AT&T will roll out a network-based VoIP service to a limited number of business customers

Called AT&T Voice Dynamic Network Applications (DNA), the service is part of a portfolio of IP services that AT&T is planning to introduce.

The new portfolio will support business communications with voice, conferencing, and messaging features. The services will adhere to standards and be capable of operating with third-party providers, AT&T said.

AT&T Voice DNA will be introduced soon and will continue to be rolled out through the remainder of the current year, the company said.

"AT&T Voice DNA is a VoIP solution for enterprise branch offices and remote locations, as well as for smaller businesses," AT&T said in an announcement. "This service offers enhanced telephony features and 'any distance' calling plans, and provides a full suite of management capabilities and end-user tools."

AT&T said its offering will support some IP phones from Cisco and Polycom as well as selected IP PBXs from Cisco and Avaya.
