Hello,

you should enable core dumping - that should be via running 'ulimit -c unlimited' before you start rtpproxy.

If you get the coredump, then grab the backtrace with gdb, it should show where rtpproxy crashed. With that info, maybe we can spot a fix for it.

Hopefully rtpproxy package is with debug symbols, if not, the look for a rtpproxy-dbg package and install it if found.

Cheers,
Daniel

Hi All,

version: kamailio 4.1.0 (x86_64/linux) 350d2e
 
Doing some testing, can't seem to get rtpproxy to not segfault.  I've loaded version from deb-squeeze pkg, from source http://b2bua.org/chrome/site/rtpproxy-1.2.1.tar.gz and from git://sippy.git.sourceforge.net/gitroot/sippy/rtpproxy (which should be the latest) but all versions segfault as soon as a call sets up.
 
I've configured each versions control socket for both udp or unix, kamailio starts and sees the rtpproxy fine with no errors, but when a call hits, rtpproxy segfaults.
 
I've run rtpproxy in the forground with degug and get this response (IP's washed x.x.x):
------------------

kamailio.cfg:
loadmodule "rtpproxy.so"
modparam("rtpproxy", "rtpproxy_sock", "udp:127.0.0.1:7722")
 
inside route[]

            add_path_received();
            rtpproxy_manage("cwei");
            record_route();
 
Any guidance on further identifying the issue?
 
Thanks.
