collaboration across organizational boundaries. But there are some significant obstacles in their path, including their existing PBXs.

Large enterprises have hundreds, in some cases thousands of PBXs from multiple vendors and although most vendors support SIP, the degree and nature of that support varies across vendors. As a result getting the existing versions of PBXs integrated into the SIP Trunk and interoperable across PBX boundaries is a difficult, resource intensive and expensive task.

Until now. Covergence, the leader in the enterprise Session Border Controller (SBC) solutions, transforms vendor-specific SIP dialects into a signaling stream that is compatible with both the SIP Trunking service provider and the target PBXs. With Covergence you can quickly and easily integrate Avaya, Cisco, Nortel, Siemens, and other PBXs as well as various Unified Communications solution into your SIP Trunking service.

And there's much more. With Covergence the security, business and operations teams get the policy-based security, control, and monitoring they need to deploy SIP Trunks, connect remote teleworkers and replace PBX tie-lines between sites.
