Alright, I'm trying to get this straight.  You are able to dial an IAX peer
when the entry is in your iax.conf file, but not when you've taken it out
and replaced it with a realtime entry.

Lets try to isolate what the difference in the two entries could be if
there is one.  Can you provide 'iax2 show peer <peername> output for both
the working iax.conf entry, and then for the not working realtime entry.
