A VoIP gateway is used to create a bridge between the worlds of legacy telephony and VoIP.  Gateways are typically utilized to join legacy phone systems (PBXs or ACDs) with VoIP resources or to connect modern VoIP phone systems with legacy phone lines.

The GSM Gateway connects to the legacy system through each analog or digital trunk port.  The PBX sees the gateway as either the phone company or as a different networked PBX. Other methods for VoIP gateways include staged movements, where the gateway acts as a bridge between the PSTN, a legacy PBX, and a new IP PBX.

Gateways come into several formats. Analog gateways convert between VoIP protocols and regular analog phone lines and/or phones. Digital gateways convert between VoIP and various kinds of digital phone services: T1, E1, PRI, and/or BRI, depending on the gateway.

Know the types of VoIP Gateway Before Buying

VoIP is penetrating various industry sectors as a modern way for conducting business communication. It is not only available at a lower cost but also has many advantages over traditional phone-based communication. VoIP integrates almost all multimedia-based applications, surveillance, video conferencing, etc. for effective collaboration that results in a Unified Communication System.

In the below paragraphs, we will see are different types and kinds of VoIP Gateway. And, that sort of businesses, it (any) is suitable.

VoIP as a whole is comprised of many hardware. One of them is VoIP Gateway. It is also known as PSTN Gateway. PSTN stands for Public Switched Telephone Network. VoIP Gateway converts telephony traffic into IP traffic. By this conversion only, it's possible to transmit telephony traffic over a knowledge network using the web . Basically, there are two types of conversion.

Conversion of incoming PSTN Lines into VoIP

Through this method, a regular or existing telephony network is leveraged for converting it wholly into an IP telephony network. In such a case, the VoIP gateway lets users receive and place regular telephony networks over the Internet.

Connecting Traditional PBX based Phone System into IP Network

With this method or approach, VoIP service provider plays a huge role in making and receiving calls via VoIP Gateway. D note that in this approach, VoIP gateway acts as an external unit; it has a connector that connects IP network and traditional phone lines via ports available in VoIP Gateway.

Which one can best suit you?

In most business communication based on VoIP, the first approach is preferred. As the first one allow businesses to continue using their existing traditional phone lines with a guarantee of quality call quality and higher availability.

In contrast, the second one is preferable for businesses that have multiple offices at multiple locations. Because of such an approach calls can be routed via the internet to reduce internal communication costs significantly.

Two Different Types of VoIP Gateways

Analog units

As the name says, Analog VoIP Gateway works with analog signals. It has the ability to connect analog phone lines to a VoIP gateway. Generally, they are made for 2-24 lines.

Digital units

Once again, as the name goes, Digital VoIP Gateway works via digital lines or circuits. It has either: BRI ISDN lines, PRI/E1 lines, or T1 (Fibre optic) lines. Basically, Integrated Services Digital Network (ISDN) is a set of communication standards. It guides the simultaneous transmission of digital voice, video, data, and other network services over the traditional circuits of PSTN. It defines several kinds of access interfaces like BRI, ISDN, PRI, etc.

ISDN BRI and PRI both use existing telephone infrastructure. However, the basic difference lies in the performance. PRI is superior to BRI. Because PRI uses multiple channels and lets businesses configure for adjusting the bandwidth need. In contrast, BRI has only one channel.

PRI is preferable to medium and enormous enterprises due to the speed and adaptability . And, BRI for small and micro-businesses. However, BRI is getting phased-out from the market due to the superior benefits of PRI and most importantly its cost competitiveness (though its cost is higher than BRI).

VoIP GSM Gateway

VoIP GSM Gateway is employed for routing IP, digital, analog, and GSM networks directly. So, with GSM Gateway, businesses let the Least Cost Routing (LCR) come.

Thus, with this businesses can reduce their expenditure on telephony. It serves the simplest to businesses where business communication calls from IP to GSM are regular. And, when business personnel is using SIM cards and GSM modules that are integrated for VoIP GSM Gateway then it further reduces the cost significantly.

VoIP GSM Gateway a minimum of Cost Routing is that the most cost-effective telephony communication approach.

Now, let us have look at analog-based VoIP Gateway. Analog-based VoIP Gateway are going to be required (for your business) when at current times Analog phones are getting used .

Before we move ahead, i would like you to understand that basically FXS and FXO are just the ports. Also, do note that FXO and FXS always come in a pair like male / female plug. And, in cases of VoIP System without a PBX, the phone can be directly connected to the FXS port. It is used to enhance analog phone lines.

FXS stands for foreign exchange subscriber interface. Its role is to deliver the analog line to the subscriber. In layman language, it a sort of “plug on the wall” device for delivering users a dial tone, battery current, and ring voltage. On another hand, FXO – exchange Office interface receives the analog line. It adds a plug on your business phone or fax machine to deliver a loop closure (on-hook/off-hook indication.

FXO Gateway

As said earlier, your business will need FXO Gateway so as to determine a connection between analog phone lines and an IP phone system. With FXO Gateway, you'll also connect the FXS port to the FXO port. it's done to translate the analog telephone line into a VoIP call.

FXS Gateway

FXS Gateway utility lies in connecting traditional PBX phone lines with a VoIP phone system or VoIP service provider. Also, businesses can leverage it to attach analog phones with a VoIP phone system. the sole situation when a business will need an FXS gateway is to attach FXO ports to the web or IP Telephony system.

In a nutshell, it many much depends on the prevailing (or opting for) phone lines on which your business communication is predicated on. If it's analog, then you would like an Analog Gateway. However, if flexibility may be a preference then Digital Gateway is your need. And, if technology, also as cost optimization, is needed, then LCR (GSM Gateway) should be thought of or given a preference. Nevertheless, it's a troublesome job to research by self for selecting the proper VoIP System and related products like VoIP Gateway. But, don’t worry and avoid hassles by taking the assistance of VoIP experts like Cohesive Technologies. Know more about the best-fit VoIP Gateway for your business by consulting with the experts.
