LABEL DESCRIPTION
Phone Port Settings Use this field to select the phone port that you want to configure.
Speaking Volume Use this field to set the loudness that the Prestige uses for the speech signal
that it sends to the peer device. -1 is the quietest and 1 is the loudest.
Listening Volume Use this field to set the loudness that the Prestige uses for the speech signal
that it receives from the peer device and sends to your phone. -1 is the quietest
and 1 is the loudest.
Outgoing Call use SIP 1 and SIP 2 correspond to the Prestige’s SIP accounts. Select whether you
want the phone(s) attached to this phone port to use SIP account 1, 2 or both
when you make a call. If you select both SIP accounts, the Prestige will first try
to use SIP account 2 and then SIP account 1 when you make a call.
You cannot call the SIP number of the SIP account that you are using to make
a call. The Prestige generates a busy tone and does not attempt to establish a
call if the SIP number you dial matches the outgoing SIP number of the phone
port you are using.
For example, if you set
Phone 1 to use SIP account 1 and set Phone 2 to use
SIP account 2, then you can use Phone 1 to call to SIP account 2's SIP
number or Phone 2 to call to SIP account 1's SIP number.
G.168 Active Select this check box to cancel the echo caused by the sound of your voice
reverberating in the telephone receiver while you talk.
VAD Support Select this check box to use Voice Activity Detection (VAD).
VAD reduces the bandwidth that a call uses by not transmitting when you are
not speaking.
