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.
Shikhar
