Area: Settings for Connections
In this area you can make specific settings
for each of your VoIP phone numbers.
You can make the following settings for
each VoIP phone number configured on
your phone:
Volume for VoIP Calls
Depending on the VoIP provider, it is
possible that the received voice/ear-
piece volume is too low or too high, so
that adjusting the volume via the hand-
set is not adequate.
Specify whether the received volume
range is too high or too low. The follow-
ing options are available:
Low
Voice/earpiece volume is too high. Acti-
vate this option to reduce the volume
by 6 dB.
Normal
The voice/earpiece volume does not
need to be raised/lowered.
High
Voice/earpiece volume is too low. Acti-
vate this option to reduce the volume
