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.

I already added the last ~ 20 lines of the backtrace which does show what
happend within the RTCP flow. As marcelloceschia said, he has also the bug
- therefore I think its also possible to reproduce this ticket. I think
this is an timing issue related to the establishment of the SRTP session.
Maybe the RTCP is the VERY first SRTP package which comes in and some SRTP
stuff is not already initialized.
