[Freeswitch-users] WARNING T.30 Non-ECM carrier not found

[Brian West]

Why are you making someone press *7 to transfer to the rxfax?  You could
use fax detect and warp it over without bothering the user.  I would need
to see your spandsp.conf to see what settings you have, sounds like you've
disabled ECM and this endpoint doesn't support that possibly, But again
thats just me guessing based on the limited information.
