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.

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.

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.

Use this field to set the longest time that the Prestige will allow a SIP
