You can avoid having to assign connections to certain phone numbers by using a
dialling plan for these phone numbers.
Activating a fixed line network connection as a fallback send connection
You can activate the fixed line network connection on your phone as a fallback connection. If a
call attempt fails via VoIP (IP connection or Gigaset.net), an attempt is automatically made
(without prompting) to establish a connection via the fixed line network.
¤
. . . In Alternative Connection, activate the Automatic fallback to fixed line option
A fallback is used in the following situations:
•
The IP connections are busy (you can make calls on a maximum of two IP lines at the same
time)
•
The SIP server for the VoIP connection cannot be accessed
•
The VoIP connection has not yet been configured or has not been configured correctly
(e. g. incorrect password)
•
The phone does not have a connection to the Internet, e. g. because your router is
deactivated or not connected to the Internet.
SMS messages that are to be sent via a VoIP connection are not sent via the fallback connection.
Deactivate option if you are not connected to a fixed line network (default setting).
Otherwise, you will be switched automatically to the fixed line network if no IP
connection can be established temporarily, e. g. if the phone starts faster than the
router. The phone would therefore not be functional.
Voice quality for VoIP connections
Functions to improve the voice quality on VoIP connections (IP or Gigaset.net) are available on
the web page:

Settings Telephony
The voice quality for VoIP connections is mainly determined by the voice codec used for
transferring the data and the available bandwidth of your DSL connection.
In the case of the voice codec, the voice data is digitised (coded/decoded) and compressed. A
"better" codec (better voice quality) means more data needs to be transferred, i. e. it requires a
DSL connection with a larger bandwidth. You can change the voice quality by selecting (bearing
in mind the bandwidth of your DSL connection) the voice codecs your phone is to use, and
specifying the order in which the codecs are to be suggested when a VoIP connection is
established. Default settings for the codecs used are stored in your phone; one setting optimised
for low bandwidths and one for high bandwidths. The following voice codecs are supported:
G.722
Excellent voice quality. The broadband voice codec G.722 works at the same bit rate as G.711
(64 kbit/s per speech connection) but with a higher sampling rate. You can use this to play
back higher frequencies. The speech tone is therefore clearer and better than with the other
codecs (High Definition Sound Performance).
