[Freeswitch-users] Fax 2 Email issue

Thu Dec 15 15:22:31 MSK 2016

can you try using ECM ?
also, try using a real fax machine instead of zoiper.

i never tried to send a fax with zoiper, what is it using, T.30 or T.38 ?

but, anyhow, what you are trying to do is a basic call flow that works out
of the box.

if you are using T.30, get a tcpdump/wireshark dump of your fax call,
extract the audio from it and try decoding it with fax_decode utility
included with spandsp. This will give you more details.

T.
