Call routing

Call routing is the logic a phone system uses to decide where each incoming call should go, based on rules such as time of day, caller choice, location or staff availability.

If call forwarding is a single instruction, routing is the whole rule book. It answers questions like: which phones ring first, in what order, for how long, and what happens next if nobody picks up. A clear routing plan is what turns a handful of phone lines into a dependable front desk.

Common routing rules

Time-based routing sends calls to different places depending on the clock. Office hours go to the desk; evenings and holidays go to night cover.

Ring groups make several phones ring together, or one after another, so whoever is free can answer.

Menu-based routing lets callers choose a destination by pressing a key or saying a word, which is how an IVR works.

Location-based routing matters for groups with more than one clinic. A caller might be sent to the nearest site, or to whichever site has a free receptionist.

Overflow routing passes calls on when the first destination does not answer in time.

Designing routing for a vet clinic

Start with the caller rather than the org chart. Owners want to reach someone who can help quickly, so every extra step should earn its place. Keep menus short. Make sure urgent calls never sit behind a long greeting. And give every route a final destination, so no call ends in silence or a dead extension.

Review the plan whenever something changes, such as new opening hours, a new location or a change of on-call cover. Routing errors are easy to miss because staff rarely call their own clinic.

Testing

Call the clinic from an outside phone at different times of day, including just before and after the switch to night cover, and listen to exactly what an owner would hear.

An example

At a two-vet clinic, calls ring the front desk first, then a phone in the treatment area, and then pass to an overflow answerer. At closing time the routing switches automatically to after-hours cover, and on public holidays a separate rule applies the holiday schedule.

How Tilly handles it

Tilly sits inside your routing as a destination. You choose when it answers: all calls, overflow, after hours or a weekly schedule. A caller who asks for a person is offered a transfer or callback, and if anything fails the call rings through to your own line.
