Hello Daniel!
Thank you for the suggestion. Unfortunately adding the
"tcp_connection_match=1" did not made a difference. Kamailio found other
connection to the same peer and used it instead:
*<core> [core/tcp_main.c:1610]: _tcpconn_find(): found connection by peer
address (id: 2)*
Also, it looks like the answer is in this comment:
https://github.com/kamailio/kamailio/blob/master/src/core/tcp_main.c#L1563.
And below are active tls connections for the previous trunk. Is there a way
to add an additional field like a "tag" that could be used in peer matching
as well? Otherwise, I guess the only option I have is to run separate
instances of Kamailio with a very basic configuration for each MS Teams
connection.
*# kamcmd tls.list{ id: 2 timeout: 0 src_ip:
52.114.75.24 src_port: 5061 dst_ip: 172.16.30.206
dst_port: 0 cipher: ECDHE-RSA-AES256-GCM-SHA384 TLSv1.2 Kx=ECDH

*} *
Thank you!
