Summary:                    SRTP does not work if used togather with TLS
Description: 
I am testing snom phones with asterisk 1.8. I configured SRTP and managed
to make it work. But as soon as I configured TLS as well, SRTP stopped
working. Once I removed TLS, SRTP works again.

---------------------------------------------------------------------- 
I am afraid the source of my problem was Wireshark: during my tests, I used
Wireshark to view the PCAP traces. Since the SIP packets were TLS, my
Wireshark did not correctly decode them and misinterpreted the SRTP packets
as being RTP. But actually the packets were always SRTP. I managed to get
my Wireshark to decode everything correctly and my tests are now
successfull.
I can confirm now that asterisk 1.8 works with TLS+SRTP on snom phones
