[Freeswitch-users] micrsoft voip plug in for fax

[Darcy]

Thanks, what actually happens is during the negotiation and t38 discovery, 
the freeswitch switches to the inside address, I just found this, so I need 
to see what is different that causes it to do that, it does start in the 
pcmu mode then switches to t38.  There is a setting that allows me to 
manually input 'public IP address of NAT' and when I do that it works.  I am 
going to do a pcap between the spa2102 and the voip plug in to see the 
difference.

So you are talking about using Faxback's VoIP plugin for Microsoft FAX
in T.38 mode, and sending from Microsoft FAX and scan? That should work
OK. Perhaps something has been altered in the negotiation in an
incompatible way. Can you get a pcap file of an exchange with the
Freeswitch server, and we can try to figure out what is going wrong.

If I remember rightly Faxback has a lot of compatibility problems,
because they try to start in T.38 mode, which a lot of VoIP systems
don't like. However, I might be remembering an old problem that went away.
