Summary:                    Asterisk Crash on RTCP package in SRTP mode
Description: 
"snom360-SIP 8.4.18 42570" connected to Asterisk with TLS. snom makes an
outbound call to another phone (without srtp). Other telephone does ring -
then Asterisk does crash. 

libsrtp version 1.4.4. was used - without a change.

This problem also exists in 1.8.1-rc1.

I'm also using Snom 300 phones with the 8.4.18 firmware.  As
marcelloceschia stated, disabling RTCP Support on the phone itself did seem
to solve the immediate problem.

I'd like to mirror bernhards concerns that this is a very serious bug and
hope that Digium elevates this bug in their queue accordingly.
