Overriding an automatic offline event from the host PBX

If the host PBX attempts to process an offline event while you are on a host-
controlled call, you are alerted by both an audible alert and a display message
indicating that you are about to go offline in 30, 20, or 10 seconds. If you ignore
this warning, your call disconnects.
To prevent your call from being disconnected, enter the online SPRE code. You
can do this without putting your call on hold first. The online SPRE code cancels
the offline event, leaving your telephone online until the next offline event
occurs.
On-Demand and Permanent Allocation to Remote Gateway 911x
series units
Nortel recommends that you do not enable the On-Demand feature when
configuring a PSTN port to the Remote Gateway 911x series unit. Doing so can
cause the following to occur:
The Remote Gateway 911x series unit can activate voice-mail prematurely
(after one or two rings).
The incoming host-controlled caller hears ringback.
Note: Incoming locally controlled callers may hear a busy signal or modem
tones. Do not advertise this number for local calls.
For more information about on-demand and permanent allocation, refer to
"Deployment" on page 48.
