One ring - hung up. Much like other "robo" calls: they call a bank of number, when one answers, they give their pitch but you may get called back. I've been told NOT to use the DNC option if they offer it because (1) the communication may mean you're "doing business" and they can call you often, (2) it somehow is an authorization for an overseas call to be placed on your phone account. Don't be curious - if you don't know the number, don't call. If it's important, they'll leave a message.
Just got a call from this number, rang twice then hung up. Just googled the number and ended up here, looks like they've been busy the last 2 days. Last week got a call my Chase MasterCard/Debit card was locked, only problem don't have one, so glad I'm on the Do Not Call list.
I just got a call from this number, it rang twice then stopped. I didn't recognize the number so I didn't bother even answering it, and the caller ID said Aud Plus Video.
I get so tired of these darn scam/robo calls its pathetic.
