I prefer the phone ring at my office where the best Salesperson I have ever met works...my wife. If she takes the call the job will be booked and they will already believe I'm the most amazing Carpet Cleaner who has ever lived when I show up. She will mention our other services and leave extra time if they want me to look at their upholstery or whatever as an add on. I'm a good on location Salesperson. When the phone does get forwarded to me because Ann has to be out of the office, I don't do as well...especially if I'm on a job.
Sounds pretty similar to the way we operate!
Check out Ring Central. It's like $9 per month and extremely versatile and customizable.
We forward the business line to voicemail in the non working hours.
Calls go to Mel in the office. If she's on the other line, or unable to answer, then they come to me.
How many rings? Ring simultaneously between a couple users? Hand off a phone call?
All kind of features, most we probably don't even use.
I know it's a biz call because it says "The Clean Machine" on my newfangled but classic iPhone SE.
