properly and has an in-service facility connected to it.

Station Message Detail Recording
(SMDR) Reports Do Not Include
Calls across the Private Network
SMDR reports may report calls using more than one call record on more than
one system. Depending upon how SMDR is programmed and how calls are
routed, you may need to consult several SMDR records to trace a call that is
routed over private network tandem trunks. To log private network calls, SMDR
should be programmed to report both incoming and outgoing calls.
The diagram above shows how a single call, routed across a private network, is
both an incoming and an outgoing call in the same system. For private network
calls, outgoing call records report the incoming tandem trunk number in the
STN. field (see System B above). Dialed digits shown on the report do not
reflect any digit manipulation (addition or absorption) performed by the local
system.
Calls across the private network are not recorded, even at a tandem switch, if
the call is not answered unless the outgoing facility is a loop-start or
ground-start trunk. Then calls are logged, even unanswered calls.
If the system date and time are not synchronized across the private network, it
may be hard to recognize the records for a single call, even when the systems
