Re: [SR-Users] Kamailio like SBC with Teams

The tutorial is pretty clear: You need to add the Contact header only for OPTIONS pings. You need to use the proper Record-Route headers based on the direction of the call. There's no out of the box solution because each setup is different. If you understand how loose routing works in SIP, then you know how to adjust the config to use record_route_preset(), just as explained in the tutorial. There is also an example of an INVITE that has the right Record-Route headers in the tutorial. You can choose to use the FQDN for the Record-Route header facing MS and the IP for the Record-Route header facing the carrier or use the FQDN for both Record-Route headers (just like in the tutorialexample). Alternatively, one can try to advertise the FQDN in the listen directive in the config and then the Record-Route headers should be populated automatically.

This way you will get sip debug decrypted. &lt;sipuser404(a)gmail.com&gt; mess with Kamailio, mainly to set it up as SBC against Teams, in this case. in the Kamailio I see: [ip_addr.c:243]: print_ip(): tcpconn_new: new tcp connection: 52.114.7.24 [tcp_main.c:1073]: tcpconn_new(): tcpconn_new: on port 4160, type 3 [tcp_main.c:1382]: tcpconn_add(): tcpconn_add: hashes: 171:1857:1187, 30 [io_wait.h:388]: io_watch_add(): DBG: io_watch_add(0xa1f240, 23, 2, 0x7f90f2438f80), fd_no=17 [io_wait.h:610]: io_watch_del(): DBG: io_watch_del (0xa1f240, 23, -1, 0x0) fd_no=18 called [tcp_main.c:4219]: handle_tcpconn_ev(): tcp: DBG: sending to child, events 1 [tcp_main.c:3902]: send2child(): selected tcp worker 1 10(23159) for activity on [tls:SBC_IP:5061], 0x7f90f2438f80 [tcp_read.c:1507]: handle_io(): received n=8 con=0x7f90f2438f80, fd=9 [tls_server.c:184]: tls_complete_init(): Using TLS domain TLSs<default> [tls_domain.c:700]: sr_ssl_ctx_info_callback(): SSL handshake started [tcp_main.c:2516]: tcpconn_do_send(): tcp_send: sending...
