Matt Jordan commented on ASTERISK-20499:
----------------------------------------

Thanks for providing the backtrace.  Without hitting the 'Send Back' after you've provided feedback, an issue may not show up in bug marshal's filters.

There's a few interesting things about your scenario:
# The crash is occurring on what appears to be a normal RTCP read.  Unfortunately, the crash isn't happening in Asterisk, but in a libsrtp - which means either its a bug in libsrtp, or the SRTP session wasn't initialized properly prior to the RTCP read.  Looking through the backtrace however it _appears_ as if the session is initialized; without seeing a DEBUG log leading up to the crash its a bit hard to tell.  Can you provide a DEBUG log leading up to the crash?
# You're using a non-optimizing Local channel in the bridge.  Does the crash occur when you have a SIP channel to SIP channel bridge?  Can you provide the appropriate portion of the dialplan that leads up to the crash?

> 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.
