Telephone system test numbers

There's a lot of old test numbers out there for the phone system - number readbacks, echo testing, tone testing, information lines, etc. They're not used much anymore, but for those who still work with switchgear they can be useful. They're also useful to forward spammy callers to, because the numbers are automated and will just take calls.

Disclaimer: I have no idea who runs this stuff anymore.

Some of the ones I still know about:

248-434-5508 Voice / Music Line Test 800-444-4444 Number Readback <--- This one has a menu tree for some reason 909-390-0003 Echo Test 503-697-1000 Milliwatt Tone Test

Some VOIP providers will let you dial 933 to test 911 service. It'll read back your number and location assuming it's provisioned correctly.

Yeah, a lot of providers have their own numbers you can call. These should work anywhere you can make a phone call.

What's left of MCI was acquired by Verizon in 2006 - this service has to be at least 20 years old...
