I don't know what these OID's are to begin with. But, could these be
analog phone calls only, or digital only. You say it is reporting 1 or 2
low in each instance. Perhaps you have a couple of people calling in use
ISDN BRI lines that are actually connecting digitally. There might be a
single OID that returns all calls, while there are seperate OID's to
report analog versus digital.

Just my nickel,
