Telephone features operation
This section describes how to use the following digital telephone features in
host-controlled modes:
Emergency service calls
Do not place an emergency service call, for instance a call for police, fire
department, or ambulance help, using a telephone connected to a Digital
Telephone IP Adapter unit.
Hold
When you press the Hold key on a host-controlled call, the holding party
receives the Hold treatment defined on the host PBX. For example, if the host
PBX is configured to play music for the holding parties, then the holding party
hears music. You can press the local calling key to place a new call.
Call Waiting
Since the Digital Telephone IP Adapter unit does not use host-controlled
indicators, there are never any indicator conflicts when a call is presented to the
station.
The Digital Telephone IP Adapter unit always checks the status of your station
before ringing it. If your station is busy with a call, the alert tone is sounded
instead.
