The combination of this object and the corresponding instance
of csfFilterCallingPartyMask is one selection criteria
for this record. To match this selection criteria, a failed
connection setup must have a Calling Party Address which has
the same length as, and is equal in value to
csfFilterCallingParty for all bits that are 1 in the

match this filtering criteria for any calling address in the
