AT&T has announced that new and existing virtual private network (VPN) customers may add VoIP service to the network solution delivered over AT&T’s global network cloud. This converged solution will enable customers to consolidate their separate voice and data networks.
The AT&T VoIP portfolio is 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.
The company’s portfolio of VoIP services includes AT&T IP Flexible Reach, a SIP trunking service, which allows businesses to continue to use the capabilities of their existing IP-PBXs. AT&T Voice DNA, another product in the VoIP portfolio, is a fully hosted network-based service with advanced features, applications and management tools for customers.
With AT&T’s VPN portfolio, businesses can use a single infrastructure (their VPN network) to connect branch offices, headquarters, remote users, and third parties such as suppliers and customers. AT&T customers can access their VPN using virtually any access technology, such as mobile, Wi-Fi, DSL, dial-up and Ethernet.
