[Freeswitch-dev] t38

[François Delawarde]

Looks pretty cool, will try that!

A few more questions:
- How does it work (more or less)?
- Will normal bridges (no fax) work when t38_gateway app is called?
- Can it fallback to audio fax if the peer does not support t38?
- In passthru case, what happens if t38_passthru is not defined and the
peer reinvites with t38 (any reason for having to set t38_passthru?)?

Thanks,
François.
