Voice quality
¤
Select the voice quality that matches the bandwidth of your DSL connection.
–
Optimised for high bandwidth
– Optimised for low bandwidth
– Select
Own Codec preference
if you want to determine the codecs yourself.
Both parties involved in a phone connection (caller/sender and recipient) must use the
same voice codec. The voice codec is negotiated between the sender and the recipient
when establishing a connection. You can influence the voice quality by selecting (bearing
in mind the bandwidth of your Internet connection) the voice codecs your phone is to
use, and specifying the order in which the codecs are to be suggested when a VoIP con-
nection is established.
¤
Select the required codecs and define the sequence in which they should be used.
The following voice codecs are supported by your phone:
Silence suppression
Silence suppression means that no data packets are sent during a pause in speaking. This
means a lower data volume but call participants may interpret it as an interruption to the
connection.
¤
Select
No
if you do not want silence suppression. The default setting is
Yes
.

kbit/s per voice connection) but at a higher sampling rate (16 kHz) and there-
fore provides excellent sound quality.

Your phone supports G.726 with a transmission rate of
32 kbit/s per voice connection.
