That's going to be a tough thing to do... it's certainly not supposed to 
be in app_voicemail, it should not care at all about the channel 
supplying the data (or what the data is).

I don't think it makes sense to be in the recording function either; 
somehow the recording API needs to be able to tell the channel that it's 
about to start recording, so the channel can do what's needed.

Is this required for any use of that particular codec (regardless of 
whether SIP, IAX2, or otherwise) or is it SIP specific?
