How Should a Small Business Set Up Voicemail and Call Routing?

By Bill Stilwell · Last reviewed October 17, 2026

The short answer

Every call should end up with a person or a clear voicemail. Record a greeting with your business name, when you’ll call back, and another way to reach you. Keep any phone menu short, route calls by a simple rule, define what counts as urgent, and always have a backup person.

Why it matters

A caller who can’t reach anyone usually calls the next business on the map. Long menus frustrate people and make some give up. Urgent calls that sit in voicemail can mean real damage for the customer and a bad review for you. And a business that depends on one person’s cell phone stops answering when that person is sick or on vacation.

12.4.1 Voicemail greeting

What it means: the message callers hear when nobody picks up. The outline says it should state the business name, a response expectation, and an alternate option.

How to do it: keep it under 30 seconds. For example: “You’ve reached Bayside Dog Grooming. Leave your name, number, and what you need, and we’ll call you back today before 5. You can also book online at our website.” Record it in a quiet room. Check that the mailbox has space and that new messages notify the right person (see 12.3.4 Call Ownership).

Common mistake: the phone carrier’s default greeting that only reads back the number. Callers aren’t sure they reached the right business.

What it means: the “press 1 for” options. The outline says to keep menus simple and accessible.

How to do it: most small businesses need no menu or two to three options at most. Put the most common choice first. Let callers press 0 or stay on the line to reach a person or voicemail. Offer another way to reach you, like a text number or online form, for people who can’t easily use a phone menu (see 9.7.2 Communication Access).

Common mistake: a long menu copied from a big company, with options that all ring the same phone.

12.4.3 Routing rules

What it means: the rules that decide which phone rings. The outline lists department, service, location, and urgency.

How to do it: write each rule in one line, like “Sales calls ring Maria, then the office line” or “Calls from 5 p.m. to 8 a.m. go to the after-hours message.” Set a ring time, such as 20 seconds, before a call moves to the next person or voicemail. If you have more than one location, route each location’s number to that location (see 14.1.4 Phone).

Common mistake: rules nobody wrote down. When the phone setup breaks, nobody knows how it was supposed to work.

12.4.4 Missed-call response

This line is covered on 16.2.4 Missed-Call Process, which explains how to return missed calls quickly.

12.4.5 Emergency escalation

What it means: how urgent calls are identified and passed to a person fast.

How to do it: define “urgent” in plain words that fit your trade, like “active leak” or “no power.” Give urgent callers a direct path, such as “press 1 if this is an emergency,” that rings the on-call person and then a backup. Write down what the on-call person does next (see 22.9 Emergency Procedures and 16.2.5 Lead Escalation). If a caller describes a life-safety emergency, tell them to hang up and call 911.

Common mistake: an urgent option that rings the same voicemail as everything else.

12.4.6 Backup routing

What it means: a plan for when the main person can’t answer.

How to do it: name a backup person for every routing rule. Set calls to roll to the backup after a set number of rings. When someone is out, update the routing that day, not after a week of missed calls. Keep login access to the phone system with at least two business-controlled people (see 8.4.6 Two Business-Controlled Administrators).

Common mistake: calls forwarded to a former employee’s cell phone because nobody changed the rule.

When to get help from a pro

Your phone system provider can set menus, ring times, and backups. Questions to ask:

Can calls roll to a backup automatically after a set number of rings?
Can I change routing quickly from my phone when someone is out?
Will I get a notice if the voicemail box is full or a call goes unanswered?

Bill’s note

[Bill: add a short note. For example, the voicemail greeting you recommend to clients, or a time a client’s calls were still routing to someone who had left.]

Questions people ask

What should my voicemail greeting say? Your business name, when you’ll call back, and another way to reach you, in under 30 seconds.

Does a small business need a phone menu? Usually not. If you use one, keep it to two or three options and let callers reach a person or voicemail easily.

How do I make sure urgent calls get answered? Define what urgent means, give urgent callers a direct option, and ring an on-call person and a backup.

What happens when the person who answers is out? Calls should roll to a named backup. Update routing the same day someone is out.
