Business phone system questions, answered

Falls Technology Services · Idaho Falls · November 12, 2026

The questions small businesses ask most about moving to an internet phone system (VoIP), with straight answers.

What is a VoIP phone system?

A phone system that runs over your internet connection instead of old phone lines. Calls can ring desk phones, phone apps or both, and voicemail can arrive in your e-mail.

Business phone systems (VoIP)

Can I keep my business phone number?

Usually, yes. Your number is moved ("ported") to the new service, which typically takes from a few days to a couple of weeks. Keep the old service on until the move is finished.

Do I need desk phones, or can we use our cell phones?

Either, or both. Phone apps let staff answer the business line on their cell without giving out their personal number. Desk phones suit a front desk or a busy office.

What happens to our phones if the internet goes down?

Most internet phone services can send calls to a cell phone when your office is offline, so customers still reach you. Set that up before you need it.

Can we text customers from our business number?

Often, yes, but in the US business texting from a regular number needs to be registered with the carriers first, and customers must agree to receive texts. Plan a few weeks for the registration.

Will calls be clear?

Call quality depends mostly on your office network. A good router, enough upload speed and phones on a wired connection where possible keep calls clear.

Can calls ring different people at different times?

Yes: calls can ring the right people during open hours, go to a menu or voicemail after hours, and forward to a cell phone.

What about 911?

Internet phones need the right address registered for emergency calls, and it must be updated if a phone moves. We set that up with the system.

Who should own the phone account?

Your business. The phone service account should be in your business's name, with you as the owner, so the number stays yours.
