Volume for VoIP Calls
Depending on the VoIP provider, it is possible that the received voice/earpiece vol-
ume is too low or too high, so that adjusting the volume via the handset is not ade-
quate.
Specify whether the received volume range is too high or too low. The following
options are available:
Low
Voice/earpiece volume is too high. Activate 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. Activate this option to increase 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 for outgoing calls into the
Selected codecs list.
To do this, in the Available codecs list select the voice codec that you want
to apply (you can mark several entries using the Shift key or the Ctrl key). Select
<Add.
¤
Move the voice codecs that you do not want the phone to use into the Available
codecs list.
Select the voice codecs in the Selected 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 receiving device to begin with. If the receiving
device does not accept this voice codec (e.g. because it is not supported), 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 established. An appropriate message will be dis-
played on the handset.
If the phone always starts by trying to establish a broadband connection, put the
G.722 codec at the top of the Selected codecs list.
