All completions of call are automatically deleted after a predefined period. This time is set by the service provider for
external call-backs and by the PABX system for internal call-backs.

If the ISDN telephone is disconnected from the ISDN network, (for example by unplugging the ISDN connector of
the phone or by switching off or resetting the pabx), all requested call completions will be lost.
Parking a call (not with IP-S400)
The parking function allows you to interrupt a call for up to three minutes. You can then unplug the plug-in
connector for your ISDN system telephone from the ISDN jack and plug it in in a different room. You can continue
with the previous call after »unparking« it. Or you can »unpark« the call at a different phone and continue your call
there.
Parkingis only possible when only one connection is currentlyactive with your telephone. After you unpark the call,
the number for the parked subscriber will no longer be shown.
A »parking code« (0. . . . 99) is used to ensure that you are returned to the proper call when two calls are parked. The
default parking code is 55.
Information:
If you park two calls on anISDN bus this bus is then disabled for further calls. Unparkingis possible only on the bus
on which the call was also parked. Parking is only possible when only one connection is currently active with your
telephone.
