6. Get the best out of your Video Phone
There are a few steps you can take when setting up your room and using the
videophone to ensure that you get the best results:
6.1. Lighting
As with conventional photography, correct lighting is vital for achieving the best
results from your videophone. Make sure your face is well lit, preferably from the
front, and avoid having lights behind you that might shine into the camera lens.
6.2.LCD viewing angle
Correct LCD angle is essential to obtain the proper colors on the self view and
configuration screens. Move GVC-3000’s LCD so that it is perpendicular i.e. at 90
degrees to the phone’s keypad to get the best out of the phone.
6.3. Movement
Too much movement tends to result in a jerky picture. Avoid having a lot of
movement in the background. This doesn’t mean you have to sit completely still:
just move naturally, but be aware that if you wave your arms around, the person
you are calling may see a jerky picture. Remember too that a small movement near
the camera is just as bad as a big movement at a normal distance.
If you have something very detailed to show, you can send a clear still image using
the “Video Privacy” key. When the call is active, hold the clear still image before
your camera and press “Video Privacy” key so that the image is transmitted to the
person you are talking to. You can press “Video Privacy” key again to send your
video.
6.4. Sound
Where possible, it is better to choose a quiet environment than a noisy one. In very
noisy situations you will find the handset more effective than hands free.
26
Page 27
GVC-3000 User Guide
6.5. Connecting to a TV
Although the built-in LCD screen is ideal for individual use, you may find it useful
in some situations to display the pictures on a TV screen. For example, it is more
convenient to use a TV if several people need to see the screen, or if you are using
an MCU (Multi point Control Unit) to conference with more than one caller, with
video from several sources on the screen.
6.6. Before making a Call
Use the local view image to check that the camera is pointing where you want it to
and that it is in focus. If necessary, adjust the camera brightness, sharpness and
contrast to give a good picture. See the section on “Video Properties” for details on
how to adjust the sharpness, brightness or contrast of the local video image.
27
Page 28
GVC-3000 User Guide
7. Making and Answering Phone Calls
7.1. Handset and Speaker modes
During a call, audio-in can be through two modes, namely, the traditional handset
mode or hands free (speaker) mode while audio-out can be through handset,
hands free or through TV.
If handset mode or hands free mode is the only active mode, then both
audio-in and audio-out would be through the same mode.
Whenever both handset and hands free modes are active, then audio-in
would be through handset only.
Audio-out at any time would be through all the modes active.
Note:
• The active hands free mode (speaker) gets automatically turned off, when
handset is picked up or when the call gets terminated.
7.2. Making Calls
You can make a call in two ways:
1) Manual Dial :
Go off-hook by lifting the handset from the cradle or, by switching on the
speaker to get the manual dial screen. Here, you can enter your contact’s complete
URI (User ID, Domain and Port) or the speed dial number associated with any of
your known contacts followed by speed dial key sequence to make the call.
Numeric and Alpha-Numeric modes:
You can toggle between Numeric and Alpha Numeric modes while entering
your contact’s details depending on the context. In numeric mode only digits (0-9)
can be entered, while in Alpha-Numeric mode, any character acceptable in the
field can be entered. This is to facilitate easy and fast entering of numeric phone
numbers.
Please note that ‘*’ and ‘.’ can not be entered when you are in numeric mode and the
modes are dynamically changeable.

Already in Call:
If you are already in a call then to make a second call you will have to tap
the hook-flash ( press and release the hook in quick succession ) to get the
manual dial screen. This shall place the first call on hold and open the manual
dial screen to initiate second call.
The “dial” tone would be played at this moment and the corresponding line
LED would be light up. The moment you press one of the keys in the
alphanumeric keypad, you will no longer be able to hear the “dial” tone and
instead, you would be able to hear the “DTMF” tone of the digit you pressed.
You can place a call by entering the SIP URI or E.164 number of your
contact or the speed dial number that you have assigned to your contact.
a) Dialing a SIP URI :
i) Phone No: Destination SIP account number. For example, in
“[email protected]:5062” the phone number would be “user”.
ii) Domain: Destination SIP server. For example, in
“[email protected]:5062”, the domain would be “sipserver.com”. Note
that if this field is left empty, it is assumed that the destination that you
are trying to reach is registered with the same SIP server that you are
registered with. The sip server address and port would be used.
iii) Port: For example, in “[email protected]:5062”, the port is 5062. Note
that if this field is left empty, it is assumed that the port is 5060.
b) Dialing an E.164 number : The “Phone no” field should contain the E.164
number (normal telephone number) that you wish to dial. For example, you
can dial the E.164 number in one of the following formats, i.e., +123-45-
1234567, or, +123451234567.
c) Dialing a speed dial number : Dial Speed Dial Key sequence (*4) and the
speed dial number of your contact to place a speed dial call.

d) Redialing: Press OK key on the keypad without entering anything. The last
dialed number if exists shall be called out.
In Manual Dial screen, if the “Call” button is not pressed after one of the
alphanumeric keys is pressed, the phone (by default) will wait for five seconds
before sending all digits out and initiating the call. If no digits are entered for one
minute then your phone would timeout and the “Error” tone would be played out,
and the screen you were viewing previously would be shown.
2) You can make calls the easier way by selecting your contact from the phone
book entries or speed dial entries or from one of the call history lists. You can
reach one of these screens in three ways:
a) Go off-hook by lifting the handset from the cradle or, by switching on the
speaker. If you are already in a call then to make a second call you would
have to flip the hook-flash to get the manual dial screen. Press the phone
book icon or call history icon to get to the respective screen to
make the call.
b) Press the “Contact” key on the keypad.
c) Go to the main screen and, press the “View” button.
Once the call has been initiated, the main screen would be shown with
appropriate status messages; the “Progress” tone would be played out along with
the corresponding line LED blinking. When your phone attempts to establish a
connection, the “Ring back” tone would be played along with the corresponding
line LED blinking and the main screen displaying “Ringing” message.
When your contact answers your call, you can hear the other party in hands
free/handset mode as explained in “Handset and Speaker phone mode”.
If your contact is busy, the “Busy” tone would be played or, if call could not be
established due to some other reasons, the “Error” tone would be played along
with the reason for call termination on the OSD.

