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.

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

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.

Note: 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.

Note: 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.

Display Name

Type a name to interoperate with other SIP devices. It is recommended to leave 

the default setting for this field.

SIP Service Domain

Enter the SIP service domain name in this field (the domain name that comes 

after the @ symbol in a full SIP URI). You can use up to 127 ASCII Extended 

set characters.

of your Prestige’s connection to the SIP server.

wireless LAN, Internet and SIP settings changes do not take affect until you use
