It's from Baynote. This time they left a message asking to get in touch with my superior about attending a webinar (they knew his name...)
They're pushy, and if they are able to get in touch with you (get direct contact info such as your email address), they won't stop calling or emailing you.
I picked up one time, and had to endure a 10 minute sales speech with no way to 'cut-in' to the conversation. Waste of my time and theirs.
