[Freeswitch-users] Fax on Sangoma

[Anita Hall]

Hi

The dialplan just sends the control to a python script over ESL which gives
rxfax(filename.tiff)

I have tried giving the rxfax() command in the dialplan itself with similar
results. Many calls drop prematuresly and a good many fail to receive DCS
after permitted retries.


regards,
Anita
