4012 Billed Number Screening (BellSouth Region Specific)

Third Number Billing Inhibited

This capability provides Enhanced Services Providers (ESPs) with the ability to
prevent third number calls from being billed to their switched access billing 
accounts, (e.g., DID numbers).  This capability is provided by the operating 
procedures of a BOC providing operator services capabilities.  

When a call is made to a BOC operator services system, and the caller requests 
the charges be billed to a third number, the operator makes a call to the third
number for verification that the charges will be accepted.  If no answer is 
received when the third number is called for verification of billing acceptance,
the bill to third request is rejected.

In some areas, when a call is made to a BOC operator services system, and the 
caller requests the charges be billed to a third number, the operator queries 
the Line Information Database (LIDB) to determine the billed party's preference
concerning bill to third number requests.  If the information in the LIDB 
indicates to always reject bill to third party attempts, then the bill to third
request is rejected.
