Hello,

is 3.2.2 from packages or tarball? If yes, can you try with latest git branch 3.2? Hints to install are here:

http://www.kamailio.org/wiki/install/3.2.x/git

Even rtpproxy should not crash in any case and a fix has to be done there, I just want to see if it is an effect of an issue fixed in rtpproxy module of kamailio.

Cheers, Daniel

Hi all,

i try to register at the rtpproxy mailinglist, but its still pending. Maybe someone here had the same issue. In my multihomed setup (with mhomed=1 in kamailio.cfg) i had segfaults from rtpproxy if i called rtpproxy_manage with params.

Notice that i must run rtpproxy as root to get core files.

Any hints? Maybe my kamailio config isnt right?
