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.

DESCRIPTION
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.
Note: If you were not given a register server port, then enter the
port from the SIP Server Port field again here.
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.
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 session to
remain idle (without traffic) before dropping it.
Type a name to interoperate with other SIP devices. It is recommended to leave
the default setting for this field.
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.
Type in the username exactly as supplied by your VoIP service provider.
Type in the password associated with the username above exactly as supplied
by your VoIP service provider.
This displays either Registered or Not Registered depending on the success
of your Prestige's connection to the SIP server.
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).
Click CANCEL to begin configuring this screen afresh.
