How does a VoIP GSM Gateway work?

How is a signal transmitted from IP networks to cellular networks using a GSM VoIP gateway

VoIP-GSM gateway is also called SIP-GSM gateway. It is a device that is responsible for the live broadcast of the signal from the IP network to the cellular network, and then back again. Through this process of saving mechanisms are consistent and they are implemented through the use of GSM-gate together with office systems, which are based on VoIP-technology.

Voice Gateway is set to reduce the more intelligent use of your company&#;s spending on . If you select the appropriate tariff for your company, then it will reduce the cost of telephony by approximately 30%. If that call-center or some other organization, which for the most part a lot of calls, then this is a very significant savings.
However, using the GSM gateway is explained not only by economic considerations but also functional. Many of the useful features are not available with standard PBX. Inside the company, communication will be carried out much faster, but in the end it will be an indicator of quality in the competition of various companies. Especially if this is functional in taxi services, internet commerce. Service Food and various other services.

Types of VoIP GSM gateways

• Single-channel gateways. They are intended for home or small office. They allow you to call in GSM networks, using conventional landlines, or the office IP-ATC.
• Multi-channel gateways. These gateways are corporate clients. Gateways are the most high-performance and can simultaneously support several dozen involved SIM-cards. Corporate gateways are often used by large call-centers that call on customers&#; mobile phones.

VoIP GSM Gateway works

Any gateway must be connected to a PBX company. At the same time, it does not matter who is the manufacturer of your PBX type and how you use it. For any kind you can pick up your option gateway. This must be connected to the gateway internal and external urban lines. For everything to work, you must configure table rules:

1. Favorable calls within the country. To begin with, the company enters into a contract with the provider SIp telephony. In fact, most conventional service providers also offer services to SIP, but this is not always known. So, it is not necessary to look for some mysterious providers sufficiently clarified in an existing one, whether it offers such services. Then all calls that start intercity codes beginning to get on the VoIP gateway. That is, if you type in the code of another city, then for the number, the call initially falls on the VoIP gateway, and only then to the end user. The gateway converts your call from the PSTN to the Internet, and thus it is already charged at the rates SIP-telephony provider. Significant savings are achieved due to the fact that tariffs from the SIR providers flexible enough, and everyone can choose the most convenient for themselves, as opposed to the standard telephony.
2. Favorable international calls. The rule of international calls is the same as on the inside. Most providers have a SIP connection rates are much lower than fixed-line operators.
3. Favorable calls to mobile phones. All calls that start codes of the mobile operator, must pass through the VoIP GSM gateway, and get on the SIM-card operator. Then the call is already on the specific corporate rate, which is set by the mobile operator.

Review of telephony gateways

We noticed that every individual is different gateway functional characteristics, but they all have their own characteristics and the basic common features that we describe here:

• The capacity of the equipment. It may be different as a single-channel and multi-channel. If you have a very high traffic. then you can opt for the eight-telephony gateway. That is, one number at a time can get through 8 people
• A variety of designs. The gateway can be installed simply on a table, or let&#;s say. placed in the telecommunications rack. Then, its dimensions should be 19 inches
• Interface to connect to the PBX. It can be both digital and analog
• Supports SIP protocols
• The presence of a variety of security features such as access control lists, user authentication, etc
• Receiving and sending faxes. In addition, you have the ability to connect an analog fax machine
• Subscribe and receive SMS. But in most cases this will require special software
• Maintain a variety of functions. Often this is call forwarding, voice recording greetings, collecting call statistics
• The configuration is done via the web-interface
• Firmware, which is constantly updated
• Function Call back

Types of telephony gateways

Voice telephony gateways can be of various types, and to you it was easier to determine which gateway is needed for your company, give their response here:

• VoIP gateway &#; a device that allows you to convert the PSTN voice traffic in the Internet (data network)
• GSM gateway &#; it allows you to transfer traffic from the fixed network supporting mobile standards GSM. The same principle works for other gateways, but they are not widespread. This CDMA and UMTS gateways devices
• VoIP GSM Gateway &#; its function is to transfer voice traffic from the Internet directly to the network operator&#;s mobile standard, GSM. And it can also work in reverse.

What is a VoIP gateway?

A VoIP gateway is, at its simplest, a device &#; or bridge - that converts call traffic into data packets to be transmitted over the internet.  

This happens in one of two ways:

1. When the call traffic originates from a Public Switched Network (PSTN) and needs to be converted from an analog voice signal into a digital one. The digital signal is then compressed using what&#;s known as a &#;codec&#; and broken into a series of &#;data packets&#; that are transferred across the Internet Protocol (IP) network. 

2. When the call traffic originates from an IP network, then the VoIP gateway will decompress the data packets into a digital signal that&#;s then converted into an analog signal to be sent across the PSTN.

These data packets are the lifeblood of any internet call system as they dictate call quality &#; data packet loss can result in poor quality calls that frustrate employees and customers alike and can even have a negative impact on your business. 

With traditional systems, one call is converted at a time, whereas with a VoIP gateway, multiple calls are supported simultaneously, increasing call capacity for busy companies. 

VoIP gateway systems typically include the following features:

&#; Voice and fax compression / decompression

&#; Packetization and control signalling management

&#; Call routing

&#; External controller interfaces

Why was the VoIP late to the meeting...? It got hung up in traffic!

You can always tell when a new piece of tech becomes commonplace &#; the corny jokes start doing the rounds!

And it&#;s easy to see why VoIP has recently followed this well-trodden path given our remote ways of working since . 

But what about a VoIP gateway? It&#;s perhaps a term that is less common right now but is likely to see increasing usage in the coming months and years as more and more companies continue to switch to digital systems and look for ever more efficient ways of managing call traffic.

