Activate/deactivate Call beats data
On the base:
SX205isdn
Using Call beats data you can set if a call is rejected or signalled during data transmis-
sion.
Your ISDN connection offers you 2 simultaneously usable telephone lines (B channels).
Both channels are used at the same time to transmit data.
Call beats data off (factory setting):
◆
Calls during data transmission are rejected. The caller hears the busy signal.
Call beats data on:
◆
When there are calls during data transmission, the data connection is automatically
reduced to one B channel and the call is signalled.

Changing the long distance prefix
Long distance prefixes are the first few digits required when dialling another city
(national) or to another country (international). In Germany, the factory default is:
0
00
In other countries, different long distance prefixes could be used. In this case you need
to change this setting.
Otherwise, you wouldn't be able to make some calls, such as ringbacks, from the call
list.
