VoLGA = 1, other VoLTE = 0


From Unstrung:

Deutsche Telekom Announced First Voice Calls over LTE with VoLGA. Deutsche Telekom announced today the world’s first voice call over LTE with excellent speech quality based on VoLGA (Voice over LTE via Generic Access) technology and two independent test environments.

Calls have been made between a test system, installed at Deutsche Telekom Headquarters in Bonn, Germany which is based on a VoLGA implementation of Kineto Wireless and a second totally independent system from Alcatel-Lucent, installed in their test center in Stuttgart, Germany. Both VoLGA-based Voice over LTE systems support inbound and outbound voice calling and SMS messaging between LTE-enabled devices and standard mobile and fixed telephones.

With this result Deutsche Telekom underlines the innovative leadership in the development of Next Generation Mobile Networks (NGMN), as it belongs to a series of tests through which the company consequently researches the capabilities of the potential NGMN technologies.

“Voice calling is an essential service for mobile operators. This demonstration is a key milestone towards establishing a future proof eco system and shows a cost efficient way for using voice over LTE”, stated Uwe Janssen, Senior Vice President of Core Networks. “The VoLGA test shows how operators could quickly and easily provide next generation voice services, re-using their existing core networks. At the same time this serves as a first step to prepare networks for the industry-agreed mid- and long-term solution for voice over LTE that will be based on IMS.”

In other related news from Fierce Wireless:

Ericsson has dropped its support for the VoLGA Forum, which promotes Voice over LTE via Generic Access, dealing a blow to the voice-over-LTE approach a little more than a month after the vendor signalled its enthusiasm for a different standard.

Erik Ekudden, Ericsson's vice president of technology and industry, said that when the VoLGA Forum was established earlier this year "we had the impression that VoLGA would become a global solution." However, "there are no signs that it [VoLGA] will be strongly supported" by mobile operators, he said in an interview with Unstrung.
