How to set up a business phone system

A business phone system is a separate number for your business, with voicemail, texting, and call routing, that is not your personal cell. It is the difference between a customer calling your business and a customer calling your personal phone at 9 PM on a Sunday.

Short answer

Get a dedicated local business number, register it for business texting, set up simultaneous ring so you or your team pick up, turn on missed call text back, route after hours calls to your AI, and log every call to your CRM. A business phone keeps work and personal separate and stops missed calls from becoming missed customers.

Why it matters

Your phone number is how customers reach you. A missed call is a missed customer, and a call that goes to a personal voicemail is a customer who hangs up and calls the next name on the list.

A business number keeps work and personal separate, lets you route and text from one place, and gives you a record of every call in your CRM.

What you need
  • A dedicated local business phone number
  • A VoIP or cloud phone provider (RiverX, OpenPhone, or similar)
  • Your business hours and the rules for after hours calls
  • A plan for texting customers, including A2P 10DLC registration
  • Your current carrier account info if you want to forward or move your number
Step by step
  1. 1

    Get a local business number

    Get a number with a local area code, not an 800 number and not your personal cell. Customers answer local numbers. They ignore 800 numbers and they definitely do not want to call a personal cell. If you serve one town, get a number with that area code. If you serve a region, get one with the main area code your customers use. A local number builds trust before you even pick up.

    1. 1. Sign up with a VoIP or cloud phone provider, like RiverX or OpenPhone.
    2. 2. Search for available numbers by area code.
    3. 3. Pick a local number, not an 800 number and not your personal cell.
    4. 4. Test it by calling it from another phone to make sure it rings.
    Example

    You serve Bakersfield, so you pick a 661 number. Customers see a local area code on caller ID and answer. An 800 number gets ignored, and your personal cell gets calls at all hours.

  2. 2

    Register for business texting

    If you want to text customers from your business number, you have to register with the carriers through a process called A2P 10DLC. It is a requirement from the phone companies, not a suggestion. Without it, your texts get blocked or flagged as spam. It takes a couple of weeks and requires your business tax ID. Start it the day you get your number, because you cannot text legally without it.

    1. 1. In your phone provider, look for messaging or SMS setup and start the A2P 10DLC registration.
    2. 2. Enter your business legal name, tax ID (EIN), and your messaging use case.
    3. 3. Wait for the carriers to approve it, usually 1 to 2 weeks.
    4. 4. Do not send business texts until it is approved, or they get blocked.
    Example

    You start the registration the day you get your number. Two weeks later it is approved and your texts go through. If you skip it, your first appointment reminder text gets flagged as spam and the customer never sees it.

  3. 3

    Record a professional greeting

    Record a real voicemail greeting that sounds like a business, not a personal one. 'You have reached [Company], leave a message and we will call you back' beats 'Hey, leave me a message.' If you have an IVR menu, keep it short. 'Press 1 for service, press 2 for billing' is fine. Do not build a six option menu that makes customers hang up before they reach anyone.

    1. 1. Open your phone provider's voicemail or greeting settings.
    2. 2. Record a short greeting: company name, a promise to call back, and the hours.
    3. 3. If you use an IVR menu, keep it to 2 or 3 options.
    4. 4. Call your number and listen to it to make sure it sounds like a business.
    Example

    Your greeting: 'You have reached Valley Plumbing. Leave your name, number, and what is going on, and we will call you back during business hours. For emergencies, press 1.' That sounds like a business. 'Hey, leave me a message' does not.

  4. 4

    Set up simultaneous ring

    Set the business number to ring your office phone and your mobile app at the same time, so whoever is available picks up. If it only rings the office and you are on a job, you miss the call. If it rings both, you or your office person gets it. Do not forward it to your personal cell alone, because then it is your personal cell and you are back to the original problem.

