this number called our office twice today--the second time they hit my boss' extension but didn't leave a message. if you think it's important enough to call multiple times... leave a voicemail. We get so many solicitor phone calls that we utilize our caller ID and voicemail capabilities even with semi-local numbers if we don't recognize them. If you're actually calling about something relevant... we WILL get back to you. If you can't be bothered to leave a voicemail, please stop calling.
I have received the same call from the same number at least once/day for the past week. I never answer if I don't recognize the caller. I am sure it is a scam.
