[Freeswitch-users] Fax to an extension of B leg

[Brian West]

Review this, it may give you a road map
https://raw.githubusercontent.com/signalwire/freeswitch/master/scripts/perl/fax.cgi

The key here is ignore_early_media=true, you don't want to be in the txfax
app until the remote answers, because you are in a chicken egg scenario
where the fax will fail or t.38 will fail as it will attempt to do so
before the other party answers.
