ringing works fine, but then the hid report stops updating with on-hook/off-hook and dialed number. (volume warning for video: loud tones)

got it working with both discord & google voice

finally got caller id working after many hours. normally it's sent between the first and second ring, but I'm sending it before the first ring because these phones wait for the caller id data.

I found an old magicjack adapter laying around and decided to poke around at it. It uses HID and it's actually pretty easy to read data from the phone / make the phone ring. would be cool to use this for other voip services.
