10 Most Common VoIP Issues and How to Solve Them

VoIP or Voice over Internet Protocol has many advantages over traditional telephone service, this includes lower costs, flexibility, and portability. Switching to VoIP is normally easy and hassle-free. However, if you have been unfortunate and have encountered issues, no do be dismayed as there is always a solution to a problem. Here are the 10 most common VoIP issues and how to solve them:

1. Low call quality issues

One of the most common VoIP problems is poor call quality. If you're experiencing call quality issues, chances are your network's bandwidth is full, or you have network instability. Audio quality is going to fall back to the most reliable, lower-bandwidth audio formats to not drop the call. If you're experiencing audio quality problems, there are a few things you can do to try to improve your call quality:

VoIPLy Speed Test

-Perform an Internet/VoIP speed test to check your internet and to make sure the issue is not coming from your Internet service provider. A strong, consistent internet is key to good VoIP call quality. If you're on a wireless connection, try moving closer to your router or connecting directly to your modem with an Ethernet cable.

-Disable SIP ALG from your router settings.

-Restart your VoIP devices. If you're still having trouble, reboot your computer, router, and any other devices you're using for your VoIP calls.

-Check for background noise. Background noise can interfere with your VoIP calls, making it difficult to hear the other person on the line. If you're in a noisy environment, try using a headset or moving to a quieter location.

-Update your software and drivers. Outdated software and drivers can cause all sorts of problems, including poor call quality. Be sure to keep your VoIP software and drivers up to date.

2. One-way audio

One-way audio is another common VoIP issue. If you can hear the other person on the line but they can't hear you, there are a few things you can try:

Muted audio

-Check your microphone. Make sure your microphone is plugged in and turned on. If you're using a headset, be sure the mute switch is turned off.

-Check your audio settings. In your VoIP app/software, check to see if your microphone is selected and the volume is turned up.

-Check for background noise. Again, background noise can interfere with your VoIP calls. If you're in a noisy environment, try using a headset or moving to a quieter location.

3. Echoes during VoIP calls

Those that experience echo when making VoIP calls may experience three problems: device lag or latency of headsets. The best way to resolve VoIP problems is to check the phone's components first. Do these websites offer updates? Are the connections correct? Are there any damages? Has anyone ever unplugged or replaced the plug with the same one? Check the call after examining the device. Often the buffers are empty so that the phone can synchronize with the service. If you're using a headset that's different than your current phone, then you're probably just gonna face issues. Bluetooth is a good device, though no perfection. If you can still hear your voice echoed back to you, there are a few things you can try:

background, light, echo

-Check your microphone. Make sure your microphone is not muted and the volume is turned down.

-Check your audio settings. In your VoIP software, check to see if the echo cancellation feature is turned on.

-Check for background noise. Background noise can cause echo, so if you're in a noisy environment, try using a headset or moving to a quieter location.

4. Static

Static is another common issue with VoIP calls. If you're hearing static on your calls, there are a few things you can try:

-Perform an Internet/VoIP speed test to check your internet and to make sure the issue is not coming from your Internet service provider.

It is strange and makes certain things you talk about can be confused and sometimes lost in the conversation.

VoIP enables you to simplify the conversion process into data in the form of smaller chunks of text or video.

There are a few things you can try to reduce jitter:

-Perform an Internet/VoIP speed test to check your internet and to make sure the issue is not coming from your Internet service provider.
