T.38 Faxing - at a loss...
I've been trying in vein to get T.38 faxing to work properly. My provider is VOIP Innovations and my ATA is an EdgeWater 200EW (also tried a Grandstream HT-502) all of which support T.38. I have read the wiki about a thousand times and tried every combination of parameters in my dialplan that I can think of. I have the latest version of Freeswitch (built from git repo just today) and everything else works like a charm. What info should I post so maybe someone out there can give me some ideas? Like I said, I've tried about everything I can think of - even enabling t38_passthru = true on each individual call. Any ideas at all? Anyone using this provider and having T.38 work? I'm pretty desperate here and would even be willing to pay for an answer...
Hi Paige, As you've discovered, faxing is a beast! Let's start with a couple of questions: 1) What are you trying to accomplish? I'm guessing you're using FreeSWITCH as a PBX/SBC between your provider and your T.38 capable endpoints. 2) Does VoIP Innovations claim T.38 support for every call, every route, and every DID? In addition to answering these questions, could you post console output for the type(s) of calls you're attempting? You can post them to http://pastebin.freeswitch.org AFTER you enable "sofia global siptrace on". That should help us get started.

First, try to catche RE-INVITE with, for example, ngrep -d eth0 -q -W byline -i t38 host <ITSP PROXY>. End debug udptl flow with tshark -R t38 or tcpdump -s0 and then analyze with wireshark. 2012/1/14 Paige Sullivan <psullivan@concerttelecom.com>
