Routing between 2 domains
by kai.ohnacker＠cbc.de 27 Oct '15

27 Oct '15

Hello community, I work with Kamailio 4.2.0 which is placed between two networks (with two interfaces) and RTPproxy in bridge mode. The task from Kamailio is to handle the calls from internal networks to internal networks only on the internal Interface without bridging. For external networks vice versa. If the call comes from external to internal, then the RTPproxy should work in bridge mode and vice versa. I adapt the example with IPv4 and IPv6 routing, but this is not working for internal to external calls and vice versa (http://kb.asipto.com/kamailio:kamailio-mixed-ipv4-ipv6). Only external calls and only internal calls works. I think the cause of this behavior is the routing which I implemented to the RTPmanage part in the Kamailio config. The error message is given by the internal device. (call from external to internal) If I make a call from internal to external, the RTP stream is only in one direction. Internal Interface IP: 203.207.111.58 External Interface IP: 193.16.163.58 The RTPproxy config is: CONTROL_SOCK=udp:127.0.0.1:9000 EXTRA_OPTS="-l 203.207.111.58/193.16.163.58 -d WARN:LOG_LOCAL1" Kamailio.cfg: #!define INT_IP 10.96.0.0/14 #!define EXT_IP 193.0.0.0/8 # RTPProxy control and singaling updates for NAT traversal route[NATMANAGE] { #!ifdef WITH_NAT if (is_request()) { if(has_totag()) { if(check_route_param("nat=yes")) { setbflag(FLB_NATB); } } } if (!(isflagset(FLT_NATS) || isbflagset(FLB_NATB))) return; # rtpproxy_manage("co"); # Start Test routing if((src_ip==INT_IP && dst_ip==EXT_IP)){ rtpproxy_manage("cowie"); } if((src_ip==EXT_IP && dst_ip==INT_IP)){ rtpproxy_manage("cowei"); } if (is_request()) { if (!has_totag()) { if(t_is_branch_route()) { add_rr_param(";nat=yes"); } } } if (is_reply()) { if(isbflagset(FLB_NATB)) { if(is_first_hop()) set_contact_alias(); } } #!endif return; } Can someone help me with the right routing? Do you need some more debugging information? Cheers, Kai

Kamailio start up fails with strange IO Error on RHEL 7.1
by M S 26 Oct '15

26 Oct '15

Hi, I have been trying to setup Kamailio v4.3.3 rev. e275bc on RHEL 7.1 64bit. It has been very difficult to resolve all dependencies initially due to RHEL's extremely limited repositories and libraries support, but nevertheless I am finally able to successfully compile kamailio with all essential modules on it. However, now kamailio fails to start up and gives this strange error, -- 36(3335) CRITICAL: <core> [io_wait.c:526]: init_io_wait(): could not alloc epoll array 36(3335) CRITICAL: <core> [tcp_main.c:4523]: tcp_main_loop(): exiting... 0(3250) ALERT: <core> [main.c:725]: handle_sigs(): child process 3335 exited normally, status=255 0(3250) INFO: <core> [main.c:743]: handle_sigs(): terminating due to SIGCHLD -- I have never seem this error before nor i can find any info related to it anywhere on internet. So, i doubt it is due to any missing dependency. Any idea what may be the cause of this? Thank you.

Unable to Update Headers in failure route which were build in request route
by Sunil More 26 Oct '15

