HI Anthony (et al), I have finally captured the failure with SIPTRACE enabled. See pastebin: http://pastebin.freeswitch.org/20342 I have tried to clip this down to just the one call. It is from "anonymous" . <4104850152>->+14108825019 in context from-trunk The first error I see is "nta: received 406 Not Acceptable for INVITE (37544793)" I have no idea what that means though. I can't figure out why these calls work many times and fail others. My best guess right now is that this is a capacity limitation of the NAT/ROUTER at their site. I think some of these phones in this ring group may be double NAT'ed just to make my life fun. Any diagnosis of these logs would be greatly appreciated.
