Protection against External Calls Being
Re-Routed to Attendants
Usually, your external calling parties can contact you from external
network(s), directly through your direct calling numbers, or DID
numbers (Direct Inward Dialling).
They may also contact you through your facility’s general number.
In this case, your incoming external calls are processed through
your facility’s attendants.
An external call is presented to you whether your extension is free
or busy. If it is busy, it will usually be automatically placed on camp-
on for your extension (unless your extension is equipped with specific
protection against such).
If you do not answer to an external call, after a typical delay of
30 seconds, the call is directed (or returned) to your facility’s
attendants for processing.
Following the specific rights assigned to your extension, you may
have access to protection against your external calls being directed
to your facility’s attendants.
This protection may apply in either of the following cases:
•
Restricted protection on no-answer condition: external calls
presented on your extension when its status is free will then ring
continuously, without a time limit, until you answer it, or the
caller ends the call.
• Restricted protection on busy condition: external calls presented
on your extension when its status is busy will remained on
camp-on, without a time limit, until you answer it, or the caller
ends the call.
• Extended protection: this combines the two previous cases.
In all cases, this protection against the re-direction of your calls to
the attendants is permanent and does not require any action on
your part.
