Using Call Features
Call Back
This service mimics the call back service offered by the PSTN. You can activate this service on a busy
number so that you are 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, you select 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, you pick up any line and enter *86. When call back service is
active, the corresponding Line key flashes green. You 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, you hear a ring back tone like a regular
outbound call.
Message Waiting Indication (MWI)
The 900 Series phone indicates message waiting in two ways:
• Turning on the red MWI light - LED (with an envelope icon right above LED) on the phone.
• Playing stutter tone instead of regular dial tone.
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 you 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
You 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.
