Frequently Asked Questions
How do I make a phone call?
Pick up the phone and dial. Use 7-, 10-, or 11-digit dialing for calls within the same area code as your Vonage
phone number. Use 10- or 11-digit dialing for calls outside of your area code.
Can I make calls if my Internet connection is down?
No. Your high-speed Internet connection must be active when you make Internet phone or fax calls.
Can I make calls while I’m browsing the Internet?
Yes. You can make Internet phone or fax calls while browsing the Internet. However, your web browsing may
affect the quality of your telephone call, depending on the amount of upstream data traffic passing through your
Internet connection.
Can I receive calls while my network is down?
You cannot directly receive calls while your network is down. However, Vonage can forward calls to a different
telephone number, such as a cellular phone number, if you activate a feature called Network Availability Number.
You can configure this feature through your service account at www.vonage.com.
What is the maximum number of IP addresses that the Router will support?
The Router will support up to 253 IP addresses.
Is IPSec Passthrough supported by the Router?
Yes, enable or disable IPSec Passthrough on the Security => VPN Passthrough tab.
Where is the Router installed on the network?
In a typical environment, the Router is installed between the cable/DSL modem and the local area network (LAN).
Plug the Router into the cable/DSL modem’s Ethernet port.
Does the Router support IPX or AppleTalk?
No. TCP/IP is the only protocol standard for the Internet and has become the global standard for communications.
IPX, a NetWare communications protocol used only to route messages from one node to another, and AppleTalk, a
communications protocol used on Apple and Macintosh networks, can be used for LAN to LAN connections, but
those protocols cannot connect from the Internet to the LAN.
What is Network Address Translation and what is it used for?
Network Address Translation (NAT) translates multiple IP addresses on the private LAN to one public address that
is sent out to the Internet. This adds a level of security since the address of a PC connected to the private LAN is
never transmitted on the Internet. Furthermore, NAT allows the Router to be used with low cost Internet accounts,
