Before you start clicking buttons, it helps to sketch out what should happen when someone calls your business. This is your call flow — the path a call takes from the moment it arrives until someone answers or the caller leaves a message.
You don't need any technical knowledge to plan one. This guide walks through the building blocks in the order a call actually travels.
The four building blocks
Almost every business phone setup is made from the same four pieces:
| Building block | What it does | Where you set it up |
|---|---|---|
| Front door number | The phone number customers dial | Phone Numbers → Your Numbers |
| Voice menu | The recorded menu ("Press 1 for Sales…") | Phone System → Voice Menus (IVR) |
| Ring group or call queue | The team of people who actually ring | Phone System → Ring Groups or Call Queues |
| Voicemail | Where a call lands if no one answers | Phone System → Mailboxes |
A call flows through them left to right: the number rings, the menu answers, the caller's choice sends them to a team, and voicemail catches anything that isn't picked up.
Step 1: Start with the front door
Pick the number customers call most — often your main business line. Everything else hangs off this number. If you have several numbers (sales line, support line, a location number), you can give each its own call flow.
Step 2: Decide if you need a voice menu
A voice menu (also called an auto-attendant) greets callers and offers choices: "Press 1 for Sales, Press 2 for Support, or stay on the line for the operator."
- Use a menu if callers need to reach different departments, or you want a polished greeting.
- Skip the menu if you're a small team and every call should just ring the same people. In that case, point your number straight at a ring group.
Step 3: Choose how people ring
When a call needs a human, it goes to one of these:
- Ring group — rings a set of phones. You choose whether they ring all at once, one after another, or take turns. Best for teams up to a dozen people.
- Call queue — holds callers in line with hold music and "you are caller number 3" updates while your agents finish other calls. Best for busy support or sales desks where calls stack up.
Not sure which? See Ring Groups vs. Hunt Groups vs. Call Queues for a side-by-side comparison.
Step 4: Plan the safety net
Decide what happens when nobody picks up. Every ring group and queue lets you set a fallback — usually voicemail, but it can also forward to a cell phone or play a closing message. Callers should never hit a dead end.
Step 5: Plan for after hours
Calls that arrive when you're closed should be handled differently — a "we're closed" greeting, a voicemail box, or a forward to an on-call phone. You set this up per location under Organization → Business Locations → Night Service. See Route Calls After Hours and on Holidays for the how-to.
Put it on paper first
A simple sketch saves a lot of rework. For a typical small office it might read:
Main number → Voice menu greeting →
- Press 1 → Sales ring group → voicemail if unanswered
- Press 2 → Support call queue → voicemail if unanswered
- Press 0 or wait → Reception ring group → voicemail
- After hours → "We're closed" greeting → main voicemail
Once you have that, building it is just following the map. Set up the pieces from the bottom up — voicemail boxes and ring groups first, then the voice menu that points to them, then attach your number.
