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 ________________________________

I'll try the tcpdump and update you On Mar 9, 2010, at 10:13 AM, Robert Joly wrote: Francis, 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)? bob ________________________________ From: [email protected] [mailto:[email protected]] On Behalf Of Francis Tinio Sent: Tuesday, March 09, 2010 9:48 AM To: Tony Graziano Cc: sipx-users Subject: Re: [sipx-users] deployed new sipx server....3 phone extensions,only 1 is accessible inbound 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) On Mar 9, 2010, at 9:42 AM, Tony Graziano wrote: Oh, those phones are very old and at end 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.

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.
