left a message on my cell phone, all I heard was press 2 to discontinue calls

I have a friend who pays for and uses Skype, an internet based voice over IP product.  He called my phone today and I saw the phone number as 262-312-1026.  He told me Skype has a whole bunch of numbers they use for routing calls from Skype users through when they call regular phone numbers.

I'm 15 and this person called my cell phone.  I did not answer and there was no message.  wierd.
