[Freeswitch-users] txfax unexpected message received

[António Silva]

Hi Shaun,

Thanks for the reply.

Yes, mod_fax was merged into mod_spandsp. also i always try to use t38 
but in this case the gateway in front (an old old nortel cs2k) is worst 
than using t30.

I also read that old message but for what i could understand it was some 
echo issue but i don't think is the problem here i don't reach the 
training part..., i also sending the fax at lower speed... Also using 
this same trunk (similar path) with only t30 to other destinations works 
ok, so I'm think on some sort of incompatibility on the transmitted page 
size, training method or other reason i don't know..


Yes the full log was attached in the email, didn't show up to you?


I put it into pastebin:
