by Daniel Cardoso Alves 30 Dec '09

30 Dec '09

Hello... I have a SIP Redirect Serve with a kamailio and it works fine with others system(NexTone, Asterisk, etc), but I have a problem with a SIP redirect client with Kamailio. I am using http://kamailio.org/docs/modules/1.5.x/uac_redirect.html to try manipulate the 3xx message. I would like to send one destiny at a time, but the get_redirects("10:2","redirect") send only 2 contacts and at teh same time. I get from my SIP Redirect Server this message: SIP/2.0 301 Moved Permanently..Via: SIP/2.0/UDP 2XX.XX.XXX.XXX:5080;branch=z9hG4bK633e.a3e32ff2.0;rport=5080;received=2XX.XX.XXX.XXX..Via : SIP/2.0/UDP 192.168.0.133:7191;received=201.XX.X.XXX;branch=z9hG4bK-d87543-254f7f3a1058e232-1--d87543-;rport=7191..To: <sip:05433330000 @2XX.XX.XXX.XXX:5080>;tag=609b19d62bd6886602a6c902875525b0.c8b2..From: "1938"<sip:1938@2XX.XX.XXX.XXX:5080>;tag=187fec3c..Call-ID: 4959bc 623e556571@ZGVzZW4tcGMtMDguZ292b2lwLmNvbS5icg....CSeq: 1 INVITE..Contact: sip:55341#5433330000@192.168.0.2, q=1, sip:123#5433330000@1 92.168.0.3, q=2, sip:55341#5433330000@192.168.0.4, q=3, sip:55341#5433330000@192.168.0.5, sip:55341#5433330000@192.168.0.6, sip:553 41#5433330000(a)192.168.0.7, sip:55341#5433330000@192.168.0.8, sip:55341#5433330000@192.168.0.9, sip:55341#5433330000@192.168.0.10. .Server: Test Redirect..Content-Length: 0....

Better than giving you the solution, try to guest it ... Think a little ... what have in common a REQUEST from UAC A to UAC B if they are behing THE SAME NAT ROUTER ? -- Raúl Alexis Betancor Santana Dimensión Virtual ____________________________________________ Dear Mr. Santana Thanks for trying to help. oh, I guess, they've got the same IP-Address ;-) I found this code-snip in : dokuwiki/doku.php/examples:caller-callee-behind-same-nat ______________________________________ else if ( isflagset(2) and isflagset(3) ) { log(1, "Both Clients are behind NAT"); # Store the destination domain into an AVP avp_printf("$avp(i:450)", "$dd"); if ( avp_check("i:450", "eq/$src_ip/g") ) { xlog("L_INFO", "2 Clients Behind the Same NAT - Disabling Mediaproxy"); # Do not use mediaproxy as the clients seem to be behind the same NAT resetflag(2); resetflag(3); } } _______________________________________ But this Code-snip contains many mistakes so I changed it to : _______________________________________ if ( isflagset(5) and isbflagset(6) ) { lookup("location"); log(1, "Both Clients are behind NAT"); # Store the destination domain into an AVP avp_printf("$avp(i:450)", "$dd"); if ( avp_check("$avp(i:450)", "eq/$src_ip/g") ) { xlog("L_INFO", "2 Behind the Same NAT - Disabling Mediaproxy"); # Do not use mediaproxy as the clients seem to be behind the same NAT resetflag(5); resetbflag(6); } } _______________________________________ This seems to work, but I still have got this looping, jittering feeping noise witch is getting louder and louder ... Two or three words I can talk, then it sounds, as if a group of Navajo-Indians gone attack me .... :-) Could it be the client?

Hi every body I am using ser to solve the nat problem, In my environment: invite A-->SER-->B 1. SER receive the invite message REQA from A(invite B) 2. SER judge the use B, if the B is in public network, will fix nat in the REQA message if judge the B is in private network , will not fix anything and I want to know, how to judge the B's network, when the SER receive the INVITE from A?

