Only the number was displayed, just like this: 551-256-8239. I don't take calls from numbers I don't recognize (or blocked id's and/or numbers), so I let it go to voicemail. They didn't leave a voicemail, so in to the "Telemarketers" contact they go.
Here's a tip: When you get a telemarketer or otherwise-undesirable call, save that number into a contact called "Junk" or "Telemarketers" or "IgnoreThisCall" or whatever. Then, set the ring tone for that contact to "No Ring" or "Silent" or whatever it is on your phone. Then, if they call again, you will see it in your history log of missed calls but you won't HEAR it. Even if you do SEE the call coming in, the contact information will show up as whatever you named it (above), and you will know to ignore it.
Got call two days ago stating that they are collecting donation to assist women who has breast cancer and can no longer afford to buy their medication. I asked to mail me the info and I will review.
