[Freeswitch-users] Unable to TXFAX, but receiving is OK. Always result (49)

[Mitch Capper]

Faxing is a B to try and get it to work reliably over VOIP.  I have
added a troubleshooting section at:
http://wiki.freeswitch.com/wiki/Mod_spandsp#Troubleshooting  with what
I have found.  It may help to track down the problem.
