AT&T and Verizon Work toward VoLTE Interoperability

Verizon and AT&T are working to establish VoLTE interoperability between their networks.

The companies are working through a full set of requirements, beginning with extensive testing in lab environments and then moving to field trials.  This approach ensures customers will have a seamless experience making VoLTE HD Voice calls between networks and lays the foundation for interoperability of other Rich Communications Services (RCS) such as video calls, rich messaging, and more in the future.


VoLTE interoperability between Verizon and AT&T customers is expected in 2015.  

"Interoperability among all VoLTE providers takes connectivity to the next level with HD quality voice and additional features that customers want," said Tony Melone, chief technology officer at Verizon. "We're pleased to be working with AT&T as our first interoperating carrier, and we look forward to working with other operators as VoLTE continues to grow."

"Interoperability of VoLTE between wireless carriers is crucial to a positive customer experience," said Krish Prabhu, president, AT&T Labs and Chief Technology Officer, AT&T.  "Customers expect to be able to connect anywhere, anytime– and as LTE technology continues to evolve, it's imperative that we provide a seamless experience between carriers. We are pleased to work with Verizon on this initiative.  We continue to work with others in the industry on similar collaborative arrangements and hope to see similar collaboration across the industry in the near future."

Verizon introduced its Advanced Calling 1.0 services across the United States in September, and will continue to make Advanced Calling-capable smartphones available to its customers, further expanding the reach of the technology.

AT&T introduced VoLTE services in its initial markets earlier this year, and will continue to expand to more devices and more markets across the United States.
