No, no, no. You do not call someone and leave a voicemail more than 60 seconds long to let them know you sent them a meeting invite and who else they invited and would I please accept the invite. You do not do that. That is only slightly less bad than calling to ask if I got your email. If I'm free, I will accept your invite, or I'll ask you to give me more detail about the meeting request. (Your voicemail did not give me more detail, it gave me slightly less.)
