This is 10.10.0 from another VM running under Wheezy on a third server (the one generally used to debug this issue). One patch 377261 is applied, there is no more crash unlike the first test on the physical IBM machine in the same conditions. Instead, I have

> A call from snom320 in SRTP mode to echo test or to another phone *NOT* using SRTP is OK. Now we installed PhonerLite softphone with TLS/SRTP stuf and test with echo test: everything is OK too.
> Now PhonerLite calls the snom: asterisk coredump after 3~5 seconds and we are NOT able to make anymore SRTP calls after this, they all crash asterisk. We had this issue with 10.7.0 and 10.8.0
> We have logfiel from strace as well as coredump.
