Hi All, I'm seeing random errors in my Kamailio 3.0.2 log: ERROR: tm [tm.c:1300]: ERROR: w_t_relay_to: t_relay_to failed ERROR: tm [t_fwd.c:1379]: ERROR: t_forward_nonack: no branches for forwarding After going blind staring at wireshark, I can consistently reproduce this error by initiating a call, then after about a second ro two, quickly hanging up. So here is my setup: SIP Phone><Asterisk><Kamailio><SIP Service Provider I see all transaction messages flowing properly through all nodes and I don't get any hung channels, all call legs release properly. I'm guessing I need a special [route] in Kamailio to handle 487 request so they look normal and not issue an error? Kamailio is forwarding the 487 messages ok, so why do I get a t_relay error? What info would be helpful to diagnose the errors? Any insight would be appreciated. Thanks. JR -- JR Richardson Engineering for the Masses

installing dispatcher module

by Rizwan Qureshi

Hi List, This is my first email to this list and I am a kamailio newbie. I have worked on asterisk a lot but this is the first time im going to use kamailio. I have successfully installed kamailio on my centos system. I can see all the modules located in the /usr/local/lib/kamailio/modules_k/ AND /usr/local/lib/kamailio/modules/ directories. But the problem is when i try to load the dispatcher module from kamailio.cfg it gives me the following error. loading modules under /usr/local/lib/kamailio/modules_k/:/usr/local/lib/kamailio/modules/ ERROR: bad config file (1 errors) Has anyone any clue why this is happening? I cant find any details about thsi error otherwise i would have posted it. Cheers Best Regards Rizwan Qureshi

How can I remove all RPID headers from SIP message

by Mino Haluz

Hi, I tried to add RPID headers at the beggining of SIP options on the client side, and I was able to change the caller number simply this way. How can I avoid this ? I'm searching for some function in Kamailio which would delete all RPID headers so that Kamailio could add only one (and correct) RPID header (I'm using append_rpid_hf) Thanks.

LCR Question

by Trevor Francis

I have managed to work my way through the LCR module documentation and added the loadmodule and module parameters. However, I dont know where to add the routing logic that will allow me to add LCR rules and gateways in Siremis and to have Kamailio recognize them.

DoS on Kamailio

by Bernhard Suttner

Hi, is there a Kamailio module to prevent DoS Attacks like SIP Register Scanners? I know, that there is a way to implement that with Fail2Ban and xlog but it would be nice to have a "pure" Kamailio solution for that? Any idea is appreciated. Best regards, Bernhard Suttner
