Dirtbags!!!  I NEVER answer calls when I do not recognize the caller ID.  These idiots left a computer-generated voicemail message saying they are hiring for telemarketers!  I deleted the message BEFORE I had to listen to any more of their crap.

Robo-call for insurance agents... at least, that's what the first three seconds were before I hung up.

they call daily just linger on the line and then hang up.

they call on a daily basis, just linger on the line for a few seconds and then hang up.

I did not pick it up as I did not recognize the number.  They left a "message" which was just someone taking in a breath every 5 seconds for about 15 seconds. I've saved the number as "don't answer" so I won't be answering again. I've had this phone from SafeLink for less than a week.
