[Kamailio-Users] RTP timeout and nathelper
by mayamatakeshi 11 May '09

11 May '09

Hello, RTPProxy 1.2.0 can be instructed to notify and external app when RTP timeout occurs. It seems this notification must be enabled on a per session basis. So, does module nathelper have the means to request this notification? regards, takeshi

[Kamailio-Users] two UACs behind same NAT
by dubravko caric 11 May '09

11 May '09

Hi all, I have a problem when using two UACs behind same NAT on Linksys WRT54GL router. Registrations, Invites, ... are handled correctly, but after 30sec in the call UACs hangs up the call (RTP goes directly between clients). This happens because UAC#1 (which answerd the call with OK) didn't recive ACK from UAC#2. This isn't happening when I have this same clinets behind NAT on PIX525 and everything is working fine. Everithing is also fine when UAC#1 calls someone on PSTN (RTP is handled by RTPProxy) or someone behind other NAT. Strange thing is that UAC#1 sends Ringing response and OK message with this information in Contact header: Contact: <sip:bob@public_ip_address:31479;rinstance=e0f8548cf68b5b6e> but proxy forwards this Ringing response and OK message to UAC#2 with this information in Contact header: Contact: <sip:bob@public_ip_address:0;rinstance=b18efeaa8a0e3f0f> so port is "0" and with ngrep on proxy I saw that this port is replaced with port "5060" and ACK is sent to the UAC#1 with this parameters public_ip_address:5060 which isn't correct because UAC#1 is using 31478-31488 port range and expects traffic on these ports. Some of debug messages that i see on proxy are: 1. sl_filter_ACK: to late to be a local ACK!, 2. e2e proxy ACK found building branch for end2end ACK totag for e2e ACK found: 1 I'm using Kamailio 1.5.0 with standard kamailio.cfg and newest XLite (with STUN and ICE options turn on). I would be greatfull if someone can give me any guidelines what to look next in order to solve this issue. Best regards Dubravko

Hi, Creating openser database on the localhost works fine using "kamdbctl create". However, I need to create openser database on an external mysql server. I tried the following command but it's not working: kamdbctl create openser@<external_mysql_server_ip> What's the correct command?

[Kamailio-Users] H.323 / SIP signalling gateway for OpenSER
by Bilbo 07 May '09

07 May '09

Hi, Has anyone tried connecting the 'Cisco Unified Border Element' to OpenSER as a H.323 /SIP signalling gateway to allow H.323 video calls to be placed over OpenSER? Can you see any problems trying to connect these two systems together?

[Kamailio-Users] Arbitrary contact added in 302 generated responses
by Francisco Javier Lizaran Vilches 04 May '09

04 May '09

Hi all: Have running this script on Openser 1.2.3-notls version managing forwards this way: route[3] { ... t_on_failure("1"); if avp_db_load("$ru", "*") { if (is_avp_set("$avp(s:fwdbusy)/s")) { setflag(23); }; ... failure_route[1] { ... if ((isflagset(23)) && (t_check_status("486"))) { if (avp_pushto("$ru", "$avp(s:fwdbusy)")) { t_reply("302","Moved Temporarily"); return; }; }; ... User A calls user B and B has fwdbusy parameter set in user preferences; if B is busy, proxy sends 302 message back to A with contact set to $avp(s:fwdbusy) value. This setup usually works fine. However, sometimes the proxy shows a strange behaviour. It starts to append an arbitrary contact to the contact header in every forwarding it does. The contact appended has nothing to do with A or B or the uri set in the avp. The same uri is appended in all call forwardings performed in the system. If the proxy is restarted, the problem disappears. Example: SIP/2.0 302 Moved Temporarily Via: SIP/2.0/UDP 10.100.2.254:5060;branch=z9hG4bK51461DD5 From: <sip:30132@10.100.2.254 <sip%3A30132(a)10.100.2.254>>;tag=92DAB388-EE7 To: <sip:20050@domain.com <sip%3A20050(a)domain.com> >;tag=880a5593aeb097bc75600b31d6e17107-78ac Call-ID: C0C84A1C-33CE11DE-BEBEEAA9-C0D323DF(a)192.168.2.40 CSeq: 101 INVITE Contact: sip:30050@domain.com <sip%3A30050(a)domain.com>, <sip:030410@10.172.0.254:5060;transport=udp>;q=0 Server: OpenSER (1.2.3-notls (i386/linux)) Content-Length: 0 <sip:030410@10.172.0.254:5060;transport=udp>;q=0 is added in all forwardings done the system. Unfortunately I have no debug info cause it happens in production environment. I couldn't reproduce the problem in test environment. Have you got any idea on what could make it happen? Thanks a lot: Fran Lizaran
