The new Unified Communications Proxy (UCP) enables the Tenor to provide ‘Any to Any’ connectivity between the unified communications cloud, the Public Switched Telephone Network (PSTN), TDM equipment and SIP VoIP equipment. This means Tenor can switch SIP to SIP calls, TDM to TDM calls and SIP to TDM calls, assuring easy integration into any existing voice network. This flexibility allows service providers to deploy VoIP to customer premises, regardless of whether the existing network supports SIP, TDM switching, or both.

Another key feature the UCP brings to Microsoft Office Communications Server 2007 is that it can support multiple gateways off of one Microsoft mediation server. This allows enterprises to support branch offices with legacy PBXs, IP-PBXs, analog and modem-based endpoints, as well as UC clients, without needing to deploy a Mediation Server at every branch location. This constitutes a tremendous savings for enterprises.

The UCP also provides the ability to support fax capabilities in a Microsoft OCS environment. The Unified Communications Proxy provides offers a ‘fax around’ for Microsoft Office Communications Manager 2007 by interpreting and routing calls directed between the fax machines and the PSTN.
