[asterisk-users] Asterisk t38passthrough

[rcarvalho at iric.up.pt]

Assuming that the patch was applied correctly and that each context of sip.conf
and also [general] context have all those 3 parameters you mentioned above, try
to activate also the accept reinvites option in those contexts of sip.conf. Use
ethereal to try to see if communication fails in that second reinvite.

Regards,
Ricardo.
