I just received a call from this number. When the answering machine picked up, the caller hung up. My caller ID says the number belongs to ESHD. My guess is this is another telemarketer call.

i picked up after two rings but no one on the other end.  Most likely a robocall

I get these calls almost daily on my work cellphone.  Caller usually hangs up upon answer.  Callback leads to message from Home Energy Solutions and option to add your number to their do not call list.  Do not enter your number, it will lead to more calls.  Home Energy Solutions website insists they are not the originator of these robocalls and urges to file complaint with FTC.  Most likely scam.
