Making Cost-Effective Calls - Siemens Gigaset C470 IP Manual

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 137). Or define the VoIP connection to be used when dialling the
number (dialling with line suffix, page 31).
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
Linking call-by-call numbers with a number
You can prefix a network provider's number ("chaining") to numbers dialled via a fixed line
network
