Debugging and Troubleshooting VoIP

Introduction

Debugging and Troubleshooting VoIP

Implementing a Unified Communication strategy like VoIP continues to be an increasing trend. The underlying technology supporting VoIP is network dependant. Voice Quality problems are often related to the network. As Voice is a critical application being able to troubleshoot these problems effectively and in a timely manner is critical to your continuing operations.

VoIP is extremely sensitive to delay and packet loss compared to other network applications such as web and e-mail services. This presents a real challenge and means we need to look at network statistics from a different perspective.

Network-Related VoIP Symptoms

Examples that you might be asked to troubleshoot include:

  • Network Delay can cause a delay between the time you talk and when the other side hears you. You may start talking not realizing that the other party has already started talking
  • Packet Loss can cause "holes" in the conversation where the other side is talking and you don't hear anything.
  • Jitter can cause muffled or garbled words, or high distortion
  • You can hear echo when you talk. This can be exacerbated by network problems, but a constant echo is usually not caused by network problems.
  • You are not able to connect.
