Many small- or medium-sized businesses could benefit from switching to Voice over Internet Protocol (VoIP) phone systems. But you can't take advantage of the cost savings or improved efficiency without understanding how to use this technology properly and deal with the occasional issue. Here are some of the most common VoIP issues and how to troubleshoot them.
Jittery or crackly audio on VoIP calls may be caused by electromagnetic interference, damaged equipment, or insufficient bandwidth. Here are some solutions to fix this.
- Check VoIP phones and cables for any signs of damage.
- Keep your VoIP equipment at a safe distance from each other to prevent electromagnetic interference.
- Conduct a bandwidth speed test to ensure optimal network performance.
Do your phone calls suddenly disconnect after 11 minutes? This could be due to outdated firmware or a user datagram protocol (UDP) timeout. Luckily, there are ways to solve these problems.
- Ensure that your phones have the latest firmware updates.
- Adjust your router settings to prevent UDP timeouts, or switch to Transmission Control Protocol.
Echoes and audio delays
Experiencing echoes or audio delays during phone calls or video conferences is a widespread problem that can be caused by network latency, headset lag, device issues, or other factors. Don't fret, the following tips can help.
- Ensure that your device is correctly plugged in and updated with the latest software.
- Unplug your phone and reconnect it again. This will clear any buffers and allow your phone to re-sync with your internet connection.
- Consider switching to a corded headset instead of a Bluetooth one. Bluetooth headsets tend to lag, which can result in audio delays.
- Ensure that you have enough internet bandwidth for smooth communication.
Having trouble hearing the person on the other end of your phone calls? Your firewall may be blocking the transmission of Real-Time Transport Protocol packets. To solve this, you'll need to open up some ports on your firewall.
Unable to make calls
If you can't make calls from your VoIP phone or see a big X on the screen, it's possible that you're using two routers and they're dropping important data packets. This is typically caused by your network setup. To resolve the issue, disable Session Initiation Protocol Application-Level Gateway on your router and confirm that you're not using two routers. You could also connect your VoIP phones to a virtual local area network for a quick fix.
Calls sent to voicemail
If your VoIP phones aren't ringing, it may be because calls are being sent to voicemail. Check that your phone isn't in Do Not Disturb mode and confirm that your VoIP phones are still registered with your provider.
