Über Test Number

with 3 comments

This is a short post, but one of the most valuable one in my opinion.

Test numbers!  If you’ve ever done phone deployments you’re aware of the value of a good test number.

For the past two years, I’ve used +1.800.444.444 for my testing.  It reads your caller ID back to you.  Cool, but I want more.  I want features like:

  • Caller ID  playback.  Use this test to trace and label lines in a telephone closet from your butt set in one operation without using your cell phone. The name ID feature helps ID the owner of lines in a crowded NID so you can only install surge suppression on YOUR lines.
  • DTMF Echo.  Have you ever called a voicemail system or bank by phone system and not been able to make menu selections? This test helps confirm the source of common “after connect” DTMF dialing issues on VOIP telephone systems and services.
  • CO Line Toner.  Use this when you have lost your toner, need tone on a live line, or need additional toners to swap circuits.
  • Voice Echo Press.  Test one-way audio effects on VOIP systems.
Well, good news for your Friday…


That’s the ticket!  Give it a shot.  You won’t be disappointed.

  1. Hi buddy, how you doing?

    I tested +1.800.444.444 years ago, but 1.800 is not available outside US. Do you have an international number to make test?

    Best Regards

  2. I called the +1.804-222-1111 and it just read my ANI and played a recorded message, but no other options. But I did find this number online that performed all of the options you were looking for…(and very useful I might add)..only thing is this is not a toll free number~ +1 703-376-ECHO (3246)

  3. 703-376-echo went down for ITSP reasons

    +1 40-VOIP-INFO 408-647-4636 goes to the same place will have more numbers and hopefully some SIP URIs
