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

Tue May 1 16:44:00 UTC 2007

Hi peter,
    If the autentication is not enabled or call is getting from the trusted domain,then call is not authenticated,in the case,how charging is done?

As per my understanding,Registration is the currently available location of the user.If the caller is making a call with out registration then call will be charged based on the subscriber data available at the service provider. 
 CDR's which are used for the generation of the billing will contain the From header ,from where the call is intiated and billing is not done based on the contact of that user.

Authentication is useful when the  Anonymous call is made,where the user doesn't want to reveal his identity,in this scenario,the From header is anonymous,based on the p-asserted identity the call will be charged.

please comment.
