Call forwarding for a small shop, set up in five minutes.

Three kinds of forwarding

Almost every phone carrier offers the same three options, though the names change. Always forward sends all calls to another number right away. Forward when busy sends the call along only if you're already on a line. Forward when unanswered sends it after a number of rings, and this one is usually what a working owner wants.

Always forward makes sense for a day off or a vacation week. For daily use, pick unanswered. The phone still rings for you first, and a second phone rings only if you can't reach yours.

The five-minute setup

The exact steps depend on your carrier, but the shape is the same.

1. Decide where calls should go. A second mobile, your office manager's phone, a partner's phone. Not a number nobody checks.
2. Find the setting. Look in your carrier's app under call settings, or dial the code your carrier publishes for forwarding when unanswered. A search for "[your carrier] forward unanswered calls" will find it.
3. Set the ring count. Four rings, roughly twenty seconds, is a good starting point. Fewer cuts you off while you're reaching for the phone. More lets the caller give up.
4. Save and write down the code that turns it off. You will want it later.
5. Tell the person who will pick up. They should answer with the shop's name, not "hello."

Test it before you trust it

Call your own number from a different phone and don't answer. Count the rings. Confirm the second phone rings, and that whoever answers says your shop's name. Then do it again from a number the second phone doesn't recognize, since some phones silence unknown callers.

Test again at the hour you most need it, usually early evening, and again on a Saturday. A forward that works at noon and fails after hours has fixed the wrong problem.

Mistakes that send callers nowhere

Forwarding to a phone that is on silent. Forwarding to a number that goes to a full voicemail box. Forwarding in a loop, where phone A forwards to B and B forwards back to A, which ends in a busy tone or a dropped call. Forgetting that carrier changes, such as a new plan or a new SIM, can reset the setting.

Also check that your shop's caller ID shows properly. If the second phone sees only "unknown," the person answering has no idea whose line it is.

What forwarding can't do

Forwarding moves the ringing. It doesn't add hands. If the second person is also under a sink or behind a counter, the call just rings in a second place. At that point you need someone, or something, that answers when nobody can. For many shops the next step is to read answering service vs a phone assistant and decide which suits the business.

Who should pick up the second phone

Choose the person for temperament, not title. The best answerer is calm, polite and knows the shop. A spouse, a front-desk person, a senior tech or an apprentice can all do it with a one-page sheet. The sheet should list your hours, your service area, what you don't do, and the three questions to ask every caller.

Write the greeting for them as well: "Thanks for calling Ridgeline Plumbing, this is Maria." The first five seconds set the tone, and a customer who hears a business name relaxes.

Plan for the days it will fail

Phones die, batteries run low, and people go to lunch. Decide in advance what happens when the second phone doesn't answer either. A voicemail with a clear greeting is the minimum, as described in the 30-second greeting. A third number is better if you have a partner.

Once a month, repeat the test call. Carriers update their systems, people change phones, and a setting that worked in spring can quietly stop working in fall. Put the check on the same day as your invoices so it doesn't get forgotten.

If you use a business phone app or a landline

Business phone apps and office landlines often have their own forwarding rules, set in the app or on the provider's web page rather than through the carrier. Look for words like "call flow," "ring groups" or "find me." The idea is the same: ring the main phone first, then another, then voicemail.

If you have a landline with no forwarding option, ask the provider what they offer, or consider moving the number to a service that does. Keeping the number is the main thing. Customers have it on trucks, cards and listings, and changing it costs more than any phone fix.

A short checklist before you leave it

• The second phone is charged and has the ringer on.
• The person who will answer has your sheet.
• You wrote down how to turn forwarding off.
• You tested at least once from a stranger's phone.
• A reminder to retest next month is in your calendar.

Where Centera comes in

Centera sets up Nora, a phone assistant that picks up the calls you don't, in your shop's name, English or Spanish. You keep your number and forward the unanswered calls to the line we set up. See the missed-call page for HVAC shops for one example of how it reads in a working trade.