26 Oct '15

Hi All, I am trying to have a failover route where if a initial relay fails , i can forward the same request to a second provider. I am using a certain set of headers that help to authenticate over my providers. I am trying to update those headers. However update and removal both fail. The headers are still present. Please help me understand if i am wrong. Here's the code. ..... route(GET_CREDENTIALS); } remove_hf_re("X-*"); append_hf("X-Src-IP: Trusted\r\n", "Call-ID"); append_hf("X-Identity: $hdr(X-Calling-User)\r\n", "Call-ID"); append_hf("X-Auth-ID: $avp(siptrunk_username)\r\n", "Call-ID"); $avp(realm) = $fd; $rd = $avp(siptrunk_domain); $var(duri) = "sip:"+$rU+"@"+$avp(siptrunk_proxy); $du = $var(duri); t_on_failure("UAC_AUTH"); if(!t_relay()) { sl_reply_error(); exit; } } failure_route[UAC_AUTH] { if(t_check_status("(4|5)[0|8][0|2|3|4|6|8]")){ xlog("L_INFO","failover testing"); revert_uri(); route(FAILOVER); } if (t_check_status("40[17]")) { xlog("got challenged \n"); uac_auth(); xlog("L_INFO", "Return code is $retcode"); $rd = $avp(siptrunk_proxy); t_on_failure("UAC_AUTH"); t_relay(); } } route[FAILOVER]{ xlog("L_INFO","doing failover now.. "); if($avp(failover_routing_id)!=$null) { $avp(outbound_routing_id)=$avp(failover_routing_id); xlog("L_INFO","Failover carrier credentials are.."); route(GET_CREDENTIALS); #not adding headers now remove_hf_re("X-*"); append_hf("X-Src-IP: Trusted\r\n", "Call-ID"); append_hf("X-Identity: $hdr(X-Calling-User)\r\n", "Call-ID"); append_hf("X-Auth-ID: $avp(siptrunk_username)\r\n", "Call-ID"); $avp(realm) = $fd; $rd = $avp(siptrunk_proxy); $var(duri) = "sip:"+$rU+"@"+$avp(siptrunk_proxy); $du = $var(duri); xlog("L_INFO","Destination Uri from failover is : $du"); t_on_failure("UAC_AUTH2"); if(!t_relay()) { sl_reply_error(); exit; } exit; } } failure_route[UAC_AUTH2] { if(t_check_status("(4|5)[0|8][0|2|3|4|6|8]")){ xlog("L_INFO","Failover failed. cancelled call "); exit; } if (t_check_status("40[17]")) { xlog("got challenged \n"); uac_auth(); xlog("L_INFO", "Return code is $retcode"); $rd = $avp(siptrunk_proxy); t_relay(); } exit; } Thanking You, Sunil More

issue with sending "delete" to rtpengine for cancelled branch
by Vasiliy Ganchev 26 Oct '15

26 Oct '15

Hi folk! Have an issue, and do not see the obvious way how to solve it, maybe i'm missing something. The call scenario: UA-A (hard phone, no rtpengine) call ->> UA-B (has 2 registration: hard phone (no rtpengine) and WebRTC based web phone (here the rtpengine is called, in branch_route)) When Kamailio fork call to UA-B, for the branch with WebRTC UA, I do rtpengine_manage (rtpengine receive command "offer" and allocate 4 ports). If UA-B answer via hard phone, Kamailio Cancel branch to WebRTC phone, and here I need to do rtpengine_manage (to send "delete" command to rtpengine). But as I see Kamailio CANCEL all nonanswered branches automatically (I see no place where to call rtpengine_delete) Any suggestion how to cope with such issue? cheers! -- View this message in context: http://sip-router.1086192.n5.nabble.com/issue-with-sending-delete-to-rtpeng… Sent from the Users mailing list archive at Nabble.com.

kamctl rtpproxy nh_show_rtpp not working
by amar Smart Telecom 25 Oct '15

25 Oct '15

Dear all, I have installed Kamailio and Rtpproxy. Following is the process (ps) info: "kamailio 648 1 0 Oct08 ? 00:00:05 /usr/bin/rtpproxy -s udp:127.0.0.1 7722 -u kamailio kamailio -p /var/run/rtpproxy/rtpproxy.pid -l 192.168.58.25" But when I give command: " kamctl mi nh_show_rtpp" it returns following: "500 command 'nh_show_rtpp' not available" What could be the problem? Thanks, Amar.
