VOIP for Dental Offices: What Actually Matters
I've run 6 practices for 6 years now, and I've switched phone systems more times than I'd like to admit. Most "VOIP buyer's guide" content online covers the same three points — HIPAA, integrations, cost — and stops there. Those matter, but they're not what actually bites you six months in. Here's what I'd actually check.
Per-user pricing vs. flat rate
Some providers charge per seat. Others charge a flat rate for the whole office regardless of how many lines you run. Per-seat sounds fine until you add a temp hygienist, a seasonal front desk hire, or a second line for recall calls, and your bill jumps every time. Dental offices turn over front desk staff a lot — that per-seat model compounds faster than people expect. Flat-rate protects you from that but sometimes caps how many concurrent calls you can actually run, which is its own problem on a busy Monday. Ask for both numbers before you compare anything else.
The app is usually worse than the pitch
Nobody demos this properly. Ask to actually use the mobile app for a week before signing, not watch someone click through it on a call. I've had systems where notifications lag by 10-15 seconds, where you can't tell a call is from a patient vs. a robocall until you pick up, or where forwarding a call to your cell strips the caller ID so you have no idea who you're calling back. If a doctor wants to take a call from home without handing out their personal number, test that flow specifically before you buy.
Concurrent call capacity, not just "seats"
Three front desk staff doesn't mean three simultaneous calls. Some plans cap concurrent calls separately from user seats. Find out the actual number, then think about your worst Monday morning — after a holiday, after a snow day — and check if that number holds up. This is the gap that shows up as busy signals during your highest-value call volume, which is exactly when you can't afford it.
Fax still breaks
You still fax referrals, prescriptions, and insurance paperwork to specialists and labs. Fax over VOIP is unreliable — dropped pages, garbled scans — more often than any vendor will volunteer. Ask specifically how they handle fax, and if the answer is vague, keep a separate analog line or efax service rather than assuming it'll just work.
Number porting and your E911 address
Porting your existing number takes 2-4 weeks, and if you do it mid-transition without a plan, you lose calls during the gap. Also — VOIP ties your emergency address (E911) to whatever's registered in the system, not your physical location automatically. If you move a router, add a location, or set someone up to work remotely, that address needs to be updated manually or 911 calls route to the wrong place. Ask how they handle this, because most offices find out the hard way.
HIPAA and integration — still non-negotiable
Get the signed BAA. Confirm where recordings and voicemails are stored and who can access them. For integration with Dentrix, Eaglesoft, or Open Dental, don't take "we integrate" at face value — ask if that means caller ID pulls the chart automatically, or just that data exports on a schedule. Those are very different products wearing the same word.
Also check if call recording is even legal the way they've set it up. Lot of states require two-party consent, so there should be an automatic disclosure on the line before recording starts, not something you have to configure yourself and probably forget. And ask if the integration writes anything back into the chart, or if it only reads from it. Read-only means your team is still logging calls manually in the PMS after the fact, which defeats half the point of paying for the integration in the first place.
Contract terms
Read the terms properly, not just the pitch. "Month to month" can still mean a 30-day notice period, which in practice means you're paying for close to two months once you factor in billing cycles and the notice window; that's not the same as canceling and walking away the same day. Also check what happens if you don't return their devices on time after you cancel. A lot of contracts have a fee attached to that, and it's usually buried far enough in the fine print that nobody catches it until the invoice shows up.
Bottom line
This is close to why we built the Dental Tech Hub in the first place. Editorially classified means you're pointed toward what fits your situation, not whoever paid to rank first. If you'd rather skip the research, Mola can walk through your setup and point you toward vendors worth an actual conversation.
