AT&T Dual-Mode Mobile Voice

Mobilize Enterprise Voice across Cellular and Campus Wi-Fi

Mobilize your enterprise communications across cellular and campus Wi-Fi networks

As an AT&T business customer, you can mobilize your enterprise voice using cellular and campus Wi-Fi networks with AT&T Dual-Mode Mobile Voice (DMMV). The DMMV solution provides you with enhanced user productivity, extended reachability, and improved office/campus coverage, while helping control your business costs by converging mobile and wireline calling capabilities through your designated PBX.

A converged fixed-mobile solution

DMMV allows you to treat an enabled dual-mode mobile device (Wi-Fi+Cellular) as a station on its PBX. Calls originating on the enabled mobile device (through a cellular network or enterprise campus Wi-Fi network) can be routed for completion, or terminated on the enabled device, through your designated PBX over an eligible AT&T wireline transport service. The call routing for both originating and terminating calls is based solely on the pre-established routing parameters of your PBX. Qualified users can make and receive calls from their smartphones using a number assigned in the enterprise PBX to the mobile device.*

When a cellular network and a campus Wi-Fi network are both available, DMMV selects a network for the call based on signal strength, battery life, and network preference. As these factors change, the call is transitioned between the cellular and campus Wi-Fi networks.

Potential benefits

• Ability to use on-campus Wi-Fi helps ensure robust coverage.
• Extension of select PBX features to qualified mobile devices can enhance usability.
• Utilization of campus Wi-Fi for call transport can reduce cellular usage charges.
