Troubleshooting
If the solutions listed here do not solve your problem, for more troubleshooting help contact Vonage as described
in
“Contact Us”
on page 66.
Problem
Possible Solutions
Power light is off
Check that the AC power adapter is properly plugged into the electrical outlet and the
VT2542.
Check that the electrical outlet is working.
Cannot send or receive
data or phone calls
or
No dial tone
If you subscribed to just one phone line from Vonage, be sure your phone is
connected to the
Phone 1
port on the VT2542.
Check all other cabling between the modem, the VT2542, and the computer. Be sure
you used the cables provided with the VT2542. All Ethernet cables must be
straight-through cables.
Check the lights on the
Front Panel
(see page 2).
Check the lights on the modem front panel. For information, see your cable or DSL
modem user guide.
If you have only one phone line, be sure your phone is plugged into the green phone
port 1 on the VT2542.
Can you access Web pages? If not, check to see whether your ISP (cable or DSL) is
having connection issues in your area.
Be sure the telephone connected to the VT2542 is disconnected from the wall jacks
that traditional phone companies use. If not, the VT2542 cannot connect with the
Vonage server and you will not get a dial tone.
Compare your device connections to those shown in
“Connecting the VT2542”
on
page 6 or
“Connect the power adapter to the Power port on the rear panel of the voice
gateway, and plug the other end into an electrical outlet.”
on page 7.
The order in which you turn the devices on is very important. Try the procedure for
“Resetting All of Your Equipment”
on page 65.
A computer cannot
send or receive data
Check that the Ethernet cable is properly connected to the VT2542 and the computer.
If you have a cable modem
only
, check that your TV is working and the picture is
clear. If you cannot receive TV channels, your cable data service will not function.
Contact your cable provider.
If you have a DSL modem
only
, check that your DSL service is working. Contact your
DSL provider.
My high-speed Internet
connection uses a USB
port, not an Ethernet
port
You need to switch your high-speed Internet connection from USB to Ethernet to use
Vonage Internet Phone Service. If your computer does not have an Ethernet
adapter
,
you can purchase an Ethernet adapter or a USB to Ethernet Converter to connect
your computer to the VT2542, and ultimately the Internet.

Frequently Asked Questions
If you do not understand a term or abbreviation, check the
Glossary
.
Q
What does the Motorola VT2542 Voice Gateway do?
A
The VT2542 Voice Gateway is a stand-alone media terminal adapter (S-MTA) containing a home router:
•
As an S-MTA, it converts analog voice signals to and from a standard telephone to digital data that can
be transmitted through a broadband connection across the Internet. It provides an alternate means to
make voice calls.
•
Its built-in router provides full network connectivity, a firewall, and VPN passthrough.
Q
Will the VT2542 Voice Gateway work with a cable modem or DSL modem?
A
Yes. The VT2542 Voice Gateway supports
DHCP
, which is specified for
DOCSIS
®
cable modems, and
PPPoE
, which is used by most DSL providers.
Q
Can I operate a virtual private network (VPN) application behind the VT2542?
A
Yes. The VT2542 Voice Gateway supports
IPSec
and
PPTP
, the most common VPN protocols.
Q
Can I play online games through my VT2542?
A
By default, the voice gateway blocks all unsolicited messages to the computer or local network as a standard
security measure. However, for online games that require some unsolicited messages to be transmitted
through the voice gateway, you can specify ports and IP addresses on which to allow unsolicited messages.
The VT2542 enables you to set up virtual servers or a
DMZ
.
Q
How do I configure the VT2542?
A
Most people can send and receive calls immediately after completing
Installation
! You can configure your
home or office network through a GUI using a connected computer configured to obtain its IP address using
DHCP. Or, you can configure the computer statically to 192.168.15.xxx (xxx is from 2 to 254), subnet mask
255.255.255.0, and default gateway 192.168.15.1.
Q
What is included with the built-in router?
A
The VT2542 supports a firewall, RIP, port triggers, advanced ALGs such as RSVP, POP3, SNMP, and
streaming media. No separate routers are needed.
Q
Is any Quality of Service (QoS) implemented on the VT2542 Voice Gateway?
A
Although VoIP service is typically best-effort, the VT2542 provides upstream voice prioritization to ensure that
upstream voice data has priority over other Web data. This ensures good voice quality even during heavy
upstream data transfers, such as e-mail synchronization or file sharing.
