James, Just to add to Alexey's last comment, if your SBC *is* changing the transport from UDP to TLS, then you must ensure the correct socket is used on the SBC when it is sending requests to the Teams Proxy: force_send_socket(tls:137.117.136.143:5091);
You may also find it helpful to add " AS sbc.ip-sentinel.com:5091" on the end of your tls listen statement John Quick Smartvox Limited Web: www.smartvox.co.uk _______________________________________________ Users mailing list Users@lists.opensips.org http://lists.opensips.org/cgi-bin/mailman/listinfo/users
