You'll want 1.6.13 or master, this bug was a pain in the butt to find and fix. /b On Thu, Dec 1, 2016 at 11:01 AM, Peter Steinbach <lists@telefaks.de> wrote:
Thanks,
by the way, we found out in further testing, when setting RTP ports to 65000+, this error went away.
But anyway, we will have to update/recompile Freeswitch.
Best regards Peter

Hello,
I have a strange error when proyy-media T38 faxes. Freeswitch is behind NAT (internal 192.168.12.248, external 5.10.xxx.yyy), other, receiving Server is also a Freeswitch
A connection is made via G.711A, we hear the machines negociating, then we receive a T.38 reinvite from the remote Freeswitch server. The local ATA 30@ reponds with T38 SDP, Freeswitch is passing it to the remote site (and there the error occurs). See error in bold:

Some background Info:
- Freeswitch runs in LXC environment - Freeswitch runs as non-priviledged user.
What is the cause of this? Maybe a problem with port 29544? But port 29544 was already previously used with G.711A.
