GETTING STARTED…
LAUNCHING VIDEOLINK
Getting started with VideoLink is easy. The first time you launch VideoLink, the
registration window displays asking you to register your e-mail address. In fact, you
cannot start VideoLink until you have registered and authorized your e-mail address. See
Registering VideoLink for details.
You can launch VideoLink using either of two methods:
• From the Control Strip
• From your hard drive

If not already logged on to the Internet, do so now, then follow these steps:
• Click the VideoLink module on your control strip to display the VideoLink menu.
• Select the menu item you want (i.e Make A Call, Help…, etc.).
Launching VideoLink from your hard drive
If not already logged on to the Internet, do so now, then follow these steps:
• Open your hard drive.
• Double-click the VideoLink application folder.
• Double-click the VideoLink application. The VideoLink menu bar displays.

REGISTERING VIDEOLINK
VideoLink is an Internet communications service allowing access to registered users
only. You must register with VideoLink before using it. A registered user must have an
authorized, legitimate e-mail address. (To protect its users, VideoLink does not allow
access to unregistered users.)
Registration with VideoLink is FREE and provides many benefits such as:
• Linking Internet users together via legitimate e-mail addresses.
• Making everyone accessible via the Internet.
• Delivering the Internet’s cost efficiency and convenience to the communications
forefront.
• Allows us to inform you of new updates to the VideoLink product.
After registration, you can use VideoLink to communicate every time you log into the
Internet. If you do not want to log in automatically, you can change this by reconfiguring
your Preferences.
REGISTRATION INSTRUCTIONS
• Make sure that your email account information is properly completed in the Internet
Control Panel. If it is not, please do so now.
• If not already connected to the Internet, do so now.
• Launch VideoLink. You will see a dialog that tells you that your registration is in
progress and that you should check you email for an authentication response.
• Check your email. You should see an email with the subject “Simply reply to
complete your VideoLink.com registration!“ Select this email and click your e-mail
application's Reply then Send buttons. This is your way of authorizing VideoLink to
sign you up for the free service. DO NOT edit this email in any way. Editing the
email may cause the user authentication to fail.
When the GateKeeper server receives your reply, it verifies your e-mail address and
registers you as a valid VideoLink user. You will then see a dialog that tells you that you
are now a registered user.
• Approved: If you entered a verifiable e-mail address, your Control Strip module
notifies you that your registration is approved and you may begin using
VideoLink.
VideoLink Users Guide Smith Micro Software Inc.
8
• Unapproved: If you entered a non-verifiable e-mail address, your Control Strip
module notifies you that your registration is rejected and you may not begin using
VideoLink.
There are three states that VideoLink can be in: registered and ready to place/receive
calls, not registered, and authenticating. These states are reflected by the icon of the
VideoLink control strip module. Read the info below to clarify how the state of the
software is shown in the module.
If the VideoLink module has a red "X" on top instead of a red arc, either you have not
completed the registration process, or your current VideoLink availability status is
offline/disconnected. You are not able to listen for incoming calls.
If the VideoLink module has a red arc on top you are now able to listen for incoming
calls.
If the VideoLink module appears gray, VideoLink is currently in the registration process
and is communicating with the GateKeeper server to authenticate you.
Are you using multiple e-mail accounts? If you have more than one email account
accessing the Internet from your workstation, VideoLink requires re-registration
each time a different user logs into the Internet.
VideoLink Users Guide Smith Micro Software Inc.

ABOUT THE GATEKEEPER
VideoLink uses an Internet standard name server called a Gatekeeper in order to locate
other VideoLink users. The Gatekeeper uses your email address as your internet ‘phone
number’ allowing other internet phone users to locate and call you. When VideoLink
registers with the Gatekeeper, it will send you an email requesting that you verify your
location. This is a security feature that prevents other Internet users from pretending to be
you. Your email address will not be used for any purpose other then as a phone number
for Internet Phone calls. It will not be added to any other database or mailing list or be
forwarded to any other Internet site or company.
This service is provided free from Smith Micro. The Gatekeeper is a server provided by
Smith Micro that all VideoLink users must register with. Your VideoLink software is
configured to use the Gatekeeper service by default.
You may disable Gatekeeper access if you like. However, doing so will require that you
know and enter the IP address of the person you are calling before you can connect to
them. If you do not know how to get their IP address, then you should leave the
Gatekeeper enabled and provide your email address in the User Identity panel of the
VideoLink preferences.
See the section Changing Internet Options Preferences to learn more about setting
preferences regarding the Gatekeeper.
GATEKEEPER SECURITY
The server is maintained in secure environment ensuring that uninterrupted service is
provided 24 - 7. Smith Micro personnel do not have access to view any messages or
content that is streaming through the Gatekeeper server. This server environment
replicates other connectivity type services, such as major Internet Service Providers, local
and long distance carriers.

FREQUENTLY ASKED QUESTIONS
In addition to the Help Center, we have provided this FAQ to aid you in the use of
VideoLink. Please browse this FAQ as well as the Trouble Shooting section for the
answers to your questions before contacting Technical Support.
Q) Do I have to be connected to the Internet to make or receive a call using VideoLink?
A) To place a call to someone using an email address you must be connected to
the Internet. However, you do not need to be connected to the Internet if you are
in a LAN environment and want to place a call to another VideoLink users using
his IP address.
Q) I connect to the Internet through a dial-up connection with a modem, so my IP address
changes. Will this cause a problem when someone tries to call me?
A) No, this is why we require VideoLink users to use the Gatekeeper (a free
service) for communications via the Internet. The Gatekeeper keeps track of your
email address and current IP address, so that anyone can call you while you are
connected to the Internet.
Q) What type of connection do I need to maintain a smooth and clear call?
A) 56K modem users will experience slow frames rates during a Video
Conference call. For this reason we recommend a broadband Internet connection.
Q) Will VideoLink automatically connect to the Internet to listen for calls?
A) No, VideoLink will not automatically connect to the Internet to listen for calls.
It will only initiate a connection to the Internet if you attempt to place a call and
are not already connected. It will only listen for calls when currently connected.
This is so that if you purchase Internet access monthly in specific packages (15
hours, 25 hours, etc.), you do not waste connection time while away from your
machine.
VideoLink Users Guide Smith Micro Software Inc.
29
Q) Is VideoLink based on any type of standard?
A) Yes, VideoLink is a fully H.323 v3 compliant Internet communications client.
This means that you will be able to communicate with any other H.323 compliant
Video Conference client regardless of platform or vendor. The following
standards are supported:
Audio – G.723 and G.711
