Functions used for receiving calls

Collect call barring

When this feature is activated, the system automatically
rejects all incoming collect calls over a digital line. Calls
received over an analog line are rejected only at the mo-
ment they are answered.
Types of collect call barring:
• Collect call barring by extension
(see Programming an extension - collect call barring
by extension, in the programming manual)
• Collect call barring for a UCD subscriber group
The system bypasses collect call barring for mem-
bers and non-members of the UCD group. This
means that collect call barring is only acknowl-
edged.
(see Programming an extension - collect call barring
for a UCD subscriber group, in the programming
manual)
• Collect call barring for Fax/DID
Call barring will not work for calls transferred to a
Fax/DID.
(see Fax/DID - collect call barring for Fax/DID, in the
programming manual)

Overflow extension

An overflow extension only receives calls when the ex-
tension that was called is not available, that is, when it
is busy, there is no answer, or the number called does
not exist.
Examples:
• The extension called is activated for room monitor-
ing (Babyphone)
• The extension that was programmed as the first at-
tendant is currently assigned as internal entrance
telephone
• No first attendant has been configured for the exten-
sion
Another way to access an Overflow extension is by di-
aling its internal number
[1] The overflow extension cannot be configured or used for Fax (see
Programming an extension - overflow extension, in the program-
ming manual).
