call came in as unknown

Missed calls from this number:
- 3/27 @ 6:10pm central
- 3/29 @ 12:39pm central
- 3/31 @ 6:32pm central
- I'm positive there have probably been more.

Didn't pick up any of the times. Today I finally decided to call it back to see what the F*@& was up, and I immediately got a busy signal. Tried again, same result.

me, too, on all of the above.
several calls lately
totally annoying
where are they from?

Called around 0830,only silence was heard until they hung up. No number listed on caller ID, had to ^69 to get the number.

Got a call on SAturday from this number, no message no nothing, i tried to call back several times, no luck.  The origin is out of Michigan and it could be Chrysler or Jeep trying to call me since I have a leased vehicle that is about up and they have called on several occasions to see what my plans are with the leased vehicle.  If you are getting this number and have a leased vehicle, it might be the same scenario.
