[Freeswitch-users] T.30 faxing - V.27ter

[Tihomir Culjaga]

Hi,

i got an issue with faxing between a fax machine and FreeSWITCH T.30
protocol.

I'm able to send and get faxes everywhere except to this machine.
The fax machine uses V.27ter protocol at 4800 and no ECM.
faxing from a different fax machine works perfectly but not when i send it
from FS.

FS logs are here: https://pastebin.freeswitch.org/24139

I extracted audio
 and tried to decode it with fax_decode ( from spends/tests ) and it fails
to decode as well.
Also, i tried to decode the audio between two fax machines when the fax
went ok and it fax_decode fails on this one as well.

fax_decode logs:
https://pastebin.freeswitch.org/24140


so maybe we have an issue with V.27ter perhaps.

can anyone look say a bit more on this issue ?

P.S.: FreeSWITCH Version 1.4.18+git~20150312T185523Z~4eed221b69~32bit (git
4eed221 2015-03-12 18:55:23Z 32bit)


regards,
Tihomir.
