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 directed 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 respond 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 be manifested by: 
• 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 automated attendant is never dependant upon any action on 
your part.
