Same here... I received a call from this number at 4:29 CST today, and it went immediately into the recording of a conference call in progress. I hung up without pressing any keys. I suspect that if one has ever been involved with a network marketing group of any kind & at any time, that the up-line managers can access your information and take it with them from company to company as they move around. I made the mistake of joining one of these many moons ago, and I have received this type of call from time to time, and there's seemingly no way to put an end to them.
I just got tagged by this call on my cell phone and didn't answer it so it has nothing to do if you have Vonage or not, your number can be acquired from a variety of different sources.
Just called. Same thing about the conference call. If you listen long enough, it said press "9" to place on their DNC list. So I did. Considering I am already on the Federal DNC list, I shouldn't have to do this.
