LABEL	DESCRIPTION

Default Voice Codec	A voice codec (coder/decoder) converts voice data to electrical signals for
	transmission over a network.
	Use this field to select the type of voice coder/decoder (codec) that you want the
	Prestige to use. Choosing a voice codec depends on a tradeoff between
	transmission speed, sound quality and desired bandwidth usage. G.711 provides
	higher voice quality than G.729 but requires 64kbps of bandwidth while G.729
	only requires 8kbps. The Prestige can only connect to other phones that use the
	same codec as the Prestige.
	If you want to use G.711, G.711u is used mainly in North America and G.711a is
	used in most of the rest of the world.
Speaking Volume(-	Select the default gain for the Prestige’s microphone, where –14 is the minimum
14~14)	(least sensitive) and 14 is the maximum (most responsive).
	The callee may hear an echo if you set the microphone’s volume to the
	maximum.
Listening Volume(-	Select the default speaker volume on the Prestige, where –14 is the minimum
14~14)	(quietest) and 14 is the maximum (loudest).
RTP Port	Real time Transport Protocol is used to handle voice data transfer. Use this field
	to configure the Prestige’s listening port for RTP traffic. Leave this field set to the
	defaults if you were not given a RTP port to use.
Jitter Buffer	A larger receiving buffer allows the Prestige to rearrange data packets that arrive
	in the wrong order.
	Packets are dropped if they arrive out of order and the receiving buffer is full.
	Increasing the buffer size introduces latency. Too large of a buffer could
	introduce a significant delay with a slow connection. Too small of a buffer may
	result in packets being lost.
Voice Frames per	Use smaller packet sizes to reduce the number of speech frames sent per
Packet	packet. If a small packet does not reach its destination is it less significant than if
	the packet contained many speech frames.
DTMF Relay	Dual Tone Multi-Frequency signals are generated when you press a key on the
	Keypad and communicate information (such as telephone numbers) to the VoIP
	gateway.
	Select disable to send the DTMF digits uncompressed from the remaining
	protocols to use a compression method to match that of your VoIP service
	provider’s.
	Select Inband(RFC 2833) to send the DTMF tones in RTP packets.
	Select Outband to send the DTMF tones in SIP messages.

DTMF Payload (0-	This field allows you to set the DTMF payload type. It is recommended to leave
127)	the default setting for this field.
APPLY	Click APPLY to save your changes without restarting the Prestige. Your wireless
	LAN, Internet and SIP settings changes do not take affect until you use
	RESTART (in the navigation panel).
CANCEL	Click CANCEL to begin configuring this screen afresh.
