Voicemail 
The message-waiting icon on the handset is activated with the 
message indication of the deskset. The voicemail feature on the 
deskset must be assigned to the feature key as shown in the key-map 
diagrams. Do not assign any other feature to this key, since the 
associated LED is directly mapped to the message-waiting icon on the 
handset. This LED assignment must be used in order to support the 
message-waiting icon. Using this key for any other feature or for line 
access could cause unacceptable system performance. 
Speakerphone 
If a handset such s the PTB 4xx has no speaker, speakerphone 
function and functions that require the use of the volume keys will 
not be made available on the handset. 
Intercom 
The Intercom button on the 8012S Impact deskset is assigned to the 
LINE + 9 sequence on the handset. 
Ring types 
Handset ring types (soft, normal, vibrate, etc.) are programmed by the 
handset user and are not accessible or changeable by the system 
switch. Whenever possible the audible ringer on the handset will 
follow the cadence provided by the system switch. Call progress tones 
provided by the host system will be passed through to the handset.
