WebRTC + Kamailio as SIP-proxy + rtpproxy(?) as media-proxy
by Rahul MathuR 27 Nov '14

27 Nov '14

Hello, I'm new to WebRTC although I've been using kamailio as sip proxy server for few months now. What I really do not know and trying to understand is - a) Can kamailio be used as sip-proxy while using WebRTC based UA calling to plain UAC/WebRTC based UAC ? b) What to use for media proxying (this really baffles me..) rtpproxy or rtpengine (?) or mediaproxy or rtpproxy-ng ? Is there any relation between them anywhere? c) I am not behind NAT and do not want secure web-sockets, so any sample config I can refer to ? d) Most likely, I'd be dealing with WebRTC <----->kamailio <-------> Freeswitch, but any pointers for WebRTC UAC to WebRTC based UAC or normal UAC would really be helpful. Kindly accept my thanks in advance for this !! -- Warm Regds. MathuRahul

Some Questions about Kamailio UDP Transport and Concurrency
by Tony Peng 27 Nov '14

27 Nov '14

Dear Kamailio Developers： Hi. I have some questions about kamailio, and want to gain some suggestions from you. 1、The 4 UDP child processes are using system resources(CPU、memory), but they are using only one CPU core(I use 8 core CPU). Why? 2、The ablity of handling the Concurrency is alike, no matter how many UDP child processes I use. Why? And what's the effection of the other UDP child processes?

Hi, I'm trying to achieve this configuration phone --> NAT --> kamailio loadbalancer --> kamailio sip/proxy --> kamailio sip/proxy With the attached configuration I can make calls without any problems but when the callee hangs up the call does not end only the caller can hang up.

Configuring TLS and WSS with Kamailio
by Kamrul Khan 25 Nov '14

25 Nov '14

Hi, Im trying to connect my WebRTC clietn to kamailio via WSS. I successfully connected it via WS but having trouble connecting it via WSS. My first issue is I get error messages while i try to compile TLS module(console log in the end of the document). But, still it creates tls.so file. So i copied the tls.so to my kamailio modules directory and then updated my kamailio configuration as below: #!define WITH_TLS . .listen=tcp:127.0.0.1:5061 listen=tcp:192.168.146.133:5061 . . #!ifdef WITH_TLS enable_tls=yes #!endif . . #!ifdef WITH_TLS # ----- tls params ----- modparam("tls", "config", "/usr/local/kamailio-devel/etc/kamailio/tls.cfg") #!endif Now, according to this mailing list,http://lists.sip-router.org/pipermail/sr-users/2013-March/077182.html : “when tls module is installed, a self signed pair of certificate-private key is generated in /usr/local/etc/kamailio” In my case, I dont even have the /usr/local/etc/kamailio directory. So, I followed http://www.kamailio.org/dokuwiki/doku.php/tls:create-certificates to create my certificate and key. And updated my tsl.cfg, this is how my tsl.cfg looks like: [server:192.168.146.133:5061] method = TLSv1 verify_certificate = no require_certificate = no private_key = /etc/certs/sip.192.168.146.133/key.pem certificate = /etc/certs/sip.192.168.146.133/cert.pem ca_list = /etc/certs/demoCA/cert.pem [client:192.168.146.133:5061] verify_certificate = yes require_certificate = yes Then I restarted my kamailio server. And i get the following errors in my kamailio log: Im not sure what wrong im doing.

Problems installation Kamailio Ubuntu 12.04
by kai.ohnacker＠cbc.de 25 Nov '14

Hello everybody, I tried to install Kamailio 4.1 with help of this instruction -> http://www.kamailio.org/wiki/install/4.1.x/git. But, if I type the command (Root:/usr/local/src/kamailio-4.1#) git clone --depth 1 git://git.sip-router.org/kamailio kamailio I got this message back fatal: unable to connect to git.sip-router.org: git.sip-router.org[0: 78.46.84.71]: errno=Connection timed out If I open the website git.sip-router.org with my webbrowser, I got a connection. Does somebody know what the problem might be? Best regards, Kai O.

General debugging and presence question
by Jesse S. Anderson 25 Nov '14

25 Nov '14

Hi All, Sorry for the general questions here, I'll try to be concise. I'm kind of a n00b, so bear with me. Problem: Kamailio will not respond or accept SUBSCRIBE. It kicks back a 404 every time. SUBSCRIBE is ok. Question #1: I actually copied a config from the vendor we are using and it's supposed to work so is there something simple I'm missing? Question #2: Logging. I've read that there should be a kamailio.log file somewhere that I can tail -f, but there's no such file on the machine. I've done a *kamailio debug -dd *but it's really tough to go through. Doesn't seem like you can grep using that either. If anyone out there has any advice for me, I would certainly appreciate it. Thanks!

Kamailio does not delete expired contacts
by Bui Minh Yen 24 Nov '14

24 Nov '14

Hi everyone, I am using Kamailio-4.1.5. I met a problem that Kamailio does not delete expired contact. I enable log file for module usrloc and see that, about 1 first hour, timer callback of usrloc module working fine (delete all expired contacts). But after that, it is not called --> Expired contacts in shared memory and database are not deleted. I configured usrloc module like that: # ----- usrloc params ----- modparam("usrloc", "db_url", DBURL) modparam("usrloc", "db_mode", 2) modparam("usrloc", "use_domain", MULTIDOMAIN) modparam("usrloc", "db_ops_ruid", 1) Could you help me to fix this problem! Thanks so much!
