Horde of the rings

Since my job contract is temporary, I occupy the office room of somebody who is absent for some months. Obviously, I also have inherited his phone number extension. It happens quite often that somebody calls me searching for Petteri. The nice part is that, when I answer, people ask: “Petteri?!”! That makes me wonder. Either my voice is SLIGHTLY masculine or the guy is temporary away for a surgery in Casablanca.
