DESCRIPTION
Keep the default value, unless your VoIP service provider tells you to change it.
Enter the number of seconds the SIP server should provide the message waiting
service each time the V500 subscribes to the service. Before this time passes, the
V500 automatically subscribes again.
Configure this option to have the V500 automatically dial the Hotline Number
after the line is off the hook for the duration specified in the Delay Period option.
This is especially useful for dialing emergency numbers.
Select this to enable the Hot Line feature.
Enter the duration the phone can remain off the hook before automatically dialing
the hotline number. You can set the delay from 1 to 15 seconds.
Enter the number to be dialed once the V500 has surpassed the delay period.
Select this if you want the V500 to use the call forwarding rules you set up in the
VoIP > Phone Book > Call Forward screen.
Select this to turn the RingBack function on. When someone calls you, and the
line is busy, the caller is given the option to set an automatic RingBack. When you
finish your call, the V500 automatically calls the person who called you, and then
rings to alert you once the caller picks up.
Check this box if you want people to hear a customized recording when you put
them on hold. This function depends on your service provider.
Enter your presence server IP address.
Enter your presence server port number.
Enter the number of seconds to wait before expiring a user's presence setting on
the network.
