Receiving calls on cell phone from this number...pls tell them to stop

This number continues to call my work cell over and over one call after the other and it is nothing but a fax tone! RRRRRRR!!!!

fax tone over and over

I, too would like to stop these annoying calls.  Last night they called three times between 4:00 and 4:30 a.m. -- and I had to preach and lead worship the next morning.  

Is this some sales company randomly dialing numbers to send fax driven sales pitches?

How do we stop these people?

I have been receiving those calls on my cell phone, too (twice so far today).  I contacted my phone company (no help).  I tried contacting the phone company in FL (no record).  I even contacted the police, as recommended by my phone company (no help).  Finally, I remembered that the FCC is the regulatory body for this type of stuff.  What they are doing is illegal (per FCC regulations).  So, I went to FCC.gov and filed a complaint.  I recommend you do the same.  If they get enough complaints, maybe they will stop the business (or whomever) from calling people like this.  Good luck...
