[SR-Users] rtpproxy 1.2.1 segfaults with kamailio 3.2.2 in bridging mode

[Daniel-Constantin Mierla]

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
