what does my network need to support voip
Businesses who use VoIP, or are looking to switch to VoIP, oftentimes wonder how much bandwidth is needed to support their VoIP phone system. VoIP phone systems depend on your Net network to road calls. And so there are things you lot need to know about setting up your Internet network to ensure you have the best phone call quality possible. The showtime footstep is agreement how VoIP uses bandwidth to function, and how much bandwidth you will need for your system.
How does VoIP use bandwidth?
To summarize, VoIP uses your Net network's bandwidth to operate. Bandwidth determines how quickly y'all tin transport data via the Net during a given catamenia of time.
This is where VoIP comes in. VoIP systems transform sound (voice) data into codecs by compressing and decompressing it. Then, it sends those codecs across the Internet to reach the other phone line. In order to practice this, it needs a minimum amount of bandwidth from your network. To do it quickly and efficiently, it often needs more bandwidth than the minimum required.
How much bandwidth do I need for VoIP?
The amount of bandwidth needed for VoIP depends on how many phone lines y'all have running at once. For example, if you lot are a small company with simply 5 users who just sometimes apply your phone lines, your bandwidth needs will exist much different than a medium visitor with 20 users all using their phone lines regularly.
Take a wait at these bandwidth requirements and recommendations:
| Number of Concurrent Calls | Minimum Bandwidth Required | Platonic Bandwidth |
| 1 | 100 Kbps | three Mbps |
| three | 300 Kbps | three Mbps |
| 5 | 500 Kbps | v Mbps |
| ten | 1 Mbps | 5-10 Mbps |
| 15 | 1.v Mbps | x+ Mbps |
| 20 | ii Mbps | 10+ Mbps |
As you can come across, nigh telephone lines require 100 kilobits per second (Kbps) to back up an sound phone telephone call. That ways if 3 employees are using their phone lines at the aforementioned time, your network will require 300 Kbps to support all 3 calls. To calculate the minimum bandwidth you need, employ this unproblematic formula:
It's also of import to keep in listen that these numbers are minimum requirements to support phone calls. It does not hateful those calls will exist of the highest possible quality. If you are using a unified communication arrangement, the amount of bandwidth needed for VoIP will be more the minimum listed here. To go the best voice quality results and best VoIP experience overall, we recommend choosing the "ideal" bandwidth listed above.
How to Figure out your Bandwidth
Figuring out exactly how much bandwidth your network allows is the beginning step to optimizing your VoIP system. Your bandwidth depends on a few things:
- Router or modem
- Installed web browsers
- Internet settings and configurations
- Internet Service Provider (Internet access provider)
The type of service your ISP provides y'all with is the number 1 cistron in determining bandwidth capabilities. The best way to determine your bandwidth is to just call your provider and ask about your bandwidth. They will probable tell you lot that your bandwidth supports "up to" a sure corporeality, such as "up to 50 Mbps" or "up to 150 Mbps."
You tin can likewise examination your bandwidth or "Internet speed" by doing a uncomplicated test using online resources such as speedtest.net. This will tell you your upload and download speeds, every bit well as your functional bandwidth.
Go on in heed that bandwidth usage and Internet speed also depend on how many devices are also using the Cyberspace at the same fourth dimension. In other words, if you have many devices connected to the Internet at once, your bandwidth will be more than used up and each device may run slower.
How to Troubleshoot VoIP Bandwidth Issues
Are you experiencing VoIP lagging (aka voice latency), which is causing you to question your bandwidth? In that location are several things you lot can do.
i. Wait into latency
Keep in listen that while some voice latency is normal for VoIP systems, as well much will crusade issues for your business communications. The "acceptable" or normal corporeality of latency for VoIP systems is betwixt 150-300 milliseconds. Whatsoever more than than this window is considered "too much." Learn more than about VoIP latency and how to troubleshoot it.
two. Suit QoS Settings
| UDP/5060 – Priority: Loftier |
| UDP/6060 – Priority: High |
| UDP/16384 to 32768 – Priority: High |
Internet-based devices take built-in Quality of Service (QoS) settings via their routers. This allows y'all to "prioritize" bandwidth for some devices over others, depending on what y'all use on a regular basis. If you are using your telephone organisation regularly, you want to adapt these settings to requite sufficient bandwidth to VoIP. We recommend adjusting QoS settings to the following to all-time back up VoIP:
3. Determine your type of codecs
Every bit we mentioned, VoIP compresses and decompresses information using tools called codecs. There are a few unlike types of codecs, and each requires dissimilar amounts of bandwidth to operate. It's possible your VoIP provider uses codecs that require a high amount of bandwidth. You can always talk to your provider virtually what types of codecs they use. If this blazon is non optimal for your business organisation or takes up too much bandwidth, you can consider switching to a different provider.
4. Upgrade your bandwidth
Although it will cost a bit more, the single best way to become the bandwidth needed for VoIP is to invest in more bandwidth. You should consider this a worthwhile investment, since your Internet helps your business operate on a mean solar day-to-day basis. Upgrading your bandwidth volition improve your communications across the board, making all your Internet-based devices run quicker and more smoothly.
