[SR-Users] geting $conid on outbound INVITE

[Marrold]

Hi David,

I've previously looked at $conid and I was under the impression it was only
available as the *source* connection ID for received messages, not the
destination connection ID. Some experiments confirmed this, although I
didn't dig too deeply into the code.

It's inferred in the docs
<https://www.kamailio.org/wiki/cookbooks/5.4.x/pseudovariables#conid_-_tcp_connection_id>
that it's only for messages arriving at Kamailio: "The TCP connection ID of
the connection the current message *arrived* on for TCP, TLS, WS, and WSS.
Set to $null for SCTP and UDP."

There is however tcp_get_conid
<https://www.kamailio.org/docs/modules/5.3.x/modules/tcpops.html#tcpops.f.tcp_get_conid>
available
in the TCPOPS module in 5.3 and up which will retrieve the destination
connection ID.

Cheers
