Hi All,
I have a doubt about the usage of SIPS URI as mentioned in
the RFC 3329.
RFC 3329 (Section 2.4 Page 9) says:
If "tls" is chosen, the client uses the procedures of
Section 8.1.2 of [1] to determine
the URI to be used as an input to the DNS procedures
of [5]. However, if the URI is a
SIP URI, it MUST treat the scheme as if it were sips,
not sip. If the URI scheme is
not sip, the request MUST be sent using TLS.
When the TLS mechanism has been chosen after negotiating the
Security Agreement and the
URI is a SIP URI, what of the below ways should be followed ?
* The SIP URI has to be changed to SIPS URI i.e.,
Request-URI, To and From has to be
changed to the SIPS URI
(or)
* The SIP URI has to be send in the TLS connection
without changing it to the SIPS URI
Also, explain what the sentence "SIP URI MUST treat the scheme as if it were
sips, not sip",
mentioned in the RFC 3329, tends to say.
Thanks,
Gangadharan.
