3.18 Intercom
An extension user can make an intercom call to a networked system if the networked extensions are
defined with the Network Access Code (Program 11-01, Dial Type = 8)
A user can change the signaling type for the intercom call they place to either a voice announce or
ringing call to extension in a networked system.
3.19 Keep Alive Operation
The Keep Alive operation will check that the distant end is available. A dummy message is sent that
the distant end must respond to, if no response is received the line will be taken out of service.
Keep alive operation is effective on IP AspireNet connections.
3.20 Last Number Redial
Last Number Redial allows an extension user to quickly redial the last number dialed. When used with
a networked system, the system can use the same trunk route on which the call was originally placed,
even if the trunk is a trunk in another system.
3.21 Message Waiting
This feature can be used when placing an intercom call to a networked extension and receives either
no answer or hears a busy tone.
With a networked system, when a Message Waiting has been left, there is a slight difference in the
telephone's display. With a single system, the extension's name which left the message is displayed.
With a networked system, the extension number is displayed.
3.22 Operator, Centralized
It is possible to have a centralized network operator extension that can be dialed with the operator
access code (0).
Calls to the operator will be queued and answered in order. Up to 32 calls can be queued at the
operator extension. The quantity of network calls that can queue at the operator may be limited by the
quantity of AspireNet channels available.
Operation
The network numbering plan must be set up to route the operator access code (0) to the system that
has the operator extension.
The operator extension must be set in Program 20-17-01.
