2.35 Calling Name Conversion Facility (CNCF)

The CNCF (Calling Name Conversion Facility) simplifies the way calling name information is delivered in telecommunications. It converts ISUP IAM messages (used in traditional telephony) between two formats:

• Using a proprietary PIP (Party Information Parameter)
• Using the standard GN (Generic Name Parameter)

A new stop action called “CNCF” has been added to the Gateway Screening feature. When the screening process stops, specific stop actions can be assigned to the screen set. These stop actions define what the vSTP does with an MSU that passes gateway screening.

When the CNCF stop action is used:

• The PIP parameter in the incoming ISUP IAM message is converted to the GN parameter.
• The GN parameter is converted to the PIP parameter.
• The message is sent to the node identified by the DPC (Destination Point Code) in the routing label.