In this article, we&#;ll set out what a VoIP gateway is, how it works, what the different types of gateway are, and how to set one up.

VoIP gateways offer many benefits, the biggest of which is the ability to spread out and manage costs more effectively.

VoIP gateways have many benefits, especially for businesses transitioning from one type of call system to another. 

With VoIP gateways, you can, for example, migrate in phases, keeping your existing hardware in place to keep new costs down. By using existing equipment, you subsequently reduce training and set-up times for your teams.

The biggest benefit of a VoIP gateway is, therefore, one of cost. Changing over an entire office or organization to VoIP can be costly &#; in addition to the cost of new equipment, there&#;s the infrastructure and IT support costs to factor in too. With a VoIP gateway, however, these costs are more easily managed and can be spread out over a longer period of time &#; something most Finance Directors and CFOs will be very glad of!

What&#;s more, you can choose a VoIP gateway system that optimized for minimal or &#;Least Cost Routing&#; by directing specific calls to the provider that will charge the least per minute.

In addition to this, VoIP servers can and often fail. VoIP gateways, however, have what are called &#;fallback&#; modes that switch to the PSTN if the internet is down.

What a lot of businesses opt for nowadays is a &#;hybrid&#; approach that combines on-site equipment with VoIP gateways. This enables them to get many of the advantages of VoIP while still retaining their existing infrastructure and equipment that they know to be reliable and familiar.

Oh, and watch out for what are called &#;Fully Hosted IPBX systems&#; &#; they&#;re also a growing trend nowadays as they offer a full telecommunication system without the hassle of buying and managing additional hardware. However, if for any reason you lose your connection to the hosted IPBX, you lose the ability to make both internal and external calls.

What are the different types of VoIP gateway?  

There are two main types of VoIP gateway, analog and digital. 

Analog 

As the name suggests, an analog VoIP gateway is used to connect your traditional analog telephones to a VoIP system, or to connect your VoIP system to the PSTN. These gateways are typically available for between 2 and 24 lines and come in two different forms, both of which often appear as &#;media gateways&#; to:

• FXS (Foreign Exchange Subscriber) gateway &#; used to connect your traditional telephones (and fax machines) to a VoIP system.
• FXO (Foreign Exchange Office) gateway &#; used to connect your VoIP system to your PSTN lines.

Digital

Once again, the clue is in the name! Digital gateways are used to connect your VoIP system to your digital voice lines &#; either BRI ISDN lines (for Europe), PRI / E1 lines (for Europe), or T1 lines (in the US).

 Other terms it&#;s worth knowing about when exploring VoIP gateway solutions are:

VoIP GSM Gateway

GSM stands for Global System for Mobile Communications and is used for routing IP, digital, analog, and GSM networks directly. With these devices, companies can take advantage of the &#;Least Cost Routing&#; option that we mentioned earlier.

PSTN Gateway

A PSTN (Public Switched Network) gateway is a third-party hardware component that converts signalling and media between the Enterprise Voice infrastructure and the PSTN, either directly or through connection to SIP trunks (more on SIPs and SIP trunks here).

It very much depends on your existing system as to which gateway solution is best. If you&#;re currently running on analog, then you&#;ll need an Analog Gateway. If you want to upgrade on flexibility though, then you should consider a Digital solution. And if cost optimization is high on your priority list, then it&#;s worth exploring the VoIP GSM Gateway option.

How do you set up a VoIP gateway? 

 Setting up a VoIP gateway should be done by your IT administrator or external supplier.

The specifics of setting up and configuring a VoIP gateway will very much depend on the system you have. You&#;ll usually be able to find detailed instructions with your supplier either via their website or their support line. For example, beroNet, one of the most popular gateway solutions, explain their beroNet configuration process online. Or Grandstream, another supplier, has their own detailed set-up instructions for Grandstream gateways online.

The basic steps are pretty similar across solutions.

What you&#;ll need before getting started:

• An internal device with external connectivity through VoIP via the Internet.
• The PSTN interface to a network, with IP connectivity to an in-house VoIP system.
• Both PSTN and VoIP interfaces externally.

Steps to follow to setup a VoIP gateway:

Step 1

Find and note the gateway&#;s network IP.

Log in via the device&#;s web interface and update your firmware to the latest version.

Assign a static IP and note it down.

Step 2

Configure the VoIP gateway in your admin or management console.

You can typically do this by clicking on &#;SIP Trunks&#; and then &#;Add gateway&#;. Here you&#;ll be asked for details such as the model, number of device ports and main trunk number.

You&#;ll also need to add the hostname or IP of the VoIP gateway and any Direct Inward Dialling (DID) numbers.

Step 3

Once you have created the VoIP gateway connection, you&#;ll need to generate a device config file. Depending on your solution, that will either configure remotely or download a file to your computer. If the latter, you&#;ll then need to upload these to the gateway.

Step 4

Your final step is to create &#;Outbound Rules&#; to route calls over the PSTN gateway. You can do this via the &#;Outbound Rules&#; function of your device.

You&#;re all set!

If at any point you get stuck, then contact your gateway device supplier or IT administrator.

Final thoughts

The telecommunications world has come on in leaps and bounds in recent years, with many businesses now relying on VoIP for their core operations. VoIP Gateway is additionally a common method for businesses looking to ease the transition to VoIP technology while still leveraging existing equipment and IT infrastructure. 

Pardon the pun, but it&#;s an excellent &#;gateway&#; to a much easier and more efficient VoIP system that helps to reduce IT costs and keep your business running. What&#;s more, the benefits of VoIP gateways make them a smart choice when trying to spread out upgrade costs while still retaining a professional, high call quality system.
