I've been getting a few missed calls from anonymous mobile phones. Then this morning I got 3 in a row from the same number. I dialled 141 then the mobile number back and it rang for a while with music playing and birds tweeting in the background. After a bit the other end hung up but the birds tweeting and music kept playing through my earpiece until I turned the phone off and turned it on again.

Is this something to be worried about or is it just a bit of time wasting?

Which phone? What music app do you use?

Samsung and I don't really use it to play music so just the generic Samsung music app.

Very strange.

Remember not all 07 numbers are mobiles.

Did the number start with 070 by any chance?
