A ring and hang-up. But I would bet anything that this is the "ACE" electric scam telemarketer. The phone number includes the invalid exchange typical of all their spoofed caller IDs. Blocked.
I filed an FCC 1088 report on this marketer and I advise you to do the same. You can find the online form here:

I had a transcript and audio recording to file with my complaint. Not sure if that will be any help since I'm not sure how you find out who the hell is doing this. But they have called my home once or twice a day for the past few weeks.
I get these calls also, 856-149-8447 and 856-158-9945. My area code is 856, and the next three digits did not look familiar. I haven't answered, and they hang up before my machine picks up. Next time I will answer and complain about this annoyance.
