VoIP System Problems, Their Solutions & Tips To Fix Them

VoIP phones are a fantastic option to landline systems. Why? Because they offer better call quality, dependability, and unification, all in a very cost-effective package compared to traditional phone lines or PBX. some of the best IP Phones for Business that actually suit your business needs and goals will boost overall performance.

But, even though it is perfect in many ways possible, there is a chance of disruption. Like if you have been using a VoIP phone system and a call is disrupted by choppy audio, dropped connections, or robotic voices, well, you know the real frustration. 

Statistically speaking, 83% of companies lose their customers, miss a major deadline, or terminate an employee due to a communication issue. No one wants these types of problems with VoIP phone systems. Well, these types of problems with VoIP systems can be easily resolved with the correct knowledge and technology.

In this article, we will guide you through the most common VoIP system problems and their solutions, troubleshoot VoIP network issues, and provide tips to fix recurring issues.

You’ll save your IT staff’s time and get your business VoIP phone system into the best shape in no time.

Common VoIP System Problems

Voice Over Internet Protocol (VoIP) systems send calls over the internet and rely on your local network and bandwidth, so if VoIP connection issues occur, then there will be a disruption. A weak link in the chain can negatively impact overall voice quality.

Below are some common VoIP issues and tips for troubleshooting VoIP network issues:

1. Poor Call Quality or Retarded Audio:

Since VoIP calls are transmitted in real time as data packets, any disruption in voice packets received by the destination IP address will be heard as choppy, distorted, or delayed audio on calls. It is certainly not a part of voip phone system problems.

Solution:

If you are experiencing call quality issues, look for these:

1. Poor Bandwidth.
2. Network Jitter.
3. Packet Loss.
4. Improper quality of service Setting.

How To Fix Choppy Voice:

Run speed tests and make sure you meet the required bandwidth from your VoIP provider. Afterwards, test your network for issues like high latency jitter or packet loss during calls and troubleshoot accordingly. This may involve router firmware upgrades or contacting your internet service provider (ISP). 

Some other tips for troubleshooting voip network issues are:

1. Enable Quality of Service (quality of service) on your router so that VoIP traffic gets priority.
2. Use a wired Ethernet connection rather than Wi-Fi whenever possible.
3. Disable extra network hardware like VPNs, guest networks, and high-capacity applications like YouTube, Netflix, etc.
4. Place your phone on a Virtual Local Area Network (VLAN) to separate it from other network traffic. 

2. Dropped calls

If a VoIP call is disconnecting randomly, then the first step is to contact your phone provider. Other than that second issue, a UDP timeout is the amount of time a UDP route stays open on a firewall or router. 

VoIP firewall issues can be easily resolved. UDP network traffic is faster because it lacks the error-checking capabilities TCP offers. As a result, it is exposed to firewalls, closing the connection and ending the call unexpectedly.

How to fix it:

Here are some steps to address VoIP firewall issues:

1. Reset VoIP phones to re-register them with the VoIP server fresh.
2. Check that Firewalls, VPNs, or routers are not blocking access to critical VoIP ports and protocols.
3. Adjust router settings to allow longer UDP timeouts.
4. Monitor your network quality during calls using built-in phone graphs and logs.
5. Use Power over Ethernet (PoE) switches to hardwire IP phones. 

3. Voice Echoes

Hearing your own voice is very annoying, especially during important calls. Three potential problems cause voice echoes: headset lag, network latency, or audio configuration issues.

How To Fix It:

Here are some tips for this type of VoIP System problems.

1. Use a proper VoIP headset or mic setup.
2. Fix audio configuration issues.
3. Enable quality of service settings and VLAN assignments to prioritise voice traffic on your network so latency can be minimised.

4. Calls without any sound

Voice dependability hangs on the intermediate network, firewalls, and audio software stack working correctly. Improperly configured VoIP phones, wrong loose wiring and connectors, clashing codecs, heavy network congestion, and quality of service glitches can cause excessive latency, jitter, and packet loss, which can stop real-time audio despite calls connecting fine at the VoIP protocol layers. 

How To Fix Audio Issues:

Fully plug the headset connection into the VoIP phone ports. Check that volume levels on VoIP phones are turned up. Check phone configurations to select the correct audio input/output settings. Devices may use the wrong inputs, like Bluetooth, when wired headsets are expected.

Toggle between codecs on the VoIP phones to rule out codec incompatibility issues. Also, reboot the phone to reinitialise codec handshaking after switching. Also, check and update the VoIP phone firmware.

5. Unable To Make Calls

If a big “X” appears on the screen, or you are unable to make an outbound call, chances are that two routers are dropping packets of data. These VoIP System problems have nothing to do with your router connection or network layout.

Certain protocols are processed by the Application Layer Gateway (ALG) and rewritten for smooth flow through a firewall or (Network Address Translation), still, it causes several VoIP phone problems.

How to Fix these VoIP phone problems:

To solve the VoIP System problems, disable SIP ALG and avoid having double NAT or two routers that prevent the flow of packets. Placing your VoIPphones on a VLAN can also help.

Troubleshooting VoIP Network Issues

VoIP issues often feel challenging to find and resolve. Here we are going to provide you with some tips to fix it easily:

1. Check internet speed and stability.
2. Conduct test calls.
3. Check VoIP connections:
   1. Segment VoIP phones on your network into their own VLAN for higher performance.
   2. Use CAT5e/CAT6 cabling with the same media type (10BASE-T vs. 1000BASE-T); poor wiring causes latency.
   3. Ping should be less than 80 millisecs and jitter should be less than 30 millisecs.
   4. Prioritise SIP traffic with quality of service. Confirm that your router and switches prioritise VoIP traffic and devices.

4. Test the quality of service Settings to check if they’re causing it.

5. Update Firmware/Software.

6. Use a VPN.

7. Contact Your VoIP Provider.
