Voice Quality

Default settings for the codecs used are stored in your phone: one setting optimised 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 handset is not adequate.

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 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 receiving device to begin with. If the receiving 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.
