Dialing - Conflicting Numbers The system can differentiate between conflicting numbers such as 1-0-0-0-0
and 1-0-0-0. In this example, if the 5th digit is not dialed within a time-out period,
the system assumes that the dialed sequence is complete and makes the call.

or hunt group so that calls from the trunk ring the station or hunt group directly.

specific answer time, and monitor the signals while being connected to silence
within the system.

using a special trunk. The system sees the DISA trunk as a station with its own
Class of Service and Class of Restriction. Calls that enter the system on DISA
trunks have access to a variety of system features. In all cases, the DISA trunk
can be assigned account codes to provide a high degree of security or
additional options.
