No, we do not need to upgrade wireless carriers. The only people really
affected are the SIP trunking providers, and they are also often the slowest
in introducing new features.

What I meant that by supporting SIP/G.711 we get an a existing, cost
effective way to access 5 billion wireless subscribers, as well as 500M
Skype subscribers, millions of corporate customers. Calling using SIP/G.711
through a SIP trunk provider is not only about wireline PSTN, it is about a
much larger universe of people.
