AT&T Adds VoIP Service to Enterprise VPN Service

AT&T began offering a VoIP service to its virtual private network (VPN) customers. The converged solution will enable customers to consolidate their separate voice and data networks, reduce equipment and maintenance costs, and simplify migrating these complimentary capabilities to a common, secure infrastructure.


The AT&T VoIP portfolio is also certified for interoperability with leading industry providers of IP-PBX systems, such as SIP Trunking services qualified for Microsoft Office Communications Server 2007 R2, providing support for businesses planning to incorporate a comprehensive unified communications solution in the future.
