Jonathan Rose commented on ASTERISK-20499:
------------------------------------------

Ok, it sounds like Asterisk just crashed before that log message went through then. Could you please apply the patch that stopped the crashing on top of that one and tell me what you get?

> 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.
