A hell of a lot of toll free numbers ending in 000 & 0000 is a medical alert device/Americas hottest talk line (a/h) number
It’s quite common for numbers ending in 00 to also be them
I just made up a few numbers at random.
If you dial too many of these medical alert device numbers from the same caller ID, you’ll start to get it diverting to this
But this is the same number dialed when the caller ID is changed to a fresh one
