Support for the AMR-WB codec for HD Voice on T-Mobile

[nickderobertis]

Hello, thanks for your great work on this sytem.

I am wondering if we can add AMR-WB codec support. This seems to be the codec used by T-mobile for HD voice. I've been unable to get HD voice working on any call yet but my phone is T-mobile.

I saw the list of supported codecs here (G722, G711U) so that's why I assumed AMR-WB has not been implemented yet.

That's correct, for now we plan to fix G722 first, then add OPUS and probably G729. I think once we get G722 working correctly, adding new codecs would be pretty simple. But no ETA for now.
