More Features of Your Extension

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.
