How to Troubleshoot VoIP Common Issues | Voip Not Working 3

If your VoIP phone is not working, you need to quickly and effectively identify the issue. In most cases, problems such as these have swift and reliable solutions that you can implement, getting your business back on track without delay.

VoIP Phone not working

A VoIP phone is a highly reliable means of conducting crucial communication at your place of business. However, this is not the case if the VoIP is not working. This usually has a very simple solution.

The Solution

One solution is to redeploy your VoIP connection on a Virtual Local Area Network, or VLAN, which may provide a better connection for your VoIP system. You may also want to check if the phone’s SIP ALG feature is turned on — turning this feature off is often a simple way to ensure your VoIP phone is working.

Calls being dropped

If calls are being dropped when you connect with your VoIP phone, this is highly frustrating at best, and unprofessional at worst. It may even result in lost business and revenue. Unfortunately, this is a commonly reported problem with VoIP phones, usually occurring when hardware or software is out of date.

The Solution

You need to check the status of all of the VoIP devices, as well as any other software and hardware you are using in conjunction with your VoIP phone. If you notice any problems, this hardware or software may need to be upgraded. You can also try turning each component off and then on again, one at a time, to see if this fixes the problem.

Poor audio quality

The VoIP phone sends data in sequenced packets, resulting in a smooth transfer of audio. If these packets are being received out of sequence, the audio may become jumbled and generally poor in quality. Muffled or choppy audio can make it difficult to carry out clear and precise conversations.

The Solution

The most common cause is a connectivity or bandwidth problem. You may need to increase your bandwidth so that you can continue to make and receive high-quality calls.

Audio echo

Echoing audio can be severely distracting. This issue can be compounded when it is the call recipient who hears the echo, not the person making the call, as your business clients and partners may be experiencing a problem that you were not even aware of.

The Solution

The echo may simply be caused by your speakerphone function. Turn this off and see if this fixes the problem. Other problems may include a damaged headset, which may need to be upgraded, or you may need to run an internet speed test and check your bandwidth. Damaged Ethernet cables and wall jacks may also result in an echo.

No audio

One common example of VoIP not working is a lack of audio or sound when making or receiving a call. In most cases, this is easily fixed.

The Solution

Disabling the SIP ALG feature may remove this problem. Another option is to check your firewalls — if these are blocking RTP packet transfer, this may be the root cause of the lack of audio.

No ringing or call alert

You need to receive a call alert or hear a ring when you have a call incoming. If this is not the case, you will need to find the cause of the problem.

The Solution

The problem might be linked to registration. Check that your device is registered to your VoIP phone system. If the problem persists, check the phone settings — if you have enabled Do Not Disturb, you may not receive the required call alerts.
