data traffic at the same time over the DSL line, the voice quality may not be opti-
mum. To ensure optimum voice quality, you can use this option to define the
bandwidth, which is to be used as a maximum for your VoIP connection. The
upstream bandwidth is set automatically by default.
To define a fixed upstream bandwidth choose
Fixed
from the
Maximum
upstream bandwidth
option menu and enter the desired value.
The default value is 1000 kbit/s and should suffice under normal circumstances.
You can change these values if necessary, but you have to find out first how high
your upstream transmission rate is. Most providers supply tools for administering
your DSL connection, which should tell you this information. Otherwise, you will
find plenty of Web sites on the Internet that provide such tools.
Enter a value for
Maximum upstream bandwidth
, which is 90 percent of your
available bandwidth.

output (speak), simply enter a different value.
The value range is -24 to +24.
The higher the value, the higher the volume.
The real value range which can be used depends on your device. If you enter a
wrong value, a message with the valid value range will be displayed.
