AT&T and Verizon Wireless have begun allowing some customers to place VoLTE calls to one another. The carriers' deployment of interoperable VoLTE is woefully behind schedule. AT&T and Verizon first promised to launch the improved calling by the end of 2015, but only got as far as limited trials. "Currently, we are working with Verizon to allow our customers to enjoy that clear audio quality and video calling features when placing VoLTE calls to Verizon customers and vice versa," said an AT&T spokesperson to Fierce Wireless. "In December, we saw the first VoLTE exchange between our customers and Verizon's in limited, select areas. We're working with others on this same feature, too." AT&T didn't say which markets support interoperable VoLTE, and Verizon did not comment on the deployment at all. There's no word if or when interoperable VoLTE will expand to a greater number of AT&T and Verizon customers. VoLTE requires both the caller and recipient to have compatible handsets and LTE coverage in order to function properly. VoLTE paves the way for HD voice calling, as well as RCS-based services, such as rich messaging and video calls.

Huge difference in quality too.

In central NY, we've had the HD calling (VoLTE) for a while now for AT&T. It is a major leap in clarity. With my hearing condition not the way it used to be, I've been able to hear people as if they were standing next to me. Can't wait until this is an industry standard.
