Testing telephone and fax numbers

#telephony

If you're setting up a phone or faxing system, you're going to need to make test calls and faxes to verify that things are working.

I wanted to write down the test numbers that I've used that are working as of 2021-Nov-12.

Phone numbers with voice utilities

These numbers can be called and have tools that can test functionality or connection issues with your phone.
