I have instructed my wife who also works from home on how to answer the phone, set up appts. etc. She is great at it and it lends an air of professionalism to the business. If there is a question she can't answer she will give them my cell number or call me herself.
One thing I can never understand is how do you hear the cell phone with a backpack blower? Vibrate mode? With the backpack or mower Iam already vibrating! :-)
