Hi all,
I think I have this all quite good now. I do have the issue though that when
the remote party hangs up a call we aren't sent the BYE. I'm guessing this is
something to do with either the Record-Route or a Via header.
I don't think it's the Via because the responses from our ITSP come back with
something like this for the opensips line:
Via: SIP/2.0/UDP
192.168.52.1;branch=z9hG4bKcd53.5599c4a7.0;received=203.31.111.19;rport=5060
indicating that they are dealing with it. And I've tried changing the Via
header for opensips with this code but I think it is created late in the
process as it is never triggered:
if ( search("Via: SIP/2\.0/UDP 192\.168\.52\.1;") ) {
xlog("Correcting router's Via header...\n");
replace_all("Via: SIP/2\.0/UDP 192\.168\.52\.1;", "Via:
SIP/2.0/UDP 203.31.111.19;")
}
If I try to use record_route() it breaks everything as then opensips seems to
loose track of the session and doesn't even respond to the ACKs when the
session is created and then our ITSP hangs up 30 seconds later.
So again, any pointers greatly appreciated. And here is our config file as it
currently stands:
debug=3
log_stderror=no
log_facility=LOG_LOCAL0
fork=yes
children=4
/* uncomment the following lines to enable debugging */
#debug=6

#disable_dns_blacklist=no
#dns_try_ipv6=yes
auto_aliases=no
