Opensips 3.2 + Rtpengine +Topology hiding + Bridging under Debian Bullseye

App Opensips repo to sources lists apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 049AD65B echo "deb https://apt.opensips.org bullseye 3.2-releases" >/etc/apt/sources.list.d/opensips.list echo "deb https://apt.opensips.org bullseye cli-nightly" >/etc/apt/sources.list.d/opensips-cli.list Install opensips and its dependencies apt install opensips opensips-* Main route for the example, replace OPENSIPS_WAN_IP with your Opensips servers public IP address, replace OPENSIPS_LAN_IP with the Lan IP of Opensips. We route every call to an Asterisk server listening on REMOTE_ASTERISK_IP:PORT. All calls from Asterisk will be routed out to your outbound provider at YOUR_PROVIDER_IP:PORT. ####### Main routing Logic ######## route{ if(!has_totag() && is_method("INVITE")) { create_dialog(); topology_hiding("UC"); if ( $socket_in(ip) == "OPENSIPS_WAN_IP" ) { $var(direction) = "in-iface=wan out-iface=lan"; $var(whereto_send) = "REMOTE_ASTERISK_IP:PORT"; } if ( $socket_in(ip) == "OPENSIPS_LAN_IP" ) { $var(direction) = "in-iface=lan out-iface=wan"; $var(whereto_send) = "YOUR_PROVIDER_IP:PORT"; } $var(rtpengine_params) = $var(direction) + " replace-origin replace-session-connection"; if ( has_body("application/sdp") ) rtpengine_manage("$var(rtpengine_params)"); $du = "sip:" + $var(whereto_send); $ru = "sip:" + $rU + "@" + $var(whereto_send); route(RELAY); } if ( has_totag() ) { if ( is_method("ACK") && t_check_trans() ) { route(RELAY); } if ( topology_hiding_match() ) { if ( is_method("BYE") ) rtpengine_manage(); route(RELAY); } else send_reply(404,"Not found"); } if (is_method("CANCEL")) { if (t_check_trans()) { rtpengine_manage(); route(RELAY); } } send_reply(501,"$rm not implemented"); } routeRELAY] { if (!t_relay()) { send_reply(500,"Internal Error"); } exit; } onreply_route { if ( has_body("application/sdp") ) rtpengine_manage(); } Thats it, now you have installed Opensips 3.2 in a front of Asterisk that is listening on a private IP.Your suggestions are always welcome!
