ASCOM Ascotel 2025 System Manual page 500

The substitution can only be switched on and off at an operator console and is
then valid for all the operator consoles in the PBX.
Personal calls are not diverted.
Calls that were signalled on the operator console before proxy was switched on
are not diverted.
If the "Subscriber" destination for the substitution is busy, caller A obtains the
busy tone. Call waiting is not automatic.
If "General call" is configured as the substitution's destination, the call is placed
in the general call's queue and caller A obtains the ring-back tone.
