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.
