Would it be possible to add the identity to this warning?

That is handled by Asterisk so you would need to open a request with them.

I would also like to have failed calls recorded in the CDR in order to increase their visibility. It wouldn’t hurt to have a failed call or significate error counter on the Dashboard as well (or some such).

Is the CDR supported under FreePBX or Asterisk?
