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.<br><br><div class="gmail_quote">

I've been trying in vein to get T.38 faxing to work properly.<br>
<br>
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.<br>
<br>
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.<br>
<br>
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...<br>
