[OpenSIPS-Users] rewriting transactional responses

[Jeff Pyle]

Hi Bogdan,

After some experimentation that's what I've discovered.  Much of the time
Opensips contines to resend whatever t_reply() sends even after receiving
the ACK from Asterisk (UAC).  I upgraded Asterisk to 1.4.23.1 (almost
current) and those retransmissions seem to have stopped.

Apparently it wasn't Opensips at all.  Imagine that.


Thanks,
Jeff
