Never answered this kind of weird phone calls so we don't know what is about.

Just got a call from this #, no message left.

It's some "law firm" calling about a past debt.  They called my cell but as I was at work I didn't get the call so they called my husband and woke him up but they didn't leave their name, just said they were a law firm (sorry but I don't buy that for one second).. Sorry but if you don't send me written notification of who you are and what the "debt" is then I will not respond to you as if I'm right that's a clear violation of the FCDA.