    1. 1. In your phone provider, find call routing or simultaneous ring.
    2. 2. Add your office phone and your mobile app as ring targets.
    3. 3. Set them to ring at the same time, not one after the other.
    4. 4. Test it by calling the business number from another phone.
    Example

    A call comes in. Your office phone and your mobile app both ring. You are on a roof, so your office person picks up. Without simultaneous ring, the call rings the empty office and goes to voicemail while you are 30 feet up a ladder.

  5. 5

    Turn on missed call text back

    When a call is missed, the system should text the caller automatically. 'Hey, this is [Company], sorry we missed your call. How can I help?' Most callers text back and you save the lead. Without this, a missed call is a lost customer who already moved on to the next company. This one feature catches the leads you would otherwise never know called.

    1. 1. In your phone provider, find missed call or auto reply settings.
    2. 2. Turn on the automatic text back for missed calls.
    3. 3. Write a short message: company name, an apology, and an ask for what they need.
    4. 4. Test it by calling your number and hanging up before anyone answers.
    Example

    A caller hangs up before you pick up. The system texts: 'Hey, this is Valley Plumbing, sorry we missed your call. How can I help?' They text back 'my sink is leaking' and you have a lead instead of a lost call.

  6. 6

    Route after hours calls to the AI

    Set calls that come in after hours to route to your AI receptionist instead of voicemail. The AI answers, books the job, and texts you a summary. The alternative is a voicemail that nobody checks until morning, by which point the caller has already called someone else. After hours routing to the AI is how you capture the leads that come in at night and on weekends.

    1. 1. Set your business hours in your phone provider.
    2. 2. Find the after hours or closed hours routing rule.
    3. 3. Point it at your AI receptionist instead of voicemail.
    4. 4. Call your number after hours to confirm the AI picks up.
    Example

    A leak call comes in at 11 PM. The AI answers, books the inspection for the next morning, and texts you the address. Without after hours routing, it goes to voicemail, the caller calls the next plumber, and you never knew they called.

  7. 7

    Enable texting on your main number

    Customers want to text, not call. Make sure your main business number can receive texts, not just calls. If a customer texts your number and gets a 'this number does not accept texts' error, they give up. Turn on SMS on the business line so a customer can text the same number they would call. Most phone systems let you do this, but you have to enable it.

    1. 1. In your phone provider, find SMS or messaging settings for your main number.
    2. 2. Turn on inbound texting.
    3. 3. Make sure A2P 10DLC registration is done first, or texts get blocked.
    4. 4. Text your own number from another phone to confirm it works.
    Example

    A customer texts 'are you open Saturday?' to your business number. It comes through in your app and you answer in a minute. If texting is off, they get an error and call the next company instead.

  8. 8

    Log every call and text to the CRM

    Every call and text should be logged against the contact in your CRM automatically. If you have to type it in, you will not. If the phone system logs it, you have a record of every conversation and you can see what was said last time the customer calls back. A phone system that does not talk to your CRM is just a phone. One that does is a sales tool.

    1. 1. Open your phone provider's integrations or CRM settings.
    2. 2. Connect it to your CRM, or use Zapier if there is no direct integration.
    3. 3. Map calls and texts to the contact record by phone number.
    4. 4. Make a test call and check that it shows up on the contact in the CRM.
    Example

    A customer calls back a week later. You open their contact and see the last call, the texts, and what they asked about. Without logging, you start from scratch every time and ask them to repeat themselves.

  9. 9

    Train the team on transfers

    If you have a team, teach them how to transfer a call without hanging up on the customer. A warm transfer, where you introduce the caller to the next person, is better than a cold transfer where the customer has to start over. Most customers who get dropped on a transfer just call the next company. Train the team once and the transfers stop losing you jobs.

    1. 1. Show your team the transfer button in the phone app.
    2. 2. Teach warm transfers: tell the next person who is on the line before you hand it off.
    3. 3. Practice it with a test call.
    4. 4. Remind them never to cold transfer a new lead, who will just hang up.
    Example

    A caller needs billing. Your office person says 'let me get you to our billing person, one moment,' tells the billing person who is calling, then hands it off. The customer does not have to repeat themselves. A cold transfer makes them start over, and some just hang up.

