Voice Quality
Default settings for the codecs used are
stored in your phone: one setting opti-
mised for narrow bandwidths and one
setting optimised for wide bandwidths.
¤
Activate one of the options Optimized
for low bandwidth / Optimized for high
bandwidth if you wish to accept a
default setting for all VoIP connec-
tions. The settings are shown in the
Settings for Connections area and can-
not be changed.
¤
Activate the Own Codec preference
option if you wish to select and set
connection-specific voice codecs
yourself (see "Area: Settings for Con-
nections").
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
by 6 dB.
Voice codecs
Precondition: The Own Codec preference
option is activated for the Voice Quality
in the Settings for Bandwidth area.
Select the voice codecs your phone is to
use, and specify the order in which the
codecs are to be suggested when a VoIP
connection is established via this VoIP
phone number.
¤
Apply the voice codecs that your
phone is to suggest with outgoing
calls into the Selected codecs list.
To do this, in the Available codecs list
click on the voice codec that you
want to apply (you can mark several
entries using the Shift key or the Ctrl
key). Click on the <Add button.
¤
Move the voice codecs that you do
not want the phone to use into the
Available codecs list.
Also, select the voice codecs in the
Available codecs list (see above) and
click on the Remove> button.
¤
Sort the voice codecs in the Selected
codecs list into the order in which
they should be suggested to the
receiving device when a connection
is established. To do this, use the Up
and Down buttons.
When establishing a VoIP connection,
the phone suggests the 1st voice codec
in the Selected codecs list to the receiv-
ing device to begin with. If the receiv-
ing device does not accept this voice
codec (e.g. because it is not sup-
ported), the 2nd voice codec on the list
is suggested and so on.
If the receiving device does not accept
any of the voice codecs in the Selected
codecs list, the connection is not estab-
lished. An appropriate message will be
displayed on the handset.
