Attendant-Based Services

Notes:

Certain extensions (such as yours) may possibly be equipped

with permanent protection against call intrusion.

Depending on the configuration for your facility defined by

your system administrator, these services may be used

from specific extensions that are duly authorised, without

any warning tones being emitted. This refers to the Silent

call monitoring service.
