The following table describes the labels in this screen.
10.8 Speed Dial
Speed dial provides shortcuts for dialing frequently used (VoIP) phone numbers.
10.8.1 Peer-to-Peer Calls
You can call another VoIP device directly without going through a SIP server. You must set
up a speed dial entry in the phone book in order to do this. Select Non-Proxy (Use IP or
URL) in the Type column and enter the callee’s IP address or domain name. The Prestige
sends SIP INVITE requests to the peer VoIP device when you use the speed dial entry.
You do not need to configure a SIP account on the Prestige 2602HW in order to make a peer-
to-peer VoIP call. You must still configure a SIP account on the Prestige 2602HW-L in order
to make a peer-to-peer VoIP call.

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) to reduce the
bandwidth that a call uses. The Prestige will generate and send comfort noise
when you are not talking.
Dialing Interval When you are dialing a telephone number the Prestige waits this long after you
stop pressing the buttons before initiating the call. Select how many seconds
you want the Prestige to wait after the last input on the telephone’s keypad
before dialing (making) a call.
