this number called me and a recording in a female voice started speaking rapid spanish that i didnt understand this is not the first time that this number has called me and i cant seem to find out how to get it to stop

This number just called me.  Did not answer as the number looked funny and my number is new, so not many people should have it. They left no message.

this number called today and when i called back a machine said that this number didnt exist weird !!

Within 5 mins had called 10 out of 65 lines coming into our office.  All hangups when someone picked up the phone.
