by Brian Echesa 05 Feb '15

Hi, Kindly assist. I have successfully installed Kamailio and Asterisk. Asterisk is acting as an PSTN in my case. The trunk between Kamailio and Asterisk is up. Issue is that i can not route calls to the PSTN. I am using the default configuration version: kamailio 4.2.2 (i386/linux) OS: Debian wheezy -- Kind regards, Brian Linux registered user: . #565878 www.brianechesa.com

[OT] ssl certificates updated for kamailio.org
by Daniel-Constantin Mierla 03 Feb '15

03 Feb '15

Hello, short note to say that I updated the ssl certificates for kamailio.org web site. They are issued by cacert.org, which is probably not trusted by most of the browsers, but they are well known in the open source environment. If you get a warning about certificate change and the issuer is cacert.org, then you should be safe to login over https (e.g., to edit the wiki pages).

Ro_CCR function
by Shane Harrison 03 Feb '15

03 Feb '15

Hi all, In a previous post I was alerted to the (perhaps obvious) fact that that ims_charging module is design to run within an IMS environment: http://lists.sip-router.org/pipermail/sr-users/2015-January/086675.html I have subsequently attempted to modify the module to work with the standard usrloc Kamailio module. I decided to branch from the 4.2.2 release rather than the master since I was unsure of the state of the ims_charging module in the master. It now compiles fine and installs. … [View More]I also have the cdp module talking watchdog_requests to a freeDiameter server so at that level things seem OK. However inserting the Ro_CCR() call into the kamailio cfg file shows up some problems, primarily: Feb 2 01:05:52 hh-rcs-sipproxy3 /usr/sbin/kamailio[6473]: WARNING: usrloc [dlist.c:624]: register_udomain(): Registering a new domain called 'voip.we-rcs.flowcloud.systems' with usrloc Feb 2 01:05:52 hh-rcs-sipproxy3 /usr/sbin/kamailio[6473]: ERROR: <core> [db.c:443]: db_check_table_version(): invalid version 0 for table voip.we-rcs.flowcloud.systems found, expected 6 (check table structure and table "version") Exploring this error leads me to a few questions: 1) The 4.2.2 Ro_CCR() has the diameter domain as a parameter. The addition of this function to my kamailio.cfg file causes ro_fixup() -> domain_fixup() -> ul.register_domain which as per the log above, attempts to look for a table with the same name as the domain. Is it expected that such a table exists, for standard Kamailio I thought all usrloc records simply go into the Location table , regardless of the domain. 2) What is the purpose of the ro_fixup() 3) I notice that the 4.3 module documentation for ims_charging module has 6 parameters for the function call while the example code given in the same section as only 5 (missing domain). The code from the master branch for the function is different again - not sure if 4.3 is still in quite a bit of flux or not for the ims_charging module? 4) Should I be using 4.3 ims_charging module as a starting point or is 4.2.2 good enough i.e are there major changes? At this stage I am going to create a table for the domain but would like some clarity on how the usrloc and domains relate to table names.

Grouped dispatching
by Grant Bagdasarian 02 Feb '15

02 Feb '15

Hello, Would the below scenario be possible using the dispatcher module or any other routing module? Destination 1: 192.168.1.1 Destination 2: 192.168.1.2 Destination 3: 172.168.1.1 These three destinations belong to the same distribution group(set), but Kamailio has to do the following: Perform round-robin using destination 1 and 2, but if both are down fail-over to destination 3. I hope I'm being clear enough. Regards, Grant

Video Key-Frame Request using RTCP FIR or SIP INFO message
by Muhammad Shahzad 02 Feb '15

02 Feb '15

Hi, This may be a bit out of focus topic for this forum but i am posting it here anyway with hope that some guru would shed some light on it and point me to right direction. The problem is that i want to establish video call between a webrtc and a sip client using kamailio (for signalling) and RTPEngine (for media relay). Both signalling and the audio stream seems to work perfectly fine The remote video on webrtc client side (i.e. video stream from sip client) takes about 20-30 seconds to … [View More]
