Routing Table
CPID Manipulation
CPID Manipulation defines rules for how Calling Number, Calling Name, Called Number, Called
Name, Redirect Number, and Redirect Name appear in the destination call. Typically, the calling
and called numbers from the incoming call are simply passed through to the outgoing call.
However, there are cases where it is desirable to alter either or both of these numbers. A “CPID
Manipulation” rule is applied to all calls routed via the Routing Table. Each of the rules applies a
formula using the incoming CPID information as inputs to determine the outgoing call's CPID.
Table 14 shows the syntax used for CPID Manipulation.
