Re: [SR-Users] Integration with multiple MS Teams instances

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 Au=RSA Enc=AESGCM(256) Mac=AEAD ct_wq_size: 0 enc_rd_buf: 0 flags: 2 state: established}{ id: 3 timeout: 0 src_ip: 52.114.75.24 src_port: 6272 dst_ip: 172.16.30.206 dst_port: 5063 cipher: AES256-GCM-SHA384 TLSv1.2 Kx=RSA Au=RSA Enc=AESGCM(256) Mac=AEAD ct_wq_size: 0 enc_rd_buf: 0 flags: 2 state: established}{ id: 4 timeout: 581 src_ip: 52.114.75.24 src_port: 6273 dst_ip: 172.16.30.206 dst_port: 5063 cipher: AES256-GCM-SHA384 TLSv1.2 Kx=RSA Au=RSA Enc=AESGCM(256) Mac=AEAD ct_wq_size: 0 enc_rd_buf: 0 flags: 2 state: established* *} * Thank you!
