The Niles SAS-1 + APC-2 combo would have done this. I say "would" because the SAS-1 is now discontinued, though you may find it still on eBay or Amazon.

RDL's (www.rdlnet.com) ST-ACR2 should work for the audio sensing portion. If the APC-2 is also unavailable, Xantech AC1 would work in place of APC-2.
