Calling Party Number — MWI Identification

Parameter group

ISDN signaling

Access level


Possible values

A text string containing up to 40 characters. Valid characters are 0 through 9, A, B, C, D, *, and #.




If this calling party number is set, it will appear in an outgoing ISDN call setup message. The calling party number is used to identify which Blueworx Voice Response client is requesting to set or clear a Message Waiting indicator.

In this case, the MWI is being controlled over the D-channel and the feature is currently available only for the ISDN QSIG signal process.
