Supporting TLS and DTLS in RTP Proxy
by Kamal Palei 16 Oct '12

16 Oct '12

Hi All I am planning to enhance RTP proxy to support TLS and DTLS. We have some requirements where we need to send RTP packets either over TLS or over DTLS. I really do not know where to start :-) Few things that I have thought over is 1. I will take opnssl code base and integrate with rtpproxy code. 2. Will refer kamailio proxy code how tls connection framework is there and try to copy the code from kamailio code base to rtp proxy code base, OR is there a better alternative here. If somebody has a better idea, kindly share. Thanks a lot. -kamal

Guidance on using Kamailio as Presence Server and Scalability issues for millions of subsribers
by Thomas Hoffman 16 Oct '12

16 Oct '12

We're trying to determine how best to design/architect a solution where we use Kamailio as a Presence/XCAP server and be scalable to support millions of subscribers. I see the Dispatcher module, but it appears that requires having dedicated instances of the server running just in Dispatcher mode - then you can load balance across the actual instances of the presence servers. It's not clear if a server can be configured to work as a dispatcher and a presence server at the same time. Does anyone have any high-level guidance how to approach this problem?

Hi, My kamailio installation usually works right, but sometimes, it crashes and it shows the following error: "ERROR: ctl [ctl.c:379]: ERROR: ctl: could not delete unix socket /tmp/kamailio_ctl: Operation not permitted (1) " Do you know why it happens randomly or what's the cause ? Many thanks. Br, Marina ________________________________ Este mensaje se dirige exclusivamente a su destinatario.

preparing kamailio 3.3.2
by Daniel-Constantin Mierla 16 Oct '12

16 Oct '12

Hello, I am considering packaging Kamailio v3.3.2 at the beginning of next week (Monday or Tuesday). If any of the devs have backports to be done, do them before the end of this week. Also, if someone spotted some fixes in the master that were not backported, write to the lists so we can care of them. Thanks, Daniel -- Daniel-Constantin Mierla - http://www.asipto.com http://twitter.com/#!/miconda - http://www.linkedin.com/in/miconda Kamailio Advanced Training, Berlin, Nov 5-8, 2012 - http://asipto.com/u/kat Kamailio Advanced Training, Miami, USA, Nov 12-14, 2012 - http://asipto.com/u/katu

You can't, exactly.
