[asterisk-users] wideband codec support

[Steve Totaro]

Peer 2 Peer SIP (or other protocol) is the future of telephony. 

Speex will work but you need to compile and install it separately from 
Asterisk (and before Asterisk) due to licensing issues with Digium.  Not 
sure why you would want to use speex but here is a good link on the wiki 
with additional info.  
http://www.voip-info.org/wiki/view/Asterisk+config+codecs.conf

I have only used it for very low bandwidth applications and satellite 
connections.  It increased latency but the audio was almost perfect 
where other codecs broke up so badly that a conversation was impossible.

Thanks,
Steve
