This section describes how to use the following digital telephone features in
host- or locally controlled modes:
Note: The Conference and Call Forward features are supported for
host-controlled calls only.
Emergency service calls
The Remote Gateway 9150 unit allows an emergency number (for example, 911
in North America) to be programmed by your system administrator.
If the PSTN is used to route calls, and someone dials this emergency service
number on any station that is connected to the Remote Gateway 9150 unit, the
call is processed by your local telephone service provider.
You can initiate the emergency service call on either the host call appearance
(primary DN) key or local call appearance key. You do not have to dial a trunk
access code first.

ATTENTION!
If only the IP network is being used to route calls, you must
use a telephone that is directly connected to the PSTN to
place an emergency service call. If you place the call on a
station that is connected to the Remote Gateway 9150 unit,
the call is routed through the host PBX, which can in a
different city.
