At first, VoLTE will be used to deliver "Rich Communications Services" (which look like something similar to what Voice over IP/Video over IP outfits offer today) rather than completely replacing narrowband voice. It will be awhile before Verizon is willing to commit to that, due in part to LTE outages in late 2011.
On the flip side is MetroPC, which has pushed VoLTE as hard as it could.
Then there's Sprint, which will stick to voice over 1x for the foreseeable future, but routes Direct Connect over IP. Sprint's latest DC incarnation seems quite similar to one facet of RCS over LTE.
One thing that we have forgotten is this may not be a pure win lose court case. If you read the FCC order you will note it is missing the appendices that would cover county by county spectrum screens yet they are mentioned in the table of contents. The ruling specifically tells the Wireless Telecommunications Bureau how to handle the Dish licenses but not the Sprint licenses which would be the next step. Likewise the DOJ never went to the next step of buying national advertisements to start the Tunney Act process. Basically the state AGs court case seems to have frozen or taken over these aspects. In smaller mergers these details are often handled by an administrative law judge.
Jumping off of my previous issue with VoLTE with Verizon customers. It seems like Sprint to Sprint HD voice works fine both for incoming and outgoing calls but with Verizon users, it won't activate unless I call the person. Incoming calls from Verizon sound horrible.
That would involve another lengthy merger proposal with the FCC and DOJ. Another 2 years wasted. A possible new administration... IDK.... don't like that idea. Who's going to teach them how to run a network? (LOL)... please don't say ....
