Kamailio HA with Virtual IP and multiple Asterisk servers for dispatching
by Rumen Mihailov 29 Nov '12

29 Nov '12

Hi all, Please bear with me as this is my first post to a mailing list ever so something might be quite wrong. My question is: How do we make Kamailio HA ? For the moment I’ve setup MySQL cluster with MySQL proxies that provide 1 Virtual IP that I use to connect Kamailio to (for usrloc and dispatcher) I have a couple of asterisk servers that Kamailio servers are supposed to send calls to. I have two kamailio servers that share the same IP address with keepalived. Both Kamailio servers are … [View More]

You need some sort of media gateway or server. I don't know of any that currently support this.

Hello, So, I built the memcached module against the latest Git production branch of memcached and libmemcache-1.4.0.rc2 (the latest available), on Debian i386.

Eavesdropping SRTP sessions
by Mino Haluz 28 Nov '12

28 Nov '12

Hi, maybe it is not that kamailio related question, but I dont know any other place with such good voip professionals ;) I have kamailio and mediaproxy. Clients are BudgetTone 200 (Grandstream) and CSipSimple. I am forcing clients to use SRTP but it does not support adding any certificate on both sides. SRTP call is working fine. The question is, in this case, is man-in-the-middle attack possible? Maybe I should study SRTP more, but basically, if there are no certificates, there is no method … [View More]

Managing expiration values with memcached
by Alex Balashov 28 Nov '12

28 Nov '12

According to the memcached module docs, setting $mctex(key) can be used to modify the expiration value of a key. Should this be done after or before setting the key itself with $mct(...)? I have tried it before and the assignment didn't work, so clearly the key must first exist in memcache: $mctex(bgn=>$avp(s:bgn)) = $sel(cfg_get.bgn_expiry); $mct(bgn=>$avp(s:bgn)) = $dbr(ra=>[0,0]); Nov 28 05:23:41 diminuendo-1 /usr/local/sbin/kamailio[32089]: ERROR: <core> [lvalue.… [View More]
