Hi Srinath,

The Screening Indicator is used to indicate the result of the verification 
of the calling party number in the Setup message by the NETWORK side only. 
The values of this field depend on the following:

               
* Calling Party Number correct Or
  Calling Party Number partially filled     Value - user-provided, verified 
and passed

* Failure in Screeing Verification Or
  Setup doesnt contain the Calling
  Party Number                              Value - "network provided" with 
a default number


Please check out section "3.9.2.1.1.2: Actions at the originating local 
exchange if a special arrangement does not apply" in ITU-T Q.2951.

Hope this helps.
