Look closely at the above four lines. In the "allow" statement, that
appears to be a zero. Change that to "allow". Also, I don't know 
which codecs the phone supports, but you might start playing with
 disallow=all
 allow=ulaw
and go from there.

If you look at /usr/src/asterisk/configs/iax.conf.sample, you'll 
find that dtmfmode=rfx2833 is not a valid iax statement. Plus its
spelled wrong (its rfc2833). Remove it, but add it into your sip.conf
if you're going to play with sip.

Here is the key:     ^^^^^^^^^^^^
That is telling you it can't find a compatible codec to allow the
call to complete. That's the basis for the comments above about the
allow=ulaw.

Note the above "IAX". I think that should be IAX2, so look in your
extensions.conf for a dial statement that looks like "Dial(IAX/"
and change it to "Dial(IAX2/".
