How to Deal With Jitter for VoIP


Jitter is one the three most common VoIP problems. When jitter occurs, it is difficult to understand what the other person is saying because the packet is delivered in the wrong order and, as a result, the words and syllables are messed up.

Things You'll Need

  • Cat6 Ethernet cable
  • Telephone adapter (if applicable)
  • Know how computer usage effects jitter. Large computer applications running while you are on the phone at the same time causes jitter. Close the programs to allow more bandwidth to be dedicated to your VoIP line to reduce jitter.

  • Adjust your jitter buffer. Contact your VoIP service provider to adjust this buffer, which allows you to set lower time limits regarding acceptable jitter.

  • Replace Cat 5 or Cat5e Ethernet cables with Cat6. Cat6 Ethernet cables transfer data faster than Cat5 or Cat5e cables. This higher rate of data transfer will help deal with jitter for VoIP lines.

  • Shorten your Ethernet cable line. Ethernet lines that are too long have been known to cause an increase in jitter. With shorter lines, the information travels more quickly, reducing the amount of jitter you will experience.

  • Get a different phone adapter. Jitter can be caused by poor quality phone adapters. Replacing yours could reduce or eliminate jitter.

Tips & Warnings

  • Always call your VoIP service provider when attempting to fix phone service problems. Don't take the risk of making your problem worse because you don't know what you're doing.
