What are the advantages of a Bluetooth base station?

To use a DECT/Bluetooth base station offers the advantage that you can use only one phone, e.g. the S1 or SL1 handset for incoming and outgoing calls. It is also irrelevant if the call is coming from the GSM network or not. To differentiate an incoming GSM call from a fixed line call you can also allocate a different ringer tone for GSM calls.

Furtheron you can place the GSM mobile phone at any place in a house having sufficient network reception. No call will be missed anymore and there is no need of calling the mailbox. You can make your calls via the DECT handset as well.