    Set up voicemail to email

    Have your voicemails sent to your email as audio files and transcripts, so you can check them from your phone instead of calling in to listen. If you have to call your own voicemail to check messages, you will not check them often enough. Voicemail to email means you read them the moment they come in and you call back faster.

    1. 1. In your phone provider, find voicemail notification or email delivery settings.
    2. 2. Enter the email address where you want voicemails sent.
    3. 3. Turn on transcripts if the option is there.
    4. 4. Leave yourself a test voicemail and check that it arrives in email.
    Example

    A voicemail comes in at 6 AM. It shows up in your email as a transcript and an audio file. You read it on your phone before you finish your coffee and call back before the customer calls the next company. Without it, you do not check voicemail until noon.

  11. 11

    Forward your current number

    If you already have a business number with a carrier like Verizon, AT&T, or T-Mobile, you do not have to give it out to everyone again. Forward it to your new business number so calls ring through the new system, with texting, logging, and after hours AI. You can also port the number in and move it completely, which takes a few days and frees you from the old carrier. Either way, keep one number your customers already know.

    1. 1. Decide: forward your current number, or port it in and move it.
    2. 2. To forward, dial the activation code for your carrier, then your new business number.
    3. 3. To port, request a transfer in your new phone provider and give it your current carrier account info.
    4. 4. Test by calling your old number from another phone and confirming it rings the new system.

    Codes can vary by carrier and plan. If one doesn't work, call your carrier and they can turn forwarding on for you.

    Example

    Your old number is with Verizon. You dial *72 plus your new RiverX number, and every call to the old number now rings the new system with texting and AI. When you are ready, you port it in and drop the old carrier entirely.

    Copy thisCall forwarding codes (check with your carrier before you use them) Verizon Activate: *72 + your new 10-digit number Cancel: *73 AT&T Activate: *72 + your new 10-digit number Cancel: *73 T-Mobile Activate: **21* + your new 10-digit number + # Cancel: ##002#

    Review the call log weekly

    Once a week, look at how many calls you got, how many you answered, how many went to voicemail, and how many were missed entirely. If you are missing a lot of calls, you have a phone problem and a lead problem. The call log tells you whether your phone system is doing its job, which is making sure you do not miss calls.

    1. 1. Open your phone provider's call log or analytics.
    2. 2. Count answered, voicemail, and missed calls for the week.
    3. 3. If missed calls are up, find out why and fix it.
    4. 4. Check that after hours calls are still routing to the AI.
    Example

    You check the log on Monday and see 12 missed calls last week. Half were after hours and the AI caught them, but half rang the office with nobody there. You turn on simultaneous ring to your phone and the next week the missed count drops.

What to avoid
  • Giving customers your personal cell number instead of a business line.
  • Texting customers without A2P 10DLC registration, so your texts get blocked.
  • A voicemail greeting that sounds like a personal phone.
  • Calls that only ring the office when you are on a job.
  • No missed call text back, so missed calls become lost leads.
  • A phone system that does not sync calls and texts to your CRM.
Common questions
What is A2P 10DLC registration?

It is a carrier requirement for businesses that send text messages from a 10 digit phone number. You register your business tax ID and your messaging use case with the carriers. Without it, your business texts get blocked or flagged as spam. It is mandatory, not optional.

Can I use my personal cell for business calls?

You can, but you should not. Customers call at all hours, you lose the boundary between work and personal, and you have no record of the call in your CRM. A business number keeps it separate and lets you route, log, and text from one place.

Should I forward my current number or move it?

Forwarding is faster and you keep the old carrier. Porting moves the number to your new provider and drops the old bill, but it takes a few days. If your customers already know the number, keep it either way. Do not hand out a new number if you do not have to.

Do I need a separate number for texting?

No. Turn on SMS on your main business number so customers can text the same number they call. Most phone systems let you do this, but you have to enable it, and you need A2P 10DLC registration first.
