Selective load_credentials in auth_db
by Alex Balashov 11 Dec '13

11 Dec '13

I have some extra columns to load from the 'subscriber' table': modparam("auth_db", "load_credentials", "$avp(s:fruit_id)=fruit_id"); Is there any way to get auth_db to only load this column for one realm and not another? I use multiple realms (tables) and one of them doesn't have this column. -- Alex Balashov - Principal Evariste Systems LLC 235 E Ponce de Leon Ave Suite 106 Decatur, GA 30030 United States Tel: +1-678-954-0670 Web: http://www.evaristesys.com/, http://www.alexbalashov.com/

force_send_socket
by Keith 11 Dec '13

11 Dec '13

Hi, I am using force_send_socket as I have two interfaces. It works fine but at the moment I am hard coding the IP address. I want to use a variable instead, I have tried the following: force_send_socket($sel(cfg_get.kamailio.bindip); But kamailio doesn't start and complains about the format. Any ideas? Thanks, Keith

Kamailio + mediaproxy-ng for webrtc to sip calls
by Muhammad Shahzad 11 Dec '13

11 Dec '13

Hi, According to documentation, using kamailio's rtpproxy-ng module with mediaproxy-ng service, it is possible to make webrtc to sip calls and vice versa, However i am stuck since morning to make JSSIP (in chrome) to phonerlite (in Windows 8) calls. There is not working example or sample code anywhere either. So i was wondering if anyone has actually tries that successfully and would care to share some samples for us. So, far i tried "+SP" flags for phonerlite to JSSIP calls and "-sp" for JSSIP to phonerlite calls in "rtpproxy_manage" method. Apparently both calls connects but then drop after a few seconds of ACK. Which indicate the problem is likely to be on mediaproxy-ng end rather then kamailio..

kamailio/script call route(...) in switch(...) expression
by Seudin Kasumovic 11 Dec '13

11 Dec '13

Hi, Let route[FOO]{...} returns -1, 0, or 1 value. Next example never print message in case -1: switch (route(FOO)) { case -1: xlog("L_INFO", "FOO = -1\n"); break; case 0: xlog("L_INFO", "FOO = zero\n"); break; case 1: xlog("L_INFO", "FOO = +1\n"); break; } Result from route(FOO) less then to zero converted to 0, so never get label -1, but next example works properly (when use $rc): route(FOO); switch ($rc) { case -1: xlog("L_INFO", "FOO = -1\n"); break; case 0: xlog("L_INFO", "FOO = zero\n"); break; case 1: xlog("L_INFO", "FOO = +1\n"); break; } Is this bug, or regular behavior ? Regards, Seudin

Re: [SR-Users] Differnce Bettween F_MALLOC and DSF_MALLOC defines

Hello, only F_MALLOC and Q_MALLOC were tested for production. The others are attempts to have alternatives, you should test it well and see if you get any benefits there.

Configuring Kamailio as an authenticating SIP Proxy?
by Mark D. Montgomery II 10 Dec '13

10 Dec '13

Here's the issue: I have a FreePBX server running at a location that 1. Is not directly accessible from all the outside locations I would be at 2. I don't want the SIP ports directly open to it from the whole world anyway for security reasons. I have a VPS that I am currently using as a pure SIP redirector via firewall rules, and the main location allows connection from the VPS only. The issue I've run into (which is the same issue as having the main server open to the world), is that I still get a fair number of exploit hits to the server. What I'd like to do is use Kamailio as an authenticating proxy so I could use fail2ban on the VPS to ban the offenders when they try to exploit the server. Basically I want Kamailio to handle passing authentication back and forth from the client to the actual server and then handle proxying the full connection when the auth is correct. Is this doable? If so, how would I go about setting it up? It looks like Kamailio should be able to do just about anything, but I don't know where to start. Thanks. Mark II -- Mark D.

how to string concatination
by Grant Bagdasarian 10 Dec '13

10 Dec '13

Hello, How do I concatenate a string to an avp variable? $avp(s:caller) = $fU; if($(avp(s:caller){s.substr,0,2}) != "00") { $avp(s:caller) = "00$avp(s:caller)"; } This piece of code does not work as the value of $avp(s:caller) is "00$avp(s:caller)"

Hi Daniel-Constantin Mierla, Could you please help me on this.. What is the difference between these two defines F_MALLOC and SF_MALLOC. Currently we are compiling with F_MALLOC option. When we can enable SF_MALLOC define, Will it improve the performance?

Kamailio generating 408 Request Timeout?
by Grant Bagdasarian 09 Dec '13

09 Dec '13

Hello, I'm seeing Kamailio generating 408 Request Timeout responses which are sent back to the originator. And it also generates a CANCEL to the terminating party. I assume this is normal behavior. Which timer controls this timeout? Is the 408 generated only when no final reply is received? Regards, Grant
