AT&T IP Flexible Reach

What AT&T IP Flexible Reach is

AT&T IP Flexible Reach is a SIP trunking service for businesses with premises-based telephony equipment. It provides inbound, outbound, local, and long-distance calling, while letting businesses add SIP trunking to an existing PBX and keep their current voice equipment. Voice and data share an integrated access circuit. Customers can scale concurrent call channels to the number of lines they need, and branch extensions can share trunks across locations. The service also connects premises-based or cloud-based Microsoft Teams PBX to the public switched telephone network. Teams integration can use a customer-provided Microsoft Teams-certified Session Border Controller or one hosted and managed by AT&T. AT&T says calls travel over its MPLS network rather than the public internet; on-net VoIP-to-VoIP calls within its network do not incur additional charges. A web portal offers performance and call-detail reporting plus e-ordering. Network access requires AT&T Dedicated Internet Service or AT&T Virtual Private Network for high-speed dedicated access. Pricing is on request.
