-----------------------------------

Hi Jonathan,

sorry for delay, work to finish before christmas :-)

Well, I started to do what you asked me for, but face a new problem: in the mean time I upgraded my snom from 8.4.35 firmware to 8.7.3.15 and now no more TLS/STRP stuff :-(

I opened a issue on snom forum, you can find it here http://forum.snom.com/index.php?showtopic=11011 with all details and logs.

This story brings me crazy, don't know what to think (and to do)

Daniel

> 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.
