We have two lines, one main line and one just for techs. On the main line, I answer "Good [Morning/Afternoon/Evening], this is Doctor Micro, how may I help you?"
If a caller somehow gets the technicians line and the technician answers it, the greeting is "Doctor Micro Technician's line, how may I direct your call?"
The voicemail answer on the technician's line is, "You have reached the Doctor Micro Technicians line. If you are calling about an appointment you have already scheduled, please stay on the line and leave a message. Otherwise, please hang up and call the main Doctor Micro number at (XXX) XXX-XXXX. Thank you"
