[SIPForum-discussion] Issue in Initiation/Termination of callwith De-Registered User

[Brecl, Peter]

The user would still need to get authenticated when it sends out the
INVITE. If the authentication for the INVITE passes (it uses the same
credentials as the authentication pwd for registrations), you would
accept the request for the outbound call and bill based on the billing
record created by that call.
