What Is Bandwidth?

The time it takes for data transfer through your network is called “bandwidth.” Liken it to traffic on a motorway. If the vehicles represent data, then your internet bandwidth is represented by the road. At any given time, only a small number of cars can fit on the highway.

Cars can travel freely during times of low traffic. You are stuck in a traffic gridlock at the busiest part of an early morning commute. The same principles apply to your capacity. A particular amount of data can be handled by your internet connection. Your connection becomes congested during excessive data use, which lowers the quality of your calls.

Data is used in all online activities, including web conferencing and emailing. Data packets are transferred between your devices and your network. The size of a package might range from 1,000 to 1,500 bytes. The time it takes to send or receive data is measured in terms of bandwidth.

  • Three standard measures are used to determine VoIP bandwidth needs:
  • Gigabits per second (Gbps) and megabits per second (Mbps) (Gbps)
  • Terabits/second (Tbps)

You might hear “bytes per second” from your internet service provider (ISP). Eight bits make up one byte. For example, internet speeds are often expressed in terms of megabytes per second (MB or Mbps) or kilobytes per second (kbps) (KB or Kbps).

What Is Internet Speed?

Internet speed and bandwidth are different things. Your data’s transport rate across the internet is called speed. You might be able to satisfy VoIP bandwidth needs. But a modest data transfer rate is still conceivable. Your call quality is impacted by internet speed. Possible causes of slow internet include:

  • The point of connection: Wi-Fi may result in slower speeds, while wired connections increase rates.
  • Older wiring or equipment: Out-of-date equipment, such as your router, may slow down your internet speed.
  • Type of connection: DSL internet is slower than cable internet. The quickest internet is fiber optic.
  • Traffic: Internet speed is reduced during busy periods.

How To Test Your Internet And Voip Speed?

Your VoIP bandwidth can be easily tested with an online bandwidth speed test. There are numerous tools available online. This one-click internet speed test is offered by 8×8. Find out how many phones your internet bandwidth can support after a trial. Apply a simple math formula to this (more on this below).

What A Test Of Internet Speed Reveals?

Your upload and download rates and jitter and latency are displayed via a bandwidth test. Let’s go over these terms’ definitions one by one.

Download Speed

ISPs use this number to describe their services. You can purchase either a 10 Mbps or a 100 Mbps plan. This figure represents the speed at which you can download something from the internet. For instance, your download rate when streaming a video influences how quickly you see the content.

Upload Speed

This figure can be the same as your upload speed. However, it’s typically lower. Your upload speed is how quickly you can transfer a data packet per second. Therefore, upload speed impacts how fast your video uploads to the internet.


The unit of measurement for the delay in milliseconds (ms). This phrase describes how long it takes for the info to get around. It measures how long it takes between delivering data and receiving it back in milliseconds.


There are inevitable delays for all sent data. This is because each file you transmit over the internet leaves in a separate packet. It consists of five different cars rather than a bus full of students. High jitter rates on internet connections cause some information packets not to be delivered fully at once. If you use VoIP phone services, this can be a problem. However, if your jitter is under 30 ms, you won’t experience any significant issues.


The time it takes for the IP address to reply to your initial data packet is measured in pings your speed increases as the number decrease.

Factors Impacting VoIP Service Consistency

Go over each of these concerns if you’re experiencing call quality issues. Your VoIP service provider could offer further assistance to guarantee clear calls.

  • Provider of VoIP services: A trustworthy provider reports minimal downtime. They provide hardware and software updates. Additionally, your VoIP service must offer continuing assistance.
  • Equipment: Calls with poor call quality are influenced by your Wi-Fi signal. When the Wi-Fi signal is weak, use a Wi-Fi booster. Additionally, it would help if you looked at the bandwidth needs of your softphone. After years of use, all equipment, including routers, modems, and headsets, has to be replaced.
  • Internet connection: Your VoIP service consistency is impacted by your download and upload speeds. A shared ISP also increases the number of concurrent users of the relationship. Discuss service improvements with your internet provider.
  • Software: Updating your gadgets’ software could change how they connect to the internet. If you are encountering a slow connection, look for updates. Caller connection: The issue might not be with you. The call quality will suffer if you contact someone with a bad link or slow internet. User blunder: It’s crucial to train personnel to set up and use new equipment when implementing a new VoIP system. For instance, people should refrain from downloading huge files when on a video call.
  • Distance to server: Most small firms use the servers provided by their ISP. Call quality may be reduced by servers placing a space from your company address.

How To Improve Consistency Of Service?

Review your internet service and software to ensure it meets VoIP bandwidth requirements. By using the best VoIP provider, updating software and equipment, and utilizing fast internet services, you may increase VoIP service consistency.

Your internet connection comes first. Learn about upgrading choices from your ISP. Your needed number of office devices must be compatible with your internet speed. If necessary, talk about your options for additional bandwidth assistance.

Next, register with a respected vendor of a cloud-based phone system. An excellent VoIP service interacts with your plans and allows you access to high-quality communications. Additionally, you’ll receive assistance with training or quality issues. Adapt your hardware and software. Consider updating your softphone, modem, or router if you have poor call quality. Doing this gives you access to cutting-edge technologies and superior call quality.

How To Get Reliable VoIP Service?

  • Uptime: VoIP uptime is an estimation of how much of the time the system is functional. This sum is computed over 12 months. Service interruptions or disruptions come from lower uptimes.
  • Uptime warranty: Some VoIP companies (SLA) provide a service level agreement. It establishes requirements for uptime and call quality.
  • Redundant service: In business communications, call continuity is crucial. Having backup systems in place in emergencies is known as redundant service. These systems minimize VoIP outages.

Testing Your New VoIP Phones

Test new headsets, softphones, and other VoIP equipment when you get them. Connect the VoIP phone to the router. After that, insert the power cord into the outlet. Users of mobile devices should evaluate the connections in diverse working spaces. You can start using your phones after plugging them in. However, making a test call to a coworker over the phone is brilliant.

Ensure that your personnel is familiar with modern technology, such as softphones. You’ve updated any software or applications on your devices.

Frequently Asked Questions

Is bandwidth critical in VoIP?

Additionally, call centers can utilize VoIP technology with just an internet connection because it is cloud-compatible. However, since voice data is a sort of data that is significantly bulkier than typical text, bandwidth needs are crucial for voice communication using VoIP technology.

What is the typical bandwidth for a telephone voice channel?

Analog telephones have a bandwidth of 3.1 kilohertz, which is high enough to transmit intelligible speech. This bandwidth is between the lower limit frequency of 300 Hz and the upper limit frequency of 3,400 hertz.

What is the bandwidth required for a voice signal?

Voice signals typically have a rate of 4 Kbps to 64 Kbps, depending on how compressed and low-quality they are. Audio signals can be sent from 8 Kbps to around 1.3 Mbps for CD quality.

Which is better, SIP or VoIP?

SIP permits SIP trunking, a crucial element of the VoIP system for any expanding company. Similar to VoIP, a SIP trunk functions as a virtual phone line and uses packet switching to connect calls. SIP trunking allows voice, video, message, and fax, whereas VoIP alone supports voice.
