How to Troubleshoot VoIP Issues

Troubleshoot your VoIP service before calling your service provider to help rule out common issues.

VoIP, or Voice over Internet Protocol, delivers digital telephone service via a high-speed Internet connection. If problems arise with your VoIP service, locating the source of the problem can be challenging. There are several items you can try before calling your service provider for support, which will help to rule out some of the most common issues.

Instructions

1. Verify all of the connections between the modem, VoIP adapter and telephone are securely attached.

2. Test your Internet connection's ping by using a ping test site (see Resources). Ensure that the latency of your connection is in the acceptable range of 100ms or less.

3. Test the speed of your Internet connection by visiting a speed test site (see Resources). For optimal VoIP performance, your connection should provide a minimum speed of 1 Mbps.

4. Reset your modem and VoIP adapter by powering them off for 15 seconds. Allow both items to fully power cycle before attempting to test the status of your VoIP service.

Tips & Warnings

• If you receive unsatisfactory results from your ping test or speed test, contact your Internet service provider for support.
