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

Tue May 1 22:29:52 UTC 2007

the service provider will not allow non-subscriber to use its service, so
their proxy will be configured that it can simply drop any message including
INVITE from the non-subscriber/unregistered user/suspended user, etc.
