Getting music onto phone?

I keep getting phone calls with only muffled music playing at the end of the line...?

• I think it is someone pranking my house, it has happened almost 15 times in the past half hour. How can I make this stop? (P.s. I can't not answer or unplug the phone as I am expecting a call from someone else on that phone)

• Answer:

  That happened to my friend before, someone sighned her up on some music thing on the internet and they was sending music to her phone. With people on the line too, it was very strange and I was there. So, maybe that's it!
