LABEL	DESCRIPTION

Registrar Server Address	Enter the SIP register server’s IP address or domain name in this field.
	You can use up to 95 ASCII characters.
	If you were not given a register server address, then enter the
	address from the SIP Server Address field again here.
Registrar Server Port	Enter the SIP register server’s listening port for SIP in this field.
	If you were not given a register server port, then enter the port
	from the SIP Server Port field again here.
Register Expiry Time (sec.)	This field sets how long an entry remains registered with the SIP
	register server. After this time period expires, the SIP register server
	deletes the Prestige’s entry from the database of registered SIP
	numbers. The register server can use a different time period. The
	Prestige sends another registration request after half of this configured
	time period has expired.
OPTIONS Interval Timer	The OPTIONS Interval Timer periodically sends a signal to the SIP
	Proxy Server to maintain the connection.
	Type a time in minutes to send a KeepAlive signal to the SIP Proxy
	Server. The default is 0, which disables this feature.
Session Expiry Time (sec.)	Use this field to set the longest time that the Prestige will allow a SIP
	session to remain idle (without traffic) before dropping it.

	leave the default setting for this field.

	ASCII Extended set characters.

	SIP-Server.
Registrar Password	Type in the password to associate with the username above.

	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.

13.3 Voice Coding

A codec (coder/decoder) codes analog voice signals into digital signals and decodes the digital signals back into voice signals. The Prestige supports the following codecs.

13.3.1 G.711

G.711 is a Pulse Code Modulation (PCM) waveform codec. G.711 provides very good sound quality but requires 64kbps of bandwidth.

Pulse Code Modulation (PCM) measures analog signal amplitudes at regular time intervals and converts them into bits.
