16.2 CO Transit - In
Description
When a DID call is received by a networked system, the system will attempt normal DID call
routing. The ICLID table is examined, followed by the MSN table, then the defined DID
number conversion is completed. The system does a look-up in the Flexible DID Table to
identify the destination. If the number is an extension in a networked system, the system
routes the call to the destination over the appropriate network connection with CLI provided to
the called station.
Consideration
CO Transit-In calls are not subject to recall or time restrictions at the originating system.
If no path is available over the network, the caller will receive busy tone.
The system, which originally received the call, will generate two SMDR records for the call,
the original incoming call and the transit-call to the destination station.
