I got a call on my mobile phone from 310-487-598.  The last digit was not displayed on my caller ID.  Since the number was not a valid one, I did not pick up.  No voice mail was left.

I received a call from 310-487-598 as well.  No message left either.  Dang, I was hoping it was a job lead!  I shouldn't be getting solicitations, though, as I am on the "Do Not Call" list.

just got a call from 310487598 the last digit was missing I picked up without saying hello and just listened. I did not hear anything, no one spoke up, no backround noise. They hung up within seconds.

I got this call and picked up a few days ago.  A recorded message began, "Hi, this is Dan and I have a special running cleaning your carpets..." so I hung up.  This is infuriating because my number is on the do not call list already.  I got this call on my work phones a few weeks ago and played along.  I pushed the number for more info, and a female voice picked up.  I said I wanted to make an appt for my carpets and she put me on hold and a man's voice in accented English came on.  I said, "Oh, excuse me, I have to go but could you give me your number so I can call back and make the appt?" and he hung up.  Would love for this to stop at work and now on my cel.

Like everyone else on this post, I too got a call from this number (well, sort of number, as it was missing the last digit).  Since I'm always suspicious of calls like this, I didn't pick up.  Likewise, since this is probably a suspect caller with dubious intentions, they didn't leave a message.
