phone messages

Here in y'old Viacom Towneship, I thought the only people who knew my inside work line were Marisa, Jessica and Joey. But sometimes the little red light on my phone glows red, even though i have only been here two weeks, and when I check my voicemail, it is full of messages from people like Tori Spelling and William Shatner, just calling to holler and remind me to watch their programs. I mean, can they just give out my number like that to people I don't know? Isn't it company policy to protect all personal information from unknown parties? I know I practically grew up with her (much love to you josh k.), but do I really need to get a weekend what's up from Donna Martin?
