[Asterisk-Users] Sip clients not longer registering

Hi,

We have been using Asterisk since version 0.9x with little or no 
problems.  However, for an unknow reasons, our sip clients can nolonger 
register.  We updated to Asterisk 1.0.2 hoping that would solve the 
problem, but no luck.

Here is the entry from sip.conf for one of our clients:

[10012200]
host=dynamic
nat=yes
type=friend
mailbox=220 at 1001
username=10012200
secret=XXXXXXXX
context=1001
port=5060
quality=1000
dtmfmode=rfc2833
canreinvite=no
callerid="Muffin Man" <12223334444>
disallow=all
allow=g729

The settings have been check in the sip client (a gs 486) and they 
match.  Below is a couple of sip sessions from when the user device 
attempts to register:

The Asterisk server has a public ip (the above ips have been changed 
from actual values).  The client is behind a firewall using nat.  Up 
until this registration problem, nat never posed a problem.

Any suggestions?  So far we have not been able to identify any external 
problems (firewall, os, hardware, etc) that maybe causing this problem.
