5 IP Telephony
Introduction to IP Telephony
IP telephony, namely voice over Internet Protocol (VoIP), is also called broadband telephony or
Internet telephony. It utilizes Internet Protocol (IP) network technologies to implement voice
communication. During a VoIP call, voice signals are digitized, encoded, packetized, and transmitted
as packets over a network. On the receiving side, the packets are then decoded, and digital signals
are converted to reproduce the original voice streams, which can be heard by the called party. Different
from traditional PSTN calls, VoIP calls are transported over IP networks, meaning voice streams are
transmitted over users' existing broadband Internet. This makes full use of broadband resources.
Configuring VoIP
The HG552e supports VoIP. You can place VoIP calls after your phone is connected to the PHONE
port on the HG552e.
To use the HG552e to place VoIP calls, ask your network service provider to activate VoIP
services for you. By default, your network service provider will have all related parameters,
such as the VoIP account and address, set for you. You will not need to configure any settings
to place VoIP calls.
Placing a VoIP Call
Once your network service provider has activated VoIP services for you, you will be assigned a VoIP
account, which is also your VoIP call number.
Before placing a VoIP call, ensure that the HG552e has connected to the network. When the call is
established, your VoIP call number is displayed on the called party's phone.
For VoIP call tariffs, contact your network service provider.

8 FAQs
What Can I Do If I Cannot Open the Web Management Page?
1. Open Internet Explorer. Choose Tools > Internet Options > Connections > LAN settings,
and ensure that all check boxes are deselected.
2. Check that the computer IP address is 192.168.1.*. (* is any integer from 2 to 254.)
3. Check that the cables are securely connected to the HG552e and that the LAN port's
indicator is on.
4. Ensure that the user name and password are correct.
If the problem persists, restore the HG552e to its default settings.
What Can I Do If the HG552e Cannot Access the Internet through a
Wireless Network Adapter Sometimes or If the WLAN Connection Is
Unsteady?
This is probably because the HG552e has its cables connected loosely, is placed too close to
electronic appliances with intensive interference, or is too far from the computer. Verify that:
1. The power and telephone cables are correctly connected to the HG552e.
2. Your computer and the HG552e are far from electric appliances that generate strong
magnetic or electric fields, such as microwave ovens, refrigerators, and cordless telephones.
3. The HG552e is in an open area, and there are no obstacles, such as concrete or wooden
walls, between the HG552e and computer.
4. The HG552e is close to the computer.
5. The angle between the HG552e and computer is appropriate.
Do not use the HG552e during thunderstorms, as the signal strength may be unsteady and
the HG552e itself may be damaged due to lightning strikes.
What Can I Do If I Cannot Access the Internet?
1. Check that the Power indicator on the HG552e is steady on. If the Power indicator is off,
perform further checks as follows:
a) Check that the HG552e is turned on.
b) Check that electricity comes from the socket and that the power input from the socket
meets the requirements described on the label of the HG552e's power adapter. If the
voltage is unstable, for example, if the voltage is too high or too low, do not use the

b) In the Computer Management window, click Device Manager.
c) In the right pane of the Computer Management window, click Network adapters.
If no network adapter is found or if a question mark (?) or an exclamation mark (!) is displayed
next to the network adapter icon, the driver for the network adapter is not correctly installed.
Re-install the driver.

7. Check that you can use the PPP dial-up software to set up dial-up connection. If the dial-up
connection fails, perform further checks as follows:
a) Close the PPP dial-up software, and power off the HG552e. After 5 minutes, power on
the HG552e, and use the PPP dial-up software to dial again.
b) Restore the HG552e to its default settings.
If the problem persists, contact your network service provider.
