Description: The combination of this object and the corresponding instance of reroutingFilterCallingPartyLength is one selection criteria for this record. To match this selection criteria, a call setup must have a Calling Party Address which has an initial part (of length reroutingFilterCalledPartyLength bits) equal in value to reroutingFilterCallingParty. When the default value for the object is retained then the call will match this filtering criteria for any calling address in the call, or if the calling party number is not present in the call. The value must be padded with zeros from reroutingFilterCallingPartyLength to the full length of the address (8 octets for E.164 numbers and 20 octets for AESAs).
