[Kamailio-Users] Presence_Dialoginfo versioning
by kamailio.org＠spam.lublink.net 21 Dec '09

21 Dec '09

Hey, I have noticed that the XML body of the dialog messages contains a version attribute. The server is counting the versions using the latest subscription as a reference point, and the phone is counting the versions from the first subscription ( at reboot ). Which is the correct way to count these versions? Consider : 10:00 Subscription 10:05 Notification version 1 10:35 Notification version 2 11:01 Subscription 11:05 Notification version X Is X = 3 because it is the third notification or 1 because it is the first after the last subscription? If it's version 1, it could confuse the phone cause a notification that is sent at the same time as the notification would have a confusing version. On the other hand, each subscription, has it's own versioning, so would it not logically follow that the different subscriptions for the same device have seperate versioning? From my phone : BLF Notify received for line: 3 has older version: 3 last version:135 To confirm my theory, I redialed the number 133 times, and once the version number had run up to 136, the lights started flashing again. Is this a bug in Grandstream, Kamailio, or perhaps an RFC which was unclear? Thanks, David

[Kamailio-Users] log not showing when using uac_replace_from( ) function
by Robert R 19 Dec '09

19 Dec '09

Hi, I simply trying to modify URI and FROM headers as follow. tcpdump packet capture shows the values are changed for both URI and FROM headers. However, the syslog only shows the new value for URI and not for FROM header. How can I verify new value in FROM header in the log file? # main request routing logic route { $rU = avp(i:1); $rd = avp(i:2); .... uac_replace_from("$avp(i:3)"); xlog ("fu after perl: $fu"); xlog ("ru after perl: $ru"); ... } Thanks, Rob

[Kamailio-Users] Transparent bridge mode
by Sungjoo Kim 17 Dec '09

17 Dec '09

Hello All, I'm trying to setup a test scenario, where i have Kamailio and rtpproxy running on one CentOS box(server1) and asterisk running on another CentOS box(server2). Server1 has 2 NIC's installed, eth0 connected to the WAN and eth1 connected to Server2 in a bridge mode. I will be modifying rtpproxy to intercept data flowing to Server2 and process them before i let them continue to flow along their original path. Server2 has to have a Public IP. For this i am having to use 4 Public IP's- eth0,eth1 and bridge br0 on Server1 and eth0 on Server2. Is there an alternate way of doing this ? Do you suspect there will be a problem with setting things up this way while trying to use rtpproxy to intercept data. Thanks and regards, Vikram.

[Kamailio-Users] Kamailio and RTPProxy
by Bruce McAlister 16 Dec '09

16 Dec '09

Hi All, I am trying to setup kamailio 1.5.3-notls for use with rtpproxy 1.2.1. I have a partially working setup, however, when I have a softphone configured behind nat it appears that rtpproxy is using the internal ip (prior to nat) to setup the sdp ports. I have rtpproxy configured in bridge mode as follows: rtpproxy -f -F -l public_ip/internal_ip -s udp:*:11211 I have kamailio's nathelper module setup as follows: modparam("nathelper", "rtpproxy_sock", "udp:internal_ip:11211") I then use a softphone (x-lite) behind a nat firewall (ip = 192.168.11.2) to establish a call, and the log of rtpproxy is as follows: INFO:handle_command: new session ZmRkNjRlNjM0NzExZjQ5MWUxYjllOTFhZWFmZGZkMjY., tag 8330585e;1 requested, type strong INFO:handle_command: new session on a port 52572 created, tag 8330585e;1 INFO:handle_command: pre-filling caller's address with 192.168.11.2:35498 INFO:handle_command: lookup on ports 52572/40380, session timer restarted INFO:handle_command: pre-filling callee's address with internal_ip:11250 INFO:handle_delete: forcefully deleting session 1 on ports 52572/40380 INFO:remove_session: RTP stats: 906 in from callee, 0 in from caller, 906 relayed, 0 dropped INFO:remove_session: RTCP stats: 3 in from callee, 0 in from caller, 3 relayed, 0 dropped INFO:remove_session: session on ports 52572/40380 is cleaned up In the log above it looks like rtpproxy is using 192.168.11.2:35498 as the remote ip/port combination to contact for the sdp session of the x-lite softphone. I would have thought that it would use the IP address that initial request was received from to establish this connection (via the fix_nated_contact() function). My route logic in kamailio is a slightly modified default configuration that is installed with kamailio : route{ . . . # NAT detection route(4); . . . route(1); } route[1]{ if (check_route_param("nat=yes")) { setbflag(6); } # if (isflagset(5) || isbflagset(6)) { route(5); # } /* example how to enable some additional event routes */ if (is_method("INVITE")) { #t_on_branch("1"); t_on_reply("1"); t_on_failure("1"); } if (!t_relay()) { sl_reply_error(); } exit; } route[4]{ force_rport(); if (nat_uac_test("19")) { if (method=="REGISTER") { fix_nated_register(); } else { fix_nated_contact(); } setflag(5); } return; } Would the "fix_nated_contact" function in the "nat detection" route not fix the contact before passing over the request to rtpproxy to establish the sdp session? route[5] { if (is_method("BYE")) { unforce_rtp_proxy(); } else if (is_method("INVITE")){ # force_rtp_proxy(); if(src_ip==internal_ip_of_media_server) force_rtp_proxy("ocfaei"); else force_rtp_proxy("ocfaie"); } if (!has_totag()) add_rr_param(";nat=yes"); return; } onreply_route[1] { xdbg("incoming reply\n"); # if ((isflagset(5) || isbflagset(6)) && status=~"(183)|(2[0-9][0-9])") { if (status=~"(183)|(2[0-9][0-9])") { # force_rtp_proxy(); if(src_ip == internal_ip_of_media_server) force_rtp_proxy("ocfaei"); else force_rtp_proxy("ocfaie"); } if (isbflagset(6)) { fix_nated_contact(); } } failure_route[1] { if (is_method("INVITE") && (isbflagset(6) || isflagset(5))) { unforce_rtp_proxy(); } if (t_was_cancelled()) { exit; } } Any pointers would be greatly appreciated. Thanks Bruce

Now I know that I'm doing also > sip_trace inserts in mysql sip_trace is writing big amount of data, this can make mysql do a lot of work. Try without it and see the difference. Also, doing acc to syslog brings some penalty if syslog is not configured in asyncronous mode (see my previous email). Cheers, Daniel -- Daniel-Constantin Mierla * http://www.asipto.com/
