Making cost-effective calls

Using the Internet (VoIP) is the preferred cost-effective way of making calls.
You can also use your phone's cost control function for calls to fixed line or mobile phone

networks. Open accounts with various VoIP providers who offer favourable rates for calls

to other networks. In the phone configuration, define the best VoIP connections (account),

e.g. for specific regional, national and mobile network prefixes, to be used when calls are

made (

Dialling Plans

, page 149). Or define the VoIP connection to be used when dialling the

number (dialling with line suffix, page 32).

If you are using your fixed line network to make a call, choose a network provider that

offers particularly favourable rates (call-by-call). You can manage call-by-call numbers in

the call-by-call list

to the numbers.
