[Dundi] servers cannot determine codec to use when making a call via DUNDi

[Colin Caird]

Hi everyone,

I'm having a hard time getting a new DUNDi node added to a DUNDi
network I'm setting up.  Whenever I make a call I keep getting an
error where the codec to be used cannot be negotiated between the two
servers (error shown below).  I have checked and both dundi users have
allow=all (I also tried specifying specific codecs).  A quick search
online resulted in a forum posting about not putting the guest user at
the end of iax.conf, so that was changed, still not working though.
Anyone have any ideas?

Thanks,
Colin
