Switching Phone Providers Without Missing a Call

You can switch phone providers without missing a single call. The trick is the order: keep your old service running, set up and test the new system while your number moves over, and cancel the old account only after calls are ringing on the new one.

Switching phone providers feels risky because the phone is how customers reach you. With a little planning, the only thing customers notice is that you sound more organized.

What Should You Do Before You Cancel Anything?

Nothing gets canceled first. Start with a little homework:

• List every number you pay for. Main line, direct lines, fax and toll-free numbers. Your latest bill is the best source.
• Write down what each number does. Who it rings, what callers hear and where voicemail goes today.
• Check for equipment on a phone line, like an alarm panel or an old card terminal. Talk to that equipment's vendor before you change anything.
• Check your current agreement for any notice period or fees for ending service, so there are no surprises.

How Do You Keep Your Number?

Almost every business can keep its number. Moving it to a new provider is called porting, and with Telonium it costs $10 per number, one time. You sign a form online that lets us move your number, using the account details from your current bill. Some phone companies also ask for a transfer PIN from your current phone company, so request it early.

We cover each step in detail in how to keep your business number when you switch. You can also check right now whether your number can move on our keep your number page.

Can You Test the New System First?

Yes, and you should. While your number is moving, set up everything else:

• Add your users and install the Telonium app on their computers and cell phones.
• Record and upload your greeting, and build a short phone menu.
• Set up call groups so the main number rings the right people.
• Set each number's schedule for open hours, after hours and any holiday hours coming up.
• Check that voicemail goes to the right email inboxes.
• Make test calls between your team and to your own cell phones.

If desk phones are part of the plan, they arrive set up, usually in 3 to 5 business days, so order them early. Our small office phone system guide walks through the setup choices.

What Happens on Switch Day?

You get a date once your current phone company confirms it. On that day, calls to your number start ringing on the new system. For a short while some calls may still reach the old one, which is another reason to keep it running until the end of the day.

Once the switch happens, run a quick check:

• Call your main number from a cell phone and listen to the greeting.
• Try each menu option.
• Leave a voicemail and confirm the email arrives.
• Make an outgoing call and check it shows your business number.
• Send a test fax if you moved a fax number.

Only after all of that works, call your old provider to close the account and stop billing.

What Should You Tell Your Team?

A short note a few days before switch day saves a lot of questions:

• The switch date, and that customers will not notice anything.
• How to sign in to the app, and to call customers from it so they see the business number.
• How to transfer a call and put someone on hold.
• Who to tell if something sounds wrong.

Pick a quiet week for the switch, not the Monday of your busiest month. Have one person own the checklist from start to finish.

Frequently Asked Questions

Should I Cancel My Old Service Before Switching?

No. Keep it active until your number is ringing on the new system. Canceling early can disconnect the number.

How Long Does a Switch Take?

Signing up takes about ten minutes online, and accounts are usually approved within one business day. Moving the number usually takes one to two weeks, and we confirm the exact date with your old phone company. You can start using Telonium before the move finishes.

Can We Use the New System Before the Number Moves?

Yes. Set up users, greetings and call groups, install the apps and make test calls, so everything is ready on switch day.
