[asterisk-users] T38 re-invites issue

[Marek Soha]

Uf...

you are perfectly clean about that confusion...

Only thing I want to do, is to route "stream" out of local asterisk - to
connect final extension directly to "sender" - provider.
So what I can do if I need i.e:

1) canreinvite=yes AND send T38 faxes through the same trunk?

2) maybe canreinvite=no, but UDPTL routed outside local asterisk
(called canreinvite in normal RTP traffic)?

Yes and - many thanks Kevin for your perfect reply.
