Test Phone Numbers

If you need to test communications equipment like a new PBX, test numbers come in quite useful.

The following are a list of test phone numbers that I use.

The Test Line

The Test Line is a service that I provide that provides a suite of tests including:

  • Caller ID read back
  • DTMF test
  • Echo test
  • Milliwatt Test Tone ;and
  • Music on Hold

You can reach the test line on the following numbers:

  • Australia: 02 9192 0995 or +61 2 9192 0995
  • New Zealand: 09 887 6986 or +64 9 887 6986
  • North America: (628) 246 2222 or +1 628 246 2222

To prevent abuse you must present valid caller ID from one of the countries above.
