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 else :) 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. <digitmap dialplan.digitmap="911|011xxx.T|[2-9]xxxxxxxxx|1[2-9]xxxxxxxxx|[2-9]xxxxxxT|xxxT|xxxxT" dialplan.digitmap.timeOut="1|4|3|3|3|3|3" /> 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! Best, Gabe
