Hi,
the digest authentication defined in the RFC 3261 and in the RFC 2617 is designed for that purpose. There is also "RFC3310 Hypertext Transfer Protocol (HTTP) Digest Authentication Using Authentication and Key Agreement (AKA)" for 3GPP networks.

Subject: [Sip-implementors] Does SIP offer a way to authenticate the
caller?
Hi all,
As far as I can see, there is no caller authentication in SIP ( i.e.
one can initiate calls through SIP Proxies without being registered).
However, to use SIP with IMS in UMTS, there must be a way to authenticate
the caller ( i.e. to verify that the caller is really the one in the FROM
header of the INVITE message). I've read some 3GPP specifications (24.228,
24.229) but I haven't found how they do that. Please help me with this.
Looking forward to hearing from you,
Minh Phan
