Sonus has a VAN (Controller)

A few weeks back, Sonus Networks announced that it had joined the VoLGA Forum. Keen UMA Today readers recall that the VoLGA is a voice over LTE technology based on the existing 3GPP GAN standards.

Joining a forum isn't that exciting, but there was a nugget in the release that I missed. In the announcement, Sonus actually announced that it’s MobilEdge product (part of its MobilEvolution strategy) can be used as a VoLGA Access Network Controller, or VAN-Controller.

Sonus MobilEvolution architecture supports joint interworking of packet and circuit-switched network elements, enabling mobile network operators to initially combine a circuit-switched core network for legacy services with an IP-based access and core network for multimedia services. The Sonus MobilEdge can be used as a VANC (VoLGA Access Network Controller) as defined through the VoLGA forum. The VoLGA forum has been set up to facilitate the delivery of voice and SMS services within the LTE environment from initial development.

I believe this is the first confirmed product announcement supporting VoLGA. It’s good to see vendors pledging support to the technology.
