The NPI and TON in CDR feature applies only for incoming ISDN trunk
calls. NPI and TON information depends on the incoming trunk protocol.
The NPI and TON fields are left blank for internal calls, outgoing trunks,
incoming non-ISDN trunks, or if the CLID prompt is set to NO.
When the FCDR prompt is set to OLD, the NPI and TON fields do not exist,
regardless of how the CLID prompt is defined.
NPI and TON information is available with the following incoming
interfaces: EuroISDN, QSIG (ISO and ETSI), MCDN, non-UIPE and
non-MCDN, and NI2.
NPI and TON information is included in all types of CDR records that contain
CLID information.
