A converged network solution

Build a new outlook on how your voice service benefits your bottom line and overall productivity. AT&T IP Flexible Reach is a SIP trunking service that delivers integrated access for IP PBX, TDM PBX or Key System environments, providing potential total cost benefits through the consolidation of voice and data – one provider, single transport, and management options.

Voice and data traffic riding over the same transport drives greater bandwidth utilization and potential access to cost savings.

Centralized call delivery and branch office IP PBX extensions

Centralized call delivery allows routing of calls originating from various locations across the country and answering them at your preferred central location.

The branch office IP PBX extensions capability delivers telephone numbers for all your branch office sites and is supported by a single centralized IP PBX located at your IP Flexible Reach site. You can use your existing IP data network to distribute the calls to your branch office sites, which allows you to utilize your IP PBX to support IP phones without additional hardware.

*Limitations do apply to Virtual Telephone Numbers. Please see the BVoIP Service Guide for details on limitations and conditions of use.
