I was inquiring about the NAT that is fronting your remote phones (i.e.
the NAT in the remote office).  
 
Thank you for providing the tcpdump - I'm the designer of the remote
user NAT traversal feature on sipXecs so I have a vested interest in
understanding what is going wrong here.
 
When you do your tcpdump, please start it, then reboot all three phones
so that their registration process gets captured and then do a failing
ITSP->phone call followed by a failing phone->phone call.
 
Could you also please include a copy of
/etc/sipxpbx/nattraversalrules.xml?
 
Thanks in advance,
bob

        the sipx server is plugged in directly to our switch, no
firewall in between, also no NAT. that is what puzzles me.  there should
not be any issues with nat traversal on the server end. 

        I'll try the tcpdump and update you

                I think that the quickest path to understanding your
problem would be to provide either a sip trace as Scott requested or
provide a network trace by running tcpdump -n -nn -s 0 -i any -w
remote_user_problem.cap directly from your sipXecs.
                 
                What kind of router is at the remote location and did
you ensure that its SIP ALG was disabled (if supported)?

                        also, one thing I noticed is that when I first
configured the 1st extension, it was able to accept inbound calls.  But
once I provisioned the next 2 phones, only the last provisioned phone
was accepting calls and the 1st would now reflect as user offline
(although it still shows registered and can make outbound)

of life, they stopped being able to provide updates some time ago
because the resources were not on the devices to take the new code. I
would try with 550's or 650's and 3.1.3RevC and see if you have the same
issue.

                                ip500 cannot use firmware 2.1.3 and
below.  it cannot use any newer.  and 2.1.3 seems buggy that everytime i
use it, the icons do not show right so i'm using 2.1.2.

                                I'm running the latest stable of sipx.
4.0.4 I think.
                                
                                For polycom, it's ip500 and the latest
software and bootrom are buggy, so I downgraded 1 version down.  I don't
think the problem is with the firmware though.
