8-port GSM-gateway ALLVoIP AV3803

Anyone who is used to monitor spending and generally know how to count money, he knows that mobile communication is used in an uncontrolled, on occasion, and without, can become a very significant expenditure, especially in a company-wide. When it comes to corporate use of mobile communication, it is considered that its cost should worry about the company itself, choosing the operator, the most appropriate charging scheme, and instructing employees on conditions of use of telephone for personal purposes. Of course, it gives some results, but by no means suggests that communication costs are optimized and can not be radically reduced. Probably every occasion to use the services of "alternative" long-distance and international communication. By purchasing a card and call the number listed on it is possible to talk of, say, from Moscow to Vladivostok on the local rate plus rate of the company, issued the card (using IP-telephony to transfer your call), which ultimately turns out to be cheaper than the tariff fixed-line operator, or the more mobile.

The benefit is obvious, that's just not very convenient to use - and the process of dialing, and the need to purchase the card, again the choice of the company providing such services (IP-telephony operators in recent years far more than the companies that provide wireline or wireless connection). In general, we need to perform a set of actions, and there is quite a logical idea, why for IP-telephony have to pay significantly more than the cost traffic, unless you arrange their own voice? Without specialized solutions do this, perhaps we could, but it is very difficult and unprofitable, and therefore can hardly be neglected proposed equipment, the more that it is available, easy to deploy and use, simply integrated into the corporate infrastructure. It says everything about the GSM-gateway ALLVoIP AV3803, the further the story will follow this decision.
Scope of delivery, the main characteristics and features

Appearance ALLVoIP AV3803 immediately gives a professional designation device. Designer delights can be considered unless the choice of colors for painting the metal case. Small in size, it is almost completely painted a pleasant shade of aquamarine, only the front panel and back side of the light, almost white. The front panel contains eight slots for SIM-cards, they are placed in four groups of two slots and are equipped with LED indication of the link. Another indicator in the lower right corner of the panel indicates the presence or absence of food.

I must say that in a quiet room on the availability of food excellent report and the noise of the fans, two of them and both are located on the back of the chassis. Between the fans are connectors for external antennas, they are two, despite the fact that the device is set up to 8 SIM-cards. Thanks to the built-adder, two antennas is more than enough to serve 8 transmitters.

On the left, in the well is located connector for power supply and port network interface through which the gateway ALLVoIP AV3803 is connected to the corporate network and the Internet.

Complete set of the device to expectations: no nonsense, a kind of necessary and sufficient equipment. In a modest gray box contains the following components:
Sam gateway ALLVoIP AV3803,
Power supply
Power cable,
Network cable with RJ-45,
Two small antennas GSM.

It is noteworthy that in a set of 2 antennas, the number of inputs for connection, although the channels at the gateway 8. I must say, ALLVoIP AV3803 quite effectively uses these small antennas and provides reception quality is much better than conventional mobile phones. Where the mobile phone shows the 1.2 "sticks" to the signal strength indicator, GSM-gateway works confidently and evaluates the signal as a good and stable. Antennas may seem fragile, because they have a small footprint, but everything is simple - they are magnetic and can be safely installed on the body lock or any more stable steel facility.

To start with ALLVoIP AV3803, you must install the SIM-card (or cards, up to 8, which side of their set - shown in the picture-prompt for each pair of slots), connect the network interface to the LAN or to configure, directly to your computer, connect the antenna and connect to ALLVoIP AV3803 power adapter. Fans will begin to rotate, creating a rather loud but not annoying hum, in principle, if the gateway does not put in the server, and a working office, interfere with the work he will not, though, the room more comfortable will do. LEDs on the channels of the link will flash on when a communication (calls to any gateway of the rooms) to include an indicator of the channel. You are ready to set up for later use, how to do it - we now detail closer look.
