[Freeswitch-users] Polycom not sending INVITE

Esteemed FreeSWICH hackers,
I'm coming to you as I know you all have buckets of experience with
Polycom and I'm more likely to find clueful people here than anywhere
We've had a few users complain that nothing happens when they place
calls. They hit 'dial'... there's silence... then beeping that lets
them know the call failed.
Naturally, we started pulling SIP traces thinking the problem was on
the server side, but we quickly discovered there was NO SIP traffic.
We then assumed networking. Well, we traced it all the way back to the
LAN where where the phone resides. We're not even seeing Polycom
attempt to send an INVITE from behind the firewall. I haven't gone so
far as to put a hub directly in front of the phone, but I'm reasonably
sure that the INVITE never hits the wire.
For completeness I'm including our Polycom digit matching.
The phone registers and stays registered the whole time. I also have
FreeSWITCH sending OPTIONS message every 30 secs or so.
Keep in mind that it works 90% of the time :/
Has anyone see anything like this before? Thanks for your insights!
