Do I have a stalker? If yes, is he benign?

[thereject]

I just received a call from a restricted number. My cellphone rang, and I answered it as I occasionally do. "Matt Zeppa speaking" says I. "Can you send me to Matthew's voicemail please?" responds the caller.

Umm... what?

I told him to call back and I won't answer it. He hasn't called back yet, but I am anxiously awaiting whatever strange revelation he has for me.