[Kamailio-Users] Caller and Callee behind the same NAT
by juergen＠glowka.de 29 Dec '09

29 Dec '09

Hello, I'm new here. So I say "hello" to everybody. Maybe, somebody can help me or push me in the right direction. If there are Caller and Callee behind the same NAT, so it should be better, they connect directly (e.g. 192.168.x.1 <-->192.168.x.2), instead of using the rtp-proxy (this causes a jitter noise) . I'm using Kamailio 1.5.3 with RTPPROXY 1.2.1. Has anybody a code snip or a sample kamailio.cfg for me? I would be thankful for it.

Re: [Kamailio-Users] adding inbound and outbound routes seperately

You self have to define how you want to peer. For example if you want to peer with somebody sending you inbound requests, you have to define at least: - number format - authentication (IP-based, TLS, digest) One you have defined those parameters, you can implement it, e.g. digest authentication or IP based authentication. The same for outbound route - you have to configure Kamailio so that outbound requests are sent in the proper format. And Kamailio can not register to any other SIP service. If you need such a feature, you better use Asterisk. regards klaus > > -----Original Message----- From: Klaus Darilion > [mailto:klaus.mailinglists@pernau.at] Sent: Wednesday, December 23, > 2009 8:49 AM To: Rodney Cc: users(a)lists.kamailio.org Subject: Re: > [Kamailio-Users] adding inbound and outbound routes seperately > > > On 22.12.2009 22:35, Rodney wrote: >> Ok, I have kamailio and siremis, and I need to know how to set up >> a separate in bound and outbound route. >> >> Peering with inbound and registering with outbound >> > > Kamailio is a sip proxy, thus it can not register to other SIP > proxy. > > regards klaus > >> Any ideas guys? >> >> R >> >> >> >> _______________________________________________ Kamailio (OpenSER) >> - Users mailing list Users(a)lists.kamailio.org >> http://lists.kamailio.org/cgi-bin/mailman/listinfo/users >> http://lists.openser-project.org/cgi-bin/mailman/listinfo/users

[Kamailio-Users] Newbie questions
by Antonio Goméz Soto 28 Dec '09

28 Dec '09

Hi, I have used asterisk before, but now am looking at kamailio for scaling up. I've read 'Building Telephony Systems with OpenSER', but I still have lots of questions.... so, here it goes: - I could not find a way to reboot a phone remotely, can it send SIP NOTIFY to all phones? - does it have something like the Asterisk Manager Interface, so I can connect/create an operator panel for it? Does that already exist somewhere? Something like FOP where operators can transfer calls, and check availability? - according to the docs it is not a BTBUA. What does this mean? I know that asterisk is a BTBUA, but what can a BTBUA do that a SIP proxy cannot? Is it only the moh and conferences? - lastly, is there a good tutorial on load-balancing somewhere? Thanks, Antonio.

Hi folks, I used a Draytek Vigor 2820PBX to register iptel, and I found 400 missing cookie issue. When my pbx send the reinvite to hold another side, iptel always responded pbx 400 missing cookie. But I checked invite Via field, its branch included magic cookie "z9hG4bK". I attached wireshark packets. BR Dennis

[Kamailio-Users] Transparent bridge mode
by Vikram Ragukumar 24 Dec '09

24 Dec '09

Hello All, I am trying to setup a test scenario, where i have Kamailio and rtpproxy running on one CentOS box (Server1) and i have Asterisk running on another CentOS box (Server2). Server1 has 2 NIC's eth0 and eth1 that are both assigned Public IP's. There is a transparent bridge br0 connecting eth0 and eth1 which also has its own Public IP. Finally eth0 on Server2 also has a Public IP. Server2 must be assigned a Public IP. My goal is to modify rtpproxy so that i can intercept packets traveling to Server2, process them and let them resume along their original path. I would like to know if there is another way of setting this up so that i dont use as many Public IP's ? Do any of you see a problem with this setup, things that may not work eventually, or any other concerns ? Thanks, Vikram.
