[OpenSIPS-Users] non-transactional 4XX messages

[Jason Yeh]

Tyler,

Yes, I have already thought the same thing. However that 403 SIP Message
didn't land there in the main routing block, yet through pcap traces I could
see the SIP Message being routed to the end-user client. I had this basic
log of every new messages routed to the main route, for example:

============
route {

# Simple Log

xlog("L_INFO", "#### M=$rm RURI=$ru F=$fu USR=$tU T=$tu IP=$si ID=$ci\n");

....
============

I don't see 403 message landed there.

I tried to add logic of something like this on main route:

============

# Detect if SIP/2.0 403 Message
if ( status == "403" ) {

xlog("got SIP 403");

}

============

Unfortunately, realized that the "status" reference of current message would
only work for the onreply route.... I'm sure there is reason for it, most
likely developers might can answer that.
