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.
Please note
u
You should only deactivate codecs (put them in the Available codecs list)
if there is a particular reason. The more codecs that are deactivated, the greater
the risk that calls will not be able to be established due to unsuccessful codec
negotiations. In particular you can only establish broadband connections if you
permit the G.722 codec.
u
With incoming calls, all supported voice codecs are always permitted.
