13 Using handset connected to a BSIP2 base
The functions of your OpenScape Cordless IP V2 are available on the registered handsets. The functions of the
telephone system are added to the handset menu. Handset-specific functions, e.g., local directory or organiser,
are not described here. Information about this will be found in the relevant handset user guide. The availability of
functions or their designations may differ on individual handsets.
13.1 Making calls
You can make calls using any handset registered to your OpenScape Cordless IP V2.
Prerequisite:
You are located in the cell of at least one of the base stations registered to the telephone system.
The cells of the base stations together form the DECT wireless network of the telephone system. You can initiate
or answer calls on a handset across the whole wireless network and change cells during a call (handover).
Prerequisite for handover:
The base stations involved must be assigned to the same cluster and must be syn-
chronised |( p. 31).
Each handset is assigned a send and receive connection ( p. 52).
If your OpenScape Cordless IP V2 is connected to a PBX that permits the formation of groups, VoIP connections
can also be assigned to groups. In this case, you will also receive calls on your handset that have been sent to
your group number.
The OpenScape Cordless IP V2 uses a VoIP PBX Communication System or the services of a VoIP provider for
Internet telephony. The availability of some phone functions depends on whether they are supported by the PBX/
provider and whether they have been enabled. If necessary, you can obtain a description of the services from the
operator of your PBX.

13.1.2 Dialling from the redial list
The redial list contains the numbers last dialled with the handset.
Depending on the specifications of your PBX, you may need to dial an access code for calls outside
the area covered by your VoIP PBX (
If you make a call to the fixed line network, you may also have to dial the area code for local calls
(depending on the PABX/provider). This is not necessary if the area code is entered in the configuration
on the DECT Manager ( p. 63).
