Using Call Features

Call Back

This service mimics the call back service offered by the PSTN. The user can activate this
service on a busy number such that he is called back as soon as the busy number becomes
available. The 900 Series phone implements this feature by repeatedly dialing the busy number
periodically until the called party rings or answers, or until the service order is canceled by the
user or expires. For that reason, it is referred to as the repeat dialing service.
To activate this service, the user selects a line key and enters *66 (call back activation code).
The 900 Series phone then uses this call appearance to call the last called number. The retry
period and expiration time are configurable. To cancel the service, the user picks up any line
and enters *86. When call back service is active, the corresponding Line key flashes green. The
user can still use this line to make or answer calls. The call back service is temporarily paused
until the call appearance is idle again.
When the call back number rings or answers, the call appearance rings like a normal incoming
call (the ring to be used is the default ring for the corresponding extension for that Line key).
If the call back party answers the call before the local user does, the 900 Series phone sends a
holding tone to the call back party. If the local user picks up the call back Line key first, the
user hears a ring back tone like a regular outbound call.

Message Waiting Indication (MWI)

The 900 Series phone indicates message waiting in two ways:
•
•
The MWI light only applies to new message indication received on Extension 1. It is not turned
on or off due to new message indication received on the other extensions [2 to 4]. On the other
hand, the 900 Series phone can be configured to play a stutter tone on the individual call
appearance according to the message waiting state of the corresponding Extension X.

Accessing Voicemail

The 900 Series phone has a voicemail retrieval key for quick access to voicemail. If a voicemail
access number or URL is not specified, pressing the key brings up a screen where the user can
enter the appropriate information. This information can also be entered from the web page or
downloaded via provisioning. The 900 Series phone attempts to call the voicemail number or
URL if there is an idle call appearance available.

Muting Calls

The user can mute the audio input into the phone when an audio device is switched on, by
pressing the MUTE key. To un-mute, press the MUTE key again. If no audio device is on,
pressing the Mute key has no effect. When switching from the speaker phone to the handset,
the phone is automatically un-muted.
