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.

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

Yes. I understand that. I am considering a case where

Hi,
Does Asterisk support wideband VoIP? Is there
support
for Speex 16 KHz?
What devices support this?
As I'm sure you know, if the call hits the PSTN it
will always be ulaw
or alaw and so will not be wideband. Wideband
codecs are only helpful
if the call IP end to end.
