They're measurements of call quality. ASR is the % of terminated calls
that're answered. ACD is average call length.

Short of calling the numbers LNP-type databases would be your only bet I
think, but as Ken points out even they won't be reliable - you may get hits
for invalid numbers if the prefix is valid. And access to them is not free.

"Bad marketing" sounds to be that they are indeed worried about annoying
the customer with robo-calls. They'll be less annoying if they actually
route the call to a sales rep rather than just playing a message and
hanging up, via a queue.
