asterisk users - Feb 2006 - Asterisk 1.2.4 (behind NAT) IAX registration "Refresh 0" problem

Hi all,

I've had a strange problem this morning and I know someone who has 
reported exactly this problem to me too last week: -

I've setup a new server running Asterisk 1.2.4.  Currently there is no 
Zaptel hardware install (but there will be soon).  This server is behind 
a NAT router on an DSL line.

The remote IAX server on the Internet (which handles the call 
termination / origin) is setup with a "friend" entry on the new
server.

Whats happening is that the new * server does seem to register but "iax2 
show registry" gives:


*CLI> iax2 show registry
Host                  Username    Perceived             Refresh  State
212.147.134.3:4569    185         83.71.19.213:51951          0  Registered


That "0" for the "Refresh" is weird I think.  And, after
about 1 minute,
the new server stops receiving calls from the remote [Internet] IAX 
server - when the Internet IAX server tries to make the call to the new 
server it fails with "dial_exec: Unable to create channel of type 
'IAX2'" for that IAX2 dial command.

I do have other * servers (older than 1.2.4) that are registered just 
fine so I'm not sure if its to do with the newer version?

Has anyone else come across this?

Thanks very much,

Derek
