Verizon, AT&T Working On Intercarrier VoLTE
Nov 3, 2014, 1:25 PM by Eric M. Zeman
Verizon Wireless and AT&T today said the companies are working together to make interoperable VoLTE calls a reality. Both carriers offer VoLTE to their subscribers, but those calls can only pass between two VoLTE-enabled devices covered by an LTE network run by the same carrier. In other words, Verizon customers can only call Verizon customers via VolTE and AT&T customers can only call AT&T customers. Engineers from both companies are working to create a set of requirements needed and then plan to move to field trials before a full deployment. Once VoLTE calls are interoperable between the two carriers, they'll work on other services, such as video calls and rich messaging. The two said customers can expect to see VoLTE interoperability for voice calls between Verizon and AT&T in 2015. T-Mobile also offers VoLTE to its customers, but it appears as though the Uncarrier has been left out of this partnership for now.
