Recently I had to write a script that would connect to our VOIP provider and send a fax via their web form. The idea was to elminate the additional steps of logging into their system, navigating to the "Send a Fax" section then filling out the form and clicking send. However once I had a script written I needed to test it. Unfortunately nobody these days has a fax machine. Thankfully I found a website that helped me out.
The website FaxToy.net allows you to send a fax to their number, then within minutes it will appear on the homepage. Just send a fax to either 888-877-1655 ( toll free), or 503-200-1300. Then wait a few minutes and it will appear in classic 1980s greyscale. You can click it for a enlarged version of its pixelated glory.
Great and Free way to test to make sure your fax machine is working
