Kamailio TLS with intermediate CA certificates
by Daniel Pocock 30 Jan '12

30 Jan '12

I found that my TLS client was not happy because my server cert is signed by an intermediate root. A quick search in Google found other people mentioning the same problem, but no solution or documentation. I've had a quick look in the Kamailio source and I notice it is using the call: SSL_CTX_use_certificate_chain_file to load the certificate specified in tls.cfg with certificate=myserver.pem In practice, this means the intermediate certificates can be appended to myserver.pem and … [View More]

Kamailio for NATted users with ICE and TURN
by Daniel Pocock 30 Jan '12

30 Jan '12

There are now a number of TURN implementations available: http://www.resiprocate.org/ReTurn_Overview http://turnserver.sourceforge.net/ and for many purposes TURN relays and ICE are much better than relying on NAT helper and rtpproxy When clients use ICE: - the client gets upset if Kamailio mangles the SDP to use rtpproxy - it is actually not necessary for the SDP to have addresses tweaked - because ICE deals with it anyway In practice, it still appears necessary for the registration server … [View More]

RPM packages - repositories update
by Daniel-Constantin Mierla 30 Jan '12

30 Jan '12

Hello, the repositories with build RPMs done via OpenSUSE Build Services (OBS) were updated. Fedora 14 is no longer offered by OBS, instead I added support for Fedora 15 and 16. Also, there are now dedicated builds for RedHat 6 and OpenSUSE 12.1. Links to repos are provided at: * http://www.kamailio.org/wiki/packages/rpms Cheers, Daniel -- Daniel-Constantin Mierla -- http://www.asipto.com http://linkedin.com/in/miconda -- http://twitter.com/miconda

save a Q850 cause reason from a reply
by Uri Shacked 30 Jan '12

Hi, the gateway i use for sending call to pstn has an option of sending a header with Q850 reason. it looks like this: " Reason: Q.850;cause=17;text="UserBusy" Reason Protocols: Q.850 Cause: 17(0x11)[User busy] " now, i need to save the reason for reports. the reason changes and i am trying to find a way to parse it and save the code only. usualy i use the "search" function to get text from headers that are the gateway's inventions :-) here i can find the text "Q850....… [View More]

Registrar ignoring socket
by Spencer Thomason 30 Jan '12

30 Jan '12

Hello, I'm working on building a HA setup with separate registrar and proxy servers. The registrar server writes to a master database that is replicated to a local database on each of the proxy servers. A load balancer then sits in front of the proxys. When routing to a registered user on the proxys I receive an error message that the socket is unknown and ignored (obviously because its on another machine). Is this just a warning message or are there any consequences to doing it … [View More]

Re: [SR-Users] Kamailio Redundancy examples/pointers required
by Javier Gallart 30 Jan '12

30 Jan '12

Hello the net.ipv4.ip_nonlocal_bind = 1 options works fine. We have a very basic redundancy level, but it fits our current needs; sometimes it's even harder to troubleshoot the redundancy failures than the actual failures. We have 2 identical servers running kamailio and listening to the same ip addresses/ports (you need to enable the sysctl option for that). A heartbeat process controls in what machine the actual ip addresses are active. The DB is in one of the servers but we update the … [View More]shared memory in both. For us having the DB down for a while is not critical because all the data is in memory. When one servers goes down the other one takes over immediately. It's a very comfortable setup also for doing upgrades in the configuration in a controlled manner.

Using forward(); with PVs
by Spencer Thomason 28 Jan '12

28 Jan '12

Hello, I'm experiencing some difficulty using forward with PVs. If the IP and port are specified directly everything works but if I use PVs for the values startup fails with a configuration error. What I'm trying to do is statelessly forward an OPTIONS request to a B2BUA that sits behind Kamailio without hard coding the address into the configuration file. Is there a better way to accomplish this? Thanks, Spencer Connected by DROID on Verizon Wireless

Selects vs PVs
by Spencer Thomason 28 Jan '12

28 Jan '12

Hello all, I'm currently reworking our routing scripts in preparation for an upgrade to 3.2.2 from 3.1.5. I'm taking this time to perform a general cleanup an optimization. In regard to selects vs PVs, is there any reason to choose one or the other select over a PV when both exist for the needed data? Thanks, Spencer

AVPs vs Variables
by Spencer Thomason 27 Jan '12

27 Jan '12

Hello all, I'm a little confused as to the difference between avps and vars and when I would use one or the other. I'm currently using sqlops to populate a few avps. Would vars be more suitable? Thanks, Spencer Connected by DROID on Verizon Wireless
