Keep Alive - Wi-Fi Interval A “keep alive” message is a mechanism for maintaining a “pinhole” through your firewall so that
phone calls proceed smoothly. The interval specifies how often the message is sent (in seconds).
If you are experiencing problems during a Wi-Fi call (a call made over the Wi-Fi internet
connection), try setting this interval to a lower number such as 20.
Keep Alive - 3G Interval Same as above, except the interval applies to calls made over the 3G network.
