Before buying a one, know the types of VoIP Gateway


VoIP is penetrating in various industry sectors as a modern way for conducting business communication. It is not only available at 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 into Unified Communication System.

In below paragraphs, we will see what are different types and kinds of VoIP Gateway. And, for which type 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 is possible to transmit telephony traffic over a data network using the Internet. Basically, there are two types of conversion.

  1. Conversion of incoming PSTN Lines into VoIP

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

  1. ConnectingTraditional PBX based Phone System into IP Network

With this method or approach, VoIP service providerplays a huge role for making and receiving calls via VoIP Gateway. D note that in this approach, VoIP gateway acts like 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 of the business communication based on VoIP, thefirst approach is preferred. As the first one allow businesses to continue using their existing traditional phone lines with a guarantee of a quality call quality and higher availability.

In contrast, thesecond one is preferable by businesses that have multiple offices at multiple locations. Because by 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 an ability to connect analog phone lines to 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 circuit. 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 uses existing telephone infrastructure. However, the basic difference lies in the performance. PRI is superior to BRI. Because PRI uses multiple channels and lets businesses to configure for adjusting the bandwidth need. In contrast, BRI has only one channel.

PRI is preferable to medium and large enterprises because of the speed and flexibility. 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 used for routing IP, digital, analog, and GSM networks directly. So, with GSM Gateway, business let the Least Cost Routing (LCR) to come.

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

VoIP GSM Gateway at Least Cost Routing is the most cost-effective telephony communication approach.

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

Before we move ahead, I want you to know 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 FXS port. It is used to enhance the 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 kind of “plug on the wall” device for delivering users a dial tone, battery current, and ring voltage. On another hand, FXO – Foreign 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 in order to establish a connection between analog phone lines and IP phone system. With FXO Gateway, you can also connect FXS port to the FXO port. It is done to translate the analog phone 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 connect analog phones with a VoIP phone system. The only situation when a business will need FXS gateway is to connect FXO ports to the Internet or IP Telephony system.

In a nutshell, it many much depends on the existing (or opting for) phone lines which your business communication is based on. If it is analog, then you need an Analog Gateway. However, if flexibility is a preference then Digital Gateway is your need. And, if technology, as well as cost optimization, is needed, then LCR (GSM Gateway) should be thought of or given a preference. Nevertheless, it is a tough job to analyze by self for choosing the right VoIP System and related products like VoIP Gateway. But, don’t worry and avoid hassles by taking the help of VoIP experts like Cohesive Technologies. Know more about the best-fit VoIP Gateway for your business by consulting with the experts.


What is Power over Ethernet? Is it useful to my enterprise?

Blue network cable - curved

PoE and Coaxial cables are meant for different purposes. Both can’t be interchangeably used. While Coaxial cable is used to transfer low-level frequencies or as transmission lines, on another side, PoE (Power over Ethernet) is used to transfer a broadband signal between computers and other related devices. PoE was first introduced in 1980 to replace the wired LAN technologies. However, there is one important aspect of PoE.

PoE was made to comprise the two functions of a cable. Along with the transmission of data, it can also supply electric power to the connected devices or equipment. Thus, it is one fit cable to satisfy the need of network connection as well as power connection in a single cable. PoE is mainly used for low powered devices like PC, Laptop, Mobile Phones, VoIP products, IP Cameras, Surveillance equipment, ATM Machines, Intercoms, Vending machines, a recent entrant to utilize PoE is lighting, and much more.

PoE has a great role to play at business or enterprise off-site locations and offices. Going for two separate lines- one for network and another for power is only going to mess up your circuit as well as costs. Moreover, such has more disadvantages. Now, instead of briefing disadvantages of two separate lines, let us see the benefits of PoE.

Advantages of PoE

poe advantage

  1. Flexibility: As PoE eliminates the need for two separate lines, devices that are compatible with PoE can be easily moved from one place to another. All you need is a good PoE cables and PoE switch like Milesight 4K H.265 PoE NVR 5000 [MS-N5016-UPT]. Moreover, there is no AC power constraint in the whole picture.
  2. Scalability: As PoE supply electric power (along with data transfer), installation, distribution and more importantly expansion of network connection at your enterprise location is easy, simple, fast, and requires marginal investment. Thus, as your business grows and demands upgraded the network with PoE, it’s easy at lower costs. This advantage is also applicable for creating a temporary network deployment like at trade shows, meetings, virtual classrooms, etc. PoE is as simple as Plug-N-Play.
  3. Safety – POE safeguards your network based equipment from electric overload as PoE works with low voltage requirement.
  4. Reliability: POE it lets Centralized Power Management arrive at your enterprise location. PoE eliminates the need of distributed UPS replacing it with centrally managed single UPS. Moreover, along with the above factor and as PoE works with standardized, universally accepted, and compatible Adapters, network equipment can be easily backed-up by the continuous power supply of your office. And let you disable or reset devices without any special skills. Further, PoE obliges to IEEE’s 802.3 standards.
  5. Savings of Time and Money: Money is saved by eliminating two circuits (electric and network) and for such, the hiring of skilled personnel for maintenance and repair is no more a scenario. With this, time savings, too.

PoE is one of the advanced cable technology. It has several benefits for your business or enterprise offsite as well as offices. Without any doubt, it is essential for growing businesses as it is flexible, scalable, reliable, and comes at a lower cost.
