When six practices share your block, hold music is a referral
Density means the alternative to you is thirty seconds away in a search result, so answer speed is a competitive position rather than a courtesy.
A caller who reaches voicemail at 12:40 does not usually call back. They tap the next result. In a city where several practices sit within a few blocks of each other, the cost of a missed call is a patient who booked somewhere else before you noticed.
Count the misses first. Most practice phone systems can report unanswered calls by hour. Nearly every office finds the same two holes: the lunch hour and the twenty minutes around opening and closing.
Then close them with coverage rather than a script. Someone covering lunch, a rollover, or an answering service that can actually see the schedule. A message taken by someone who cannot book anything is only marginally better than voicemail.
Missed calls should trigger a text back within a minute or two, in the same thread, from the practice number. People here text. Many will never call again but will answer a message.
