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.
