[asterisk-bugs] [JIRA] (ASTERISK-20499) Crash in libsrtp srtp_unprotect_rtcp when SIP channel is bridged with non-optimizing Local channel

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

Once again, I need you to use the latest (emphasis on latest) diagnostic patch (posted at 19/Nov/12 9:57 AM). That is to say srtp_diagnostic_with_sleep.diff - I am quite certain that you are still not using this patch because a log message between 'attempting srtp_create at %p' and 'result of srtp_create at %p' is missing from the results you are giving me, and there are no conditions for this log message to appear. To make things a little easier, I've deleted the old patch which didn't contain this log message.

If you don't use that particular version of the diagnostic patch, I won't be able to see why srtp_create is failing.

In the meantime, I'll go over the pcap and your configurations to see if I can't figure out why I've been having so much trouble reproducing this locally.

> 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.
