Voice and SMS over LTE

VoLGA Forum Comments on One Voice

UPDATE:

The VoLGA Forum is updating (improving?) its statement on One Voice.  Check back soon...

It appears that the VoLGA Forum has quietly posted a document that talks about the relationship between VoLGA and One Voice. 

The primary message:  VoLGA is the best interim solution for voice over LTE.  It lays out a viable path to IMS telephony. 

One Voice is really an important step in clarifying IMS voice.  The One Voice initiative is like the RCS initiative, which sought to simplify IMS data services. 

One Voice doesn't tell operators how to do voice over LTE, it just gets the ball rolling for operators wanting to do IMS voice.  But given this is step one, and covers the bare minimum for making a phone call, it's clear there is plenty of work to be done. 

Someone mentioned to me that One Voice, as the lowest common denominator, doesn't address even basic capabilities like pre-paid.  Can anyone comment?

One voice to rule them all

Industry Analyst Dean Bubley recently weighed in on the “One Voice” announcement. His take: excellent first step at boiling down IMS “…to the minimum set of requirements for basic telephony to work.”

Playing out the idea that One Voice attempts to establish the functionality of basic telephony means that this is a first step in the long evolution to a commercially viable IMS voice solution commensurate with GSM (ie what subscribers expect from mobile voice).

Therefore, we concur with Mr. Bubley’s assessment that One Voice isn’t going to happen “ubiquitously” or “overnight.” "It's an important step, but it isn't the whole journey," he writes, and reiterates "there is still likely to be a need for an interim solution for several years."

I can only assume then, his reference to VoLGA being Frodo in a Lord of the Rings analogy implies that VoLGA is on the side of good and righteousness. Whereas CS Fallback, the Gollum in this situation, is the less optimal route to voice over LTE.
