2 Special Notes
WoIP-8 is a newly introduced model that supports voice calls via a 3G Cellular Network (UMTS-WCDMA and
GSM). It operates at the frequencies specified below.
1. UMTS (WCDMA/FDD)：850/900/1900/2100 MHz
2. GSM：850/900/1800/1900 MHz
Since WoIP-8 operates at slightly different frequencies than those used in GoIP-8 (2G), the antennas supplied with
the WoIP-8 cannot be replaced with the one used in the GoIPs. Otherwise, WoIP-8 may encounter poor signal
reception which causing poor performance. Please note that the antenna for WoIP-8 is about 4 inches long and the
one for GoIP-8 is just 2 inches long.
The device configurations for WoIP is in general the same as those in GoIPs.
3General
3.1 Introduction
GoIP and WoIP are abbreviated from GSM over IP and WCDMA over IP respectively. They are new types of
VoIP gateway that allows call terminations from a VoIP network to cellular networks and vice versa. Call
connections between IP networks and cellular networks are now bridged seamlessly to extend the voice
communication coverage significantly. As the traditional PSTN lines are starting to disappear in developed
countries and are not going to be built extensively in under-developed countries, GSM/WCDMA phones are
getting more and more popular all over the world with lower and lower service charges, the emergence of
GoIP and WoIP bridge the gap between the traditional telephone networks and VoIP networks as shown in the
diagram below. As a result, local and worldwide voice communications are more convenience, lower cost,
and broader coverage.

You can now make a call from anywhere in the world via a VoIP network and then terminate the call via a GoIP
/ WoIP to the local telephone network (PSTN). On the other hand, you can also make a call from the local
telephone network to a GoIP / WoIP (the GSM phone number) and then dial another number via a VoIP
network to anywhere in the world. In these two cases, a VoIP Service provider is required for one side of the
call termination. For two fixed locations, it is possible to setup GoIPs at both ends for call terminations
without subscribing to a VoIP Service provider.
GoIP / WoIP can also be used to achieve GSM roaming via VoIP. The idea is to route all your incoming GSM
calls to a GoIP / WoIP via call forward or simply insert your SIM card to a GoIP / WoIP. You can then setup the
GoIP / WoIP to forward all incoming calls to another GSM number in the world via a VoIP service provider.
The charge per call from a VoIP service provider is significantly lower than the roaming charge.
For office environment, GoIP / WoIP offers a quick way to replace the traditional PSTN lines or T1/E1 lines to
your IP PBX. There is no initial installation/reallocation charge and no need to wait for installation.
Depending on our usage, you can add or remove lines as per your requirement. You can even configure the
system so that everybody calls the same number regardless the number of lines available.
Throughout this manual, GoIP or WoIP is referred as “the device”.

3.6 LED Indicators
LED indicators (shown above for GoIP-8) are used to show the current status of the device. They are often used
to determine if the device is working normally or not.
LED Label
Description
Power
This LED is red and illuminates when power is connected.
LAN
This LED is red and illuminates when the LAN port is connected and blinks when data
transmission occurs.
PC
This LED is red and illuminates when the PC port is connected and blinks when data
transmission occurs.
RUN
This LED is green and blinks at a rate of every 100ms when VoIP is not ready for
making calls. (Fast Blink)
It blinks at a rate of every second when VoIP is ready for making calls (Slow Blink).

Channel “x”
Each cellular channel has its own status LED and its color is green.
1. It blinks at a rate of every 100ms (Fast blink) when the corresponding cellular
channel is not yet registered to a GSM network.
2. It blinks at a rate of every second (Slow blink) when the corresponding cellular
channel is ready for making or receiving calls (registered to a Cellular network).
3. It illuminates when cell call activities occur (in use, ringing).
4Installation
The same installation procedure applies for all models with the differences in the number of channels (ports)
available and the SIM card insertion. It is important to note that the power to the SIM slot MUST BE
disconnected/removed before removing or inserting a SIM Card.You can either disconnect the power to the
device or disable each GSM channel individually via the web interface.
1. SIM card slots are located either at the bottom (for old hardware) or at the back (for new hardware) of the
main unit.
For the models with the SIM card slots located at the bottom, you need to open the bottom SIM cover in
order to install SIM cards. First slide the metal clip to the direction as indicated on the top of the clip.
Insert a SIM card to each slot carefully and then place the metal clip back in place.
For the models with the SIM card slots located at the back, just insert a SIM card to each slot as shown in
the drawing on the right. Please make sure that the orientation of the SIM Card is correct before
inserting the card.
For GoIP (1-channel), the SIM card insertion orientation is shown in the figure on the right. The metal
contacts must face down and the cut corner is inserted first.
For GoIP-4 and GoIP-8, the SIM card insertion orientation is
shown in the figure on the right. The metal contacts must
face up and the cut corner is inserted first.

10
For GoIP-16, the SIM card insertion orientation is shown in the figure below. The cut corner is pointing
downward with the metal contacts facing the front of the GoIP.
For GoIP-32, the SIM card insertion orientation is shown in the figure below. The cut corner is pointing
downward with the metal contacts facing the front of the GoIP.
