Yeah, it's from eGain, they call you relentlessly once you check out one of their white papers. Doesn't seem to matter how often you tell them you're not interested, a different person calls every other day.
They called and told me they were from Aegean Corporation. They said they emailed me as well, so I said I'd rather just read the email than talk to them. However, I never got an email and won't be surprised if I get another call soon. Very annoying.
