Terminology
Called Party Number (CdPN)
In general, the term Called Party Number (CdPN) is a telephone number that has
been dialed to reach a destination. However, while routing the call, the network
can change the Called Party Number to make routing easier. In either case, the
network sends the Called Party Number to the system when a call arrives at the
system.
