Hi all,
I've added advertised_address="203.31.111.19" to my config which has corrected
the Via header but it hasn't corrected my problem.
I also have added
record_route_preset("203.31.111.19");
when it gets an INVITE and this has helped but not fixed the problem. With it
in place and using the following code:
if ( ! t_check_trans() ) {
xlog("ERROR: NOT in a transaction:\n");
xlog("$mb");
}
When the remote party hangs up first I get lots of these until the ITSP gives
up:
ERROR: NOT in a transaction:

So it seems that opensips has lost track of the transaction at this point and
doesn't know where to send this on to.
