How best to experiment with SIP over Websocket?

by Juan Castro

As per the instructions here... http://www.kamailio.org/w/2012/07/websockets ...I downloaded the latest source from Git... http://www.kamailio.org/w/download/ ...but I don't see any mention of Websocket anywhere in the source. I suspect I didn't actually download the development tree, but the 3.3 branch. Last time I messed with any VoIP code was in 2008 (OpenSER and Asterisk) and now I'm starting all over again. I apologize for the dumb newbie question, but how do I test the Websocket code? -- Juan Carlos Castro y Castro Instant Solutions - Telefonia Gerando Resultado http://www.instant.com.br Principais capitais: 4063-6100 Demais regiões: (11)4063-6100

Kamailio Presence with XCAP not working accordingly

by SamyGo

Hi, I've followed the tutorial on kab.asipto.com for presence using built-in xcap server. http://kb.asipto.com/kamailio:presence:k31-made-simple I'm using Kamailio version 3.3.1 and did minor changes in modparams and rtpproxy function calls and the kamailio accepted the configurations file posted on the page and started. But the problem is that I don't get the presence status of the contacts still. Please suggest what to look for and how to troubleshoot this. I get this error on Jitsi - image attached. ERROR: "http://ip.of.server/xcap-root/xcap-caps/global/index resource can not be read" Regards, Sammy

Best tool for crafting sip messages

by Anton Kvashenkin

Hello, guys. What is the best tool for crafting sip messages for testing purpose? For example, simple REGISTER or INVITE message. I'm new to kamailio (not sip) so it would be great for me to use debbuger module for step-by-step digging into cfg.

Kamailio LCR Module test scenario

by Fatima Chahrour~Vanrise Support

Dears, Am trying to apply Kamailio LCR feature lab test, after am finally able to run Kamailio with no errors, am not able to reach my target clarified in this following scenario: Call 961312345 - route the call to 192.x.x.15 in first place and if failed route the call to 192.x.x.10. I applied needed configuration in lcr tables (attached image) and the routing script is: route{ if (!mf_process_maxfwd_header("10")) { sl_send_reply("483","Too Many Hops"); exit; }; if (msg:len >= 2048 ) { sl_send_reply("513", "Message too big"); exit; }; if (!method=="REGISTER") record_route(); if (loose_route()) { append_hf("P-hint: rr-enforced\r\n"); route(1); }; if (!uri==myself) { append_hf("P-hint: outbound\r\n"); route(1); }; if (is_method("INVITE")) { if (!load_gws(1)) { sl_send_reply("503", "Unable to load gateways"); exit; } } if (uri==myself) { if (method=="REGISTER") { save("location"); exit; }; lookup("aliases"); if (!uri==myself) { append_hf("P-hint: outbound alias\r\n"); route(1); }; # native SIP destinations are handled using ourUSRLOC DB if (!lookup("location")) { sl_send_reply("404", "Not Found"); exit; }; append_hf("P-hint: usrloc applied\r\n"); }; route(1); } route[1] { if (!t_relay()) { sl_reply_error(); }; exit; } BUT when attempting a call am getting the message 'Call failed: Not found .' Any help to achieve the successful call using above scenario is highly appreciated. Thanks in advance. F.Chahrour
