I'm still struggling to figure out what my problem is and how to resolve it. If anyone has a moment to check this out I'd really appreciate it. I've also posted another set of logs, this time one from each server, in which I'm trying to call a conference extension on 10.15.100.10 from a Polycom endpoint registered to 10.15.100.20: Polycom IP650 >>> FreeSWITCH Server "A" >>> FreeSWITCH Server "B" Log from FreeSWITCH server "A": http://pastebin.freeswitch.org/17776 Log from FreeSWITCH server "B": http://pastebin.freeswitch.org/17775 What's worse is I'm able to reproduce this problem on nearly every call. Thanks again for your help. ~Brian On Wed, Oct 26, 2011 at 8:03 PM, Brian Wiese < brian.wiese.freeswitch@gmail.com> wrote:

Hello again everyone!

I'm getting a strange result when calling from a Polycom endpoint on FS server "A" to FS server "B": About one out of ten calls won't complete with the error "SIP/2.0 500 No session set by user". If I immediately redial the number again it works.

Here's my log: http://pastebin.freeswitch.org/17622 Note the response to the endpoint from server "A" on line 452.

Important IP addresses: Polycom endpoint: 10.15.100.250 Server "A": 10.15.100.20 Server "B": 10.15.100.10

I'm on the latest revision (git-2f786a0 2011-10-26 12-57-59 -0500) as well.

I appreciate your help.
