If that's the approach you take, then you're going to have a very crowded contact list very quickly.
Telemarketing calls to cell phones are illegal outright. We're a small business that uses telemarketing (please put the pitchforks down), and I myself have dug through alot of the rules and regulations regarding who we can call.
Cellphones are a sin. Even if you're a business, any telemarketing call that costs the person called money is illegal. It's just as bad as getting a telemarketer calling you collect. DNC has no jurisdiction on cellphones, because it's just outright illegal to telemarket to them.
If I were you, I'd go to the FTC about this. However, if your cell phone is receiving forwarded calls from a landline, that could hurt your case.
I received a call on my work phone, no answer when I picked up. I have caller ID, called the number to see who it was (I have been getting a multitude of calls regarding setting up credit card systems for my business which I do not need). The number had me choose 1 if I wanted my number to not be called again, and I had to choose 1 again to be put on their no call list.
I had the same experience as "Mom" in the previous comment. When I called the number, the recorded voice did not identify the company, but did ask if I wished to be removed as a "customer," so I chose to be put on their do-not-call list. BTW, I am in Oklahoma.
Basically same as OJKJR. This was a call to my cell phone which had been my business phone number before retiring 4 years ago. It appears this caller (telemarketing company?) is using or purchasing old business phone lists. Checked the caller ID, but no name, which brought me to this website.
