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

Interesting... I'm going to try and lab this up with a SNOM to see what happens.  My guess is that since nothings on the 'other side' of the Local channel, something is get out of wack.  I'll post here when I have a bit more info.

> 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.
