In the past, plenty of large and medium enterprises spent a lot on IDD call charges. Although they save the cost by using IP phone cards and other ways, it’s difficult to re-dial due to the complicated procedure and the high local call charging. Thus, VoIP Gateway is created to solve the high IDD call charges. This post will introduce what a VoIP gateway is.
VoIP is a device that transfers call traffic into data packets and transmits them via the Internet. In other words, VoIP is similar to the switch of a general computer. At present, VoIP supports features of router and switch. The latter is responsible for exporting network resources to multiple computers, while the former is used to connect a telephone. The VoIP gateway can connect the telephone, fax or PBX in your house or office to Internet devices. That is to say, it can connect the PSTN to IP, achieving voice calling through the Internet.
Two main types of VoIP gateway are the analog and digital gateway.
An analog Voice over Internet Protocol is used to connect your traditional regular telephones to a Voice over IP phone system or to connect your VoIP phone system to the PSTN. Therefore, the analog VoIP gateway includes two types: FXO gateway and FXS gateway.
● FXS Gateway: It connects from your IP phone system to your PSTN.
● FXO Gateway: It connects your fixed telephone or fax to the PBX system, VoIP telephone and analog devices.
It supports E1/T1 (ISDN) and performs as the bridge between traditional PBX and your IP network.
When selecting a VoIP gateway, the number of the devices and FXS or FXO ports should be taken into account. Generally, low-density hardware has fewer ports than high-density models, making them become the best choice for small offices. The analog gateway normally provides 4/8/16/24/48 ports.
As we mentioned above, the VoIP gateway is the bridge between IP and PSTN. According to the position that the voice traffic comes from, the VoIP gateway transforms the voice traffic into the proper form for the targeted networks such as IP or PSTN.
If the voice traffic comes from PSTN, the VoIP gateway will transform the analog voice signals into digital signals. Then, it will compress and resolve the digital signals into a series of data packets that transmit on the IP network by using the signaling protocol.
If the voice traffic comes from an IP network, the VoIP gateway will uncompress data packets into digital signals and then transfer them into analog signals to pass through PSTN.
1. Call load: Make sure the gateway you choose can handle the required VoIP voice call capacity. Take a look at the number of phone calls expected to continue to be made by users during peak periods and then increase that number by another 20% to 25% for future growth in demand.
2. VoIP protocol support: The most common VoIP call signaling protocols are SIP and H.323. Your gateway must support the relevant protocols used by the VoIP system used on your network.
3. Compatibility: You should make sure that the ports on the gateway are compatible with the ports on your PBX device.
4. Cost: The price range of VoIP gateways is wide and varies according to type, brand, performance, and capacity. You should give priority to choosing the best cost-effective VoIP gateway product that meets your budget requirements and usage needs.

A voice-over-internet-protocol (VoIP) gateway is a bridging device that converts call traffic into data packets that can be transmitted over the internet. Public switched telephone network (PSTN) systems are analog and send voice signals along copper wiring, while VoIP systems are digital. Analog and digital gateways are excellent options for businesses switching to business VoIP services but want to maximize the infrastructure they have in place.
In this article, we answer the question, “What is a VoIP gateway?” and explore how it functions, explain the types available, and dive into their benefits for small business communications.
Definition: VoIP gateway devices equip users with the ability to connect to one network to communicate with the devices of another network. VoIP gateway refers to the hardware that changes call traffic from analog to digital signals and vice versa. Without the equipment, signals from one system would be incompatible with the other, and signals would be stuck trying to switch from one to the other.
In this section, we’ll break down what is a VoIP gateway and how it works. Simply put, it’s a network’s entry and exit point where routed data must pass through to be converted from one protocol or format to another. Standard gateways interface with both IP networks and PSTN telephone services.
To connect analog and digital networks, gateway devices use a phone jack, or what’s also known as a register jack-11 (RJ11). The register RJ-11 plugs into your gateway’s foreign exchange office (FXO) or foreign exchange subscriber (FXS). The gateway typically contains an analog telephone adapter (ATA), which converts the signal from digital to analog and vice versa. The gateway may also have an Ethernet port to connect to your internet service.

Once the gateway device is connected, it enables existing hardware, like desk phones and fax machines, to communicate with the VoIP or PSTN service. This helps your team use non-digital hardware and connect them to your internet-based phone system. Your team can answer different network phone lines without switching devices.
Depending on the equipment and hardware you’re using, VoIP or FXS gateways work with varying types of networks, including cloud and on-premise public branch exchange (PBX), local area network (LAN), time-division multiplexing (TDM), and global system for mobiles (GSM).
There are two ways in which data is converted to be transmitted over the internet:
Gateways are great because they allow you to capitalize on two systems; however, there are instances when VoIP systems fail. These gateways have “fallback” modes that enable you to switch to your PSTN when the internet is down, ensuring continued communications. This hybrid approach enables small businesses on a tight budget to take advantage of VoIP benefits while utilizing current technologies that your team finds familiar and reliable.

Voice-over-IP gateways are available in several versions and have varying capabilities. These devices may have one or both PSTN and IP-based connections. Analog devices connect your legacy telephones to a VoIP phone system or connect your VoIP system to the PSTN. Here are the types of analog gateways:
FXO and FXS are analog gateways typically available in two to 24-port configurations. Digital gateways bridge traditional PBX systems and an IP network.
When selecting your voice-over-IP gateway, consider the number of devices and the subsequent FXS or FXO ports you need. When choosing between low-density and high-density models, teams in small offices are better with low-density devices because these generally have fewer ports and are more affordable.
Other points of consideration include your call load, compatibility, and overall cost. Ensure your gateway can handle your call capacity, especially during peak season. Check if the gateway ports are compatible with your PBX device’s ports, ensuring your system will work well. Lastly, the prices for gateways vary depending on brand, performance, and capacity. Assess your current equipment and budget, then choose the most cost-effective option.
Now that the definition has been discussed, it’s time to look into the advantages businesses derive from using VoIP gateways. IP gateways have several benefits, particularly for small to medium-sized businesses connecting or transitioning from one type of business phone system to another. Take a look at the benefits of using gateway devices for your communication stack:
Considering the investment businesses put into setting up their legacy, on-premise systems, the decision to replace phone systems isn’t a decision most small teams take lightly. VoIP and FXO gateways unify telephony platforms, enabling you to use your existing analog systems while deploying cloud communication features. This reduces the upfront cost related to upgrading phone systems.
Gateways are an excellent help for teams looking to allocate their time and migrate phone systems in phases. Gateway devices manage costs by allowing you to transition over an extended period.
VoIP is typically cheaper than landlines because it uses an existing internet connection to place calls. Recent industry reports indicate that businesses have shown cost savings, increased productivity, and strengthened security since migrating to the cloud. VoIP phone systems don’t require the same hardware investment and infrastructure maintenance.
