Incoming line is digital (PRI, R2) or Analog (FXO)?

Strange problem I'm troubleshooting.

External caller calls into a specific number, about 1 sec after they call they get a fast busy.

Internal user hears the phone ring, when they pick it up there is no longer an active call on the phone.

According to CAR there is never a "Connect" timestamp, I see the call start and call end though.  It's usually a second or less.

Only seems to happen with this extension, and only with certain incoming callers.  Other callers to that same number have no problem getting through.

I'm at a loss as to what could be causing this...Faulty phone hanging up on them?  Problem on the caller's side?  PRI glitches?

Any way I can find more info, maybe even a reason the call is being disconnected?
