Is it possible to find out who is using 141 to call me?

been receiving over 20+ call from a withheld number. I think i have an idea who it may be but cannot contact this person. If it is who i suspect they would be using a LANDLINE to make the calls! is there any way to reveal their number? or find out? I called local police they said nothing they can do! but thought you guys mite have a lil mre info?
