This converged solution is said to 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.
By migrating to a common infrastructure, customers are able to take advantage of additional applications as AT&T makes them available, such as unified communications capabilities.
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, optimizing their equipment investment."
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.
AT&T customers can access their VPN using virtually any access technology, such as mobile, Wi-Fi, DSL, dial-up and Ethernet.
“Voice service is as mission-critical for businesses today as it’s ever been, and customers expect their VoIP service to perform as well as their traditional telephone service,” said Shawn Conroy, vice president, AT&T Business Solutions.
"Adding voice to the network cloud gives customers the ability to determine their optimal level of security, architecture, cost and performance objectives — key differentiators for AT&T,” he said.
According to AT&t, Today, the company offers Multi-protocol Label Switching (MPLS)-based services to 163 countries over 3,800 service nodes, and operates 38 Internet data centers around the world. These assets enable AT&T to provide customers with globally-consistent access to capacity and features – when and where they need it most.
