Brent,

Thank you veeeery much for replying. I thought the message went unseen but
found your reply when I went to look at the thread :)

You're absolutely right. Looks like the SIP client was messing up (or
something) when different codecs were used. I tried canreinvite=no and it
worked perfectly, but as you said, it's best to bypass Asterisk when talking
between clients on the same network. I tried a different IAX client and it
had no problems using different codecs (with canreinvite=yes) so all is
good.

Thanks again!
Gonzalo
