Does anybody know how to configure OpenSER 1.3 to support secure VoIP?
Another question about SIP is how difference between sips and TLS?
Hi Steven,
you find some documentation about TLS support in kamailio/ OpenSER here: http://kamailio.org/docs/tls.html.
SIPS is the secure variant of SIP, it uses TLS to encrypt its data.
IIRC the specs, sips is the indication that the user does not want to be reached unless there is a secure channel, e.g., TLS. However, not sure if this applies as well if between caller-server-callee is IP sec or other secured transport and SIP is sent over it.
Looking at uri comparison, sip:a@b.com is different than sips:a@b.com. I haven't any real sip device using sips so far. Has anybody of you seen some usage of sips indication in SIP addresses?
