[asterisk-users] Is there a way to force a codec on an incoming sip uri call?

[Eric Chamberlain]

Hello,

I'd like to implement some public sip uri's that poeple can call into  
and get an echo test.  Is there a way to force a codec so that users  
can test various codecs?

Something like:

echo-test at example.com (negotiates whatever codec, is there a way to  
figure out what codec was negotiated and tell the user)
echo-test-g711 at example.com (forces g711)
echo-test-g729 at example.com (forces g729)
echo-test-gsm at example.com (forces gsm)
...
echo-test-ilbc at example.com (forces ilbc)
