Setting up VoIP router

Which Type of VoIP Router Do You Need?

There are three types of VoIP routers: single-, dual-, and tri-band. Here are the differences:


Single-Band VoIP Routers

Sing-band routers operate on one frequency: 2.4 GHz. Most of the older single-band routers use the 2003-802.11g frequency, which caps data speeds at a low 54 Mbps. Other single-band VoIP routers use the 802.11n, or Wireless-N, that operate on a 2.4 GHz band and offer speeds up to 800 Mbps. Due to limitations in internet services, most users won’t see those speeds.


Dual-Band VoIP Routers

A dual-band router supports both 2.4 GHz and 5 GHz frequency bands. With the 5 GHz band, you can expect a faster, more reliable connection, which is beneficial for offices where many users are using the connection at the same time. 

Dual-bands are without a doubt a better option than single-band for business use. Some dual-band VoIP routers also offer MU-MIMO support, which improves the way Wi-Fi interacts with different devices. Routers without this functionality can only interchange with one device at a time.


Tri-Band VoIP Routers

A tri-band router has the capability of Gigabit speeds, and on the 5 GHz band, they can get upwards of 4,000 Gbps. Tri-band refers to the fact that these routers operate with one 2.4 GHz band and two 5 GHz bands. 

By using automated features, these routers direct other devices to the 5 GHz band and reduce signal interference much better than dual-band routers. Tri-band VoIP routers are the best choice for offices that use various 5 GHz connected devices.


Mesh Networks

A mesh network connects routers together to supply an internet connection over a large area. They consist of various routers that each provide coverage while communicating with other nearby interlocked routers. 

Mesh networks are ideal for large buildings, as they can deliver the connection anywhere you need, like throughout an entire office building spanning multiple floors.


The 5 Features You Should Look For in a VoIP Router

Finding a VoIP router that has all of the important features can be challenging, especially if you’ve never purchased one before. When shopping around, you’ll find that there are hundreds of varieties of routers to choose from. On top of that, some of the technical terms can be confusing. We’ll break it all down for you.


#1: Quality of Service (QoS)

Quality of service describes the overall performance of a service—in this case, however, it’s a feature of routers and switches. They prioritize traffic in a way that allows the most important data to pass through it first, improving the performance and efficiency of the network.

QoS is important for VoIP devices and in LANs that see high volumes of traffic. It’s particularly useful for transporting traffic with special requirements.


#2: Virtual LANs (VLANs)

Virtual LANs address security, scalability, and network management by providing network segmentation. VoIP routers between VLANs mitigate congestion, filter traffic, enhance the network’s security, and perform address summarization. 

VLANs communicate with each other to route traffic between them in the most efficient way possible.


#3: Dual- & Tri-Band Frequencies

Dual-band frequencies operate on one 2.4 GHz band and one 5 GHz band. Speeds can be up to 450 Mbps and 1,300 Mbps, respectively.

Tri-band frequencies operate on one 2.4 GHz band and two 5 GHz bands. Tri-band routers reduce more signal interference and result in clearer call quality with VoIP services than dual-band routers.


#4: MU-MIMO & 8.211ac

MU-MIMO—multi-user, multiple-input, multiple-output—is a newer feature of VoIP routers. Basically, it allows multiple users to share a connection without experiencing reduced speeds.

8.211ac is a LAN technology that increases overall performance and provides the fastest wireless speeds.


#5: SIP Support & H.323

SIP sets up a session across two points and is an important part of any internet architecture. While its initial focus was on voice communications, SIP has expanded to include features like application sharing, video calls, instant messaging, and various other forms of communications.

H.323 is a standard developed to support media communications over a network. While it initially focused on supporting video conferencing, it now also includes audio call functions.


So, What’s the Best VoIP Router in 2021?

While there isn’t one “best” VoIP router for every business, if we had to choose the top one from this list, it would have to be the SonicWall TZ series. It offers the best QoS capabilities, is easy to set up, and works exceptionally well for almost any application. 

Of course, it might not be ideal for every setup since every office will have different requirements and network layouts.

To get the best communication quality for your business, a fast and reliable VoIP router is essential. For those that handle sensitive information, you’ll want to ensure that you purchase a router with reliable security features, like the FortiGate 42E, Sophos UTM, or WatchGuard FireBox T35.
