Difficult to tell without some feedback from the CLI. If you actually
copy/pasted the above config statements, I'm assuming you manually
added all those "~" at the front of each line. If they are actually
in your config, get rid of them.

The statement "jutterbuffer=no" should be jitterbuffer=no.

One thing you might try to at least eliminate possible problems is
to change iax.conf to disallow=all and allow=gsm only. Get rid of
the allow=ulaw and do another test. Might as well add trunk=no 
to this link as well. (Must stop and restart * after making these 
type changes.)

You might try 'iax2 debug' from the CLI on both machines and look at
the detail to see if you can spot any conflicts or problems.
