[Freeswitch-users] Faxing via FreeSWITCH documentation

Sat Apr 14 01:06:33 MSD 2012

Sorry to hop into this conversation, but sice the subject is fax...

Brian,

You recomended  api_hangup_hook and that is currently what I'm using, I
tried execute_on_fax_success as it seemed more apropriate but I can't get
it to work properly. I'm still debuging but it seems to work only with
small faxes...

Have you tried execute_on_fax_success? Did it work for you?
