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
never seen this before. Try cranking the logs way up on the polycom. Also, what phone model and firmware? On Feb 19, 2014, at 7:58 AM, Gabriel Gunderson <gabe@gundy.org> wrote:

Good call on the logs. It's a 550 and the fw is 3.x (don't recall and I'm not at the office). I'll report once I've done some more digging. Gabe
Gabriel, We had similar reports from our PolyCom 335 users. Someone pointed out that I had <param name="NDLB-force-rport" value="true"/> in my directory entries. Turns out Polycom does not support rport. As recommended, I changed it to the special case value for Polycom: <param name="NDLB-force-rport" value="safe"/> and we have had no more reports of problems. I must admit I do not know what rport is (I would love a 30 word or less explanation) or if it might be related to your problem. But, it sounds really familiar and we seem to have gotten past it with this change. Hope that helps, Sean -----Original Message----- From: freeswitch-users-bounces@lists.freeswitch.org [mailto:freeswitch-users-bounces@lists.freeswitch.org] On Behalf Of Gabriel Gunderson Sent: Wednesday, February 19, 2014 7:58 AM To: FreeSWITCH Users Subject: [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 else :) We've had a few users complain that nothing happens when they place calls.
