Yes... Authentication challenge can happen for any request except CANCEL and ACK
Authentication mechanism is the Digest Authentication. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Shikhar Sarkar Sent: Thursday, October 13, 2005 4:25 AM To: [email protected] Subject: [Sip-implementors] Authenticating an incoming SIP call Guys, Is there a way to authenticate a SIP user for incoming call scenario such as: IAM Invite SS7----------->Softswitch------------->WiFi SIP device The WiFi SIP device of course has already registered with Softswitch. But is that enough to assume that there is no clone/eavesdropper? I am wondering why I always see 401/407 challenges always opposite to the direction of Invite. Is there a way to include Authentication challenge in the Invite itself? Please throw some light.
