Verizon, T-Mobile, and AT&T are all offering LTE high definition voice and are starting to be able to interoperate.

claims that someone at SigmaVOIP said that Verizon and T-Mobile are accepting SIP traffic with G.722.
Can Ooma's HD Voice interoperate with Verizon/T-Mobile's HD Voice? If this becomes a standard among the cell phone companies, it will raise people's expectations for phone calls in general.
This would also help out when connecting to other SIP systems. I know the phone system at my work (a major corporation) supports G.722 high definition voice.
This could make Ooma look very attractive to customers if they also support it, and, conversely, look bad if they don't. So If you don't support it yet, I certainly hope you are working on it.
