Most VoIP advice for veterinary practices assumes a suburban clinic with a front desk, a full-time receptionist, and an emergency hospital down the street for after-hours referrals. That’s fine if you’re a small-animal practice in a college town. It’s useless if you’re a large-animal vet driving a truck between farms, an equine vet working out of a mobile unit, or a mixed-practice clinic where half the day is spent on the road.
