Hi Jonathan,

I tried your solution against the usual test server with previous patch applied and get:

I tried on another server -the one for which I opened this bug, see details in my first message- asterisk is still crashing

I will send you the backtrace

> 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.
