PPTP DHCP
Select this option if your ISP uses PPTP (Point to Point Tunneling Protocol) and did
not assign a static IP address to your account. Enter the Username and Password
for your Internet account. Also enter the Server IP address for the ISP server. Also
configure your connection with the Keep Alive or Connect On Demand option, as
described below.
• Keep Alive: Choose this option to use Keep Alive messages to keep the
connection permanently open, regardless of the level of Internet activity by
your users.
• Connect On Demand: Choose this option to open a connection only when
a user attempts to connect to the Internet. In the Max Idle Time field, enter
the number of minutes of inactivity that will cause the connection to be
terminated. This option is recommended if your billing is based on the time
that you are connected.
Optionally, you can enter a Domain Name, if provided by your ISP.
One disadvantage of using a dynamic IP address is that if your IP address changes,
your Unified Communications System and all connected devices will reboot.
Telephone service will be interrupted.
PPTP Static
Select this option if your ISP uses PPTP (Point to Point Tunneling Protocol) and
gave you a static IP address. Enter the Username and Password for your Internet
account. Enter your static IP Address, the Subnet Mask, the IP address of the
Default Gateway, and the IP address for the Primary DNS server, as provided by
your ISP.
Optionally, you can enter a Secondary DNS server. Also configure your
connection with the Keep Alive or Connect On Demand option, as described
below.
• Keep Alive: Choose this option to use Keep Alive messages to keep the
connection permanently open, regardless of the level of Internet activity by
your users.
• Connect On Demand: Choose this option to open a connection only when
a user attempts to connect to the Internet. In the Max Idle Time field, enter
the number of minutes of inactivity that will cause the connection to be
terminated. This option is recommended if your billing is based on the time
that you are connected.
Optionally, you can enter a Domain Name, if provided by your ISP.
