Press the end call key.
Please note:
– You can specify for each handset registered to your base station which of your VoIP phone num-
bers (which VoIP account) should be used for outgoing external VoIP calls (page 99).
– If you use VoIP to make a call to the fixed network, you may also have to dial the area code for local
calls (depending on the VoIP provider). You can also enter the area code in the base station con-
figuration so you do not always need to enter it for local calls (via the phone Web configurator,
page 102). It will then be inserted automatically for local calls.
Please note:
– Dialling with the directory (page 39) or last number redial list (page 42) saves repeated keying of
phone numbers.
– You can assign a number from the directory to a key for speed dialling (page 40).
– You can edit or add to any phone number selected by means of speed dial or from the directory
and use it for the current call.
