Hello asterisk-dev,
How hard would it be to put 16kHz codec support into asterisk? I mean =
full support -- voice mail, prompts, etc all in 16kHz. I have a SIP =
phone that supports G.722, but it always falls back to G.711 when =
talking to asterisk. It would be nice to take advantage of the full =
voice quality! My cursory browsing of the source code seems to indicate =
that the design may be centered around an 8kHz sample rate though -- not =
surprising, given the telephony orientation.
I've seen several products announced recently that use G.722 over sip =
(3Com, Alcatel, the new Grandstream 102D), so this would be nice to =
support with asterisk. So far, I'm using mine with Ser, but voicemail, =
ivr, etc. would be nice!
Cheers -- Don.
