Making cost-effective

calls

Make phone calls through a network pro-

vider who offers cheap rates (call-by-call) or

have the charges displayed after the call

(ISDN only).

Using the Internet (VoIP) is the preferred

cost-effective way of making calls.

Defining dialling plans

You can also use your phone's cost control

function for calls to fixed line or mobile net-

works. In addition to your fixed line/ISDN

connection, you can open accounts with

various VoIP providers offering favourable

rates for calls to other networks. In the

phone configuration, define the best

connections (account), e.g., for specific

regional, national and mobile network

codes, to be used when calls are made

(

¢ Web configurator, Dialling Plans).

Or define the send connection to be used

when you actually dial the number (dialling

via line selection,

¢ page 51).

Linking a number with a

call-by-call number

You can predial call-by-call numbers for calls

via your ISDN or fixed line connection. Use

the call-by-call numbers to select the net-

work of a cost-effective provider for a call.

You can store the call-by-call numbers from

several network providers in the local direc-

tory (page 70).
