As reported by Kevin Fitchard at Telephony Online, it appears that a VoLGA trial system has been installed into T-Mobile’s lab.
Clearly this is an important step for VoLGA. With IMS telephony still some years away, VoLGA is arriving at the right time to provide a solution for voice over LTE.
Zahid Ghadialy at the 3G4G blog summarizes the issue nicely in his post titled “LTE definitely needed and coming next year… don’t mention voice and SMS please”. The momentum around VoLGA is building at the same time the ‘other’ option (CSFB) is being abandoned left and right.