8. Configuration Guide
8.1. Before starting Network Setup
Please read this section carefully. There are a couple of things that YOU MUST
KNOW in order to setup your phone properly.
8.1.1.How you are connected to the Internet
(Identifying your Network Environment)
• PPPoE (ADSL) - ADSL stands for Asymmetric Digital Subscriber Line. It's a
type of DSL, where you connect to the Internet through an ADSL modem
(NOT your common dial up modem) connected to your common phone line.
You MUST be using an EXTERNAL PPPoE ADSL modem.
• DHCP - DHCP stands for Dynamic Host Configuration Protocol. If you are
connected through cable TV, this is what you're using. You are connected to
the Internet through a cable modem (NOT your common dial up modem)
connected to your TV cable.
• Fixed IP - This is commonly called LAN (Local Area Network). If all you have
is a jack in the wall or a long cable slinking up to your desk and no modem
(ADSL, cable, or dial up) in sight, this is probably what you have.
8.1.2.Pre-requisites to connect to your network
(Network settings)
• PPPoE (ADSL) - You must know your ID and password.
If your ADSL provider has provided you with a fixed IP address you must
configure your videophone to ‘Fixed IP (you must know your IP address, subnet
mask address, and your gateway address).
• DHCP - You don't need to know anything else.
• Fixed IP - Your IP address, subnet mask address, gateway address, and a
DNS server address.
35
Page 36
GVC-3000 User Guide
8.2. Network Configuration
You must know what type of network you are using first. Refer to “Before Starting
Network Setup” to see what network you are using.
The network configuration (Settings → Network Configuration) provides different
parameters to connect to your network.
8.2.1.Network Address Configuration
The Network Address screen (Settings → Network Configuration → IP
Configuration) asks for the information that is necessary to connect a GVC - 3000
call over the Internet. There are three types of network connections to choose
from: Static, DHCP, and PPPoE. If you do not know which to choose or you do not
have enough information to complete this section, please contact the ISP (Internet
Service Provider) or Network Administrator for assistance.
36
Page 37
GVC-3000 User Guide
STATIC
Choose Static when connecting to a broadband connection that offers static IP
addressing or when behind a router that does not have a DHCP server enabled.
This choice requires the input of specific IP address information.
IP Address: Input the IP Address provided from your router configuration settings,
ISP, or network administrator.
Subnet Mask: Input the Subnet mask provided from your router configuration
settings, ISP, or network administrator.
Gateway: Input the Gateway address provided from your router configuration
settings, ISP, or network administrator.
37

GVC-3000 User Guide
Idle Timeout: Disconnects the PPPoE connection after “timeout” minutes.
Maximum value that can be configured is 86400 seconds. Configuring a value of
zero does not disconnect even when there is no activity.
8.2.2.DNS Configuration
The DNS* screen (Settings → Network Configuration → DNS Settings) asks for
information regarding the Domain Name System (DNS) server. If you chose static
IP on the Network Address screen (described on the previous pages), it would be
useful to provide the DNS Primary Server settings. If you chose DHCP or PPPoE
modes on the Network Address screen, these values can be left blank as they are
obtained from the server.
You should be able to get both of these settings from your router configuration
settings, ISP, or your network administrator. Only the primary DNS server address
is required, though it is best to have both the primary and secondary addresses.

Press “Upgrade” to fetch the firmware files. If the configured upgrade server is
found and new code images are available, the GVC - 3000 phone will attempt to
retrieve the new image files by downloading them into the phone’s memory.
After the initial version file is downloaded, OSD shows a list of firmware versions
available on the server for you to select. Upgrade to a higher version and
downgrade to a lower version are both supported by the device.
Once the Versions are available for upgrading, you can scroll down and select any
of the versions and press Upgrade to initiate the upgrade.
GVC – 3000 would then initiate the upgrade with the selected version. The version
file shall be downloaded into the phone’s memory.
Upon verification of checksum, the new code image will be saved into the Flash. If
firmware upgrade fails for any reason (e.g., FTP/HTTP server is not responding,
there are no code image files available for upgrade, or checksum test fails, etc), the
GVC - 3000 phone will stop the upgrading process and simply boot using the
existing code image in the flash.
Firmware upgrading may take as long as 45 minutes over Internet, or just 5
minutes on a controlled LAN. It is strongly recommended to conduct firmware
upgrade in a controlled LAN environment whenever possible.

image of the old firmware. You need to perform an upgrade again to achieve the
latest version.
WARNING!!! All active calls would be disconnected on initiating firmware upgrade
and no configuration / calls can be made until Software upgrade is over.

Translation). Go to Settings → Network Configuration → NAT Traversal and
enter the Videophone’s public IP address, which is given to you by either
your ISP or network administrator.
