<Reference>
In the network shown above, PBX B functions as a tandem switch. In this example, parameters
SMDR3 and SMDR4 for RT1 of PBX B should be assigned as 1 for the following reasons.
When Station C places a call to Station A:
Since SMDR collects billing information on the outgoing trunk at PBX C, billing information
on the outgoing trunk of RT1 is not required at PBX B (SMDR3=1).
When Station A places a call to Station C:
At PBX B, SMDR collects billing information on the outgoing trunk of RT2, and therefore
billing information on the incoming trunk of RT1 is not required (SMDR4=1).
