Hi Robert,
I have a question regarding a few sub-items:
Implementations using each transport for SIP messages:
UDP 100%
TCP 82%
TLS 49% (server auth only)
TLS 6% (mutual auth)
SCTP 3%
DTLS 0%
36% of the implementations supported SIP over IPv6 (up from 25% at
SIPit20)
18% supported SIP over IPSec
What does it mean when someone supports SIP over IPsec?
IPsec is independent of SIP. Is this referring to the 3GPP IPsec
security between the UA and the P-CSCF?
Support for various items:
61% rport
15% sigcomp
22% enum
21% sending multiplexing STUN and SIP
28% receiving multiplexed STUN and SIP
22% RFC4320 fixes
12% identity
70% session-timer
What type of SIP Identity support is this?
Is this support at the proxy for creating the SIP Identity header?
Is this support at the end host for creating the SIP Identity header?
Is this support at proxies that verify SIP identity?
Is this support by UAs verifying SIP identity?
Support for various things in the endpoints:
10% ICE (but there was no interoperability - see below)
0% ICE-TCP
13% STUNbis
17% TURN (again, there was no interoperability)
75% symmetric RTP
25% SRTP
0% RTP over DTLS
RTP over DTLS was an idea in an old draft for media security. The
document was dumped. Hence, the 0% is not surprising.
Ciao
Hannes
