Verizon and AT&T working to allow VoLTE calls across networks

Verizon and AT&T announced yesterday that they are going to enable VoLTE-to-VoLTE connections between Verizon Wireless and AT&T customers in 2015.

VoLTE is a technology that lets people make voice calls and HD video calls over LTE. Its advantage is the faster speeds compared to those of the regular network. Some of the carriers like AT&T, T-Mobile and Verizon have already started providing the service, but limited to calls only within the network.

Currently, to make a call using Verizon's VoLTE service both parties on a call need to have a VoLTE-enabled Verizon smartphone. AT&T's VoLTE-enabled HD Voice service allows customers to make HD Voice calls with other AT&T customers using AT&T HD Voice-capable devices within AT&T HD Voice coverage areas.

"Customers use their smartphones to connect with friends, family and colleagues across service providers and around the world. 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."
