| 5–9 employees | 209 | 36.1% | 32.2% |

Calls an optometry practice in Michigan has to catch
Eye-care offices combine exam scheduling with eyewear and contact-lens orders, so callers want both appointments and order status. Calls about broken glasses or eye irritation also need to reach someone quickly. That holds for optometry practices in Michigan as much as anywhere.
Calls an optometry practice in Michigan might handle in a typical week include:
- The office calls patients when an order arrives.
- Someone calls about sudden eye irritation and asks whether to come in.
- A parent calls to book a child's eye exam before the school year.
After-hours calls
After-hours messages are typically order questions or appointment requests that can be returned the next business day.
Callata voicemail is transcribed and triaged for urgency, and business-hours routing decides where calls go once you close.
What a phone system costs an optometry practice in Michigan
Optometry practices in Michigan average 7.6 employees, so the comparison uses an 8-person team. On a per-user plan that headcount sets the bill: $199.60 a month on Ooma Office Pro or $240.00 on RingCentral RingEX Core at list price (checked September 28, 2026). On Callata the same 8 people cost $159.00 a month, less than either per-seat plan.

How Callata works for optometry practices in Michigan
Callata Office costs $99 per month for up to 5 people, and each additional user is $20 a month. That covers up to 3 local numbers, calling from a browser or your cell, transcribed voicemail, recorded calls with AI summaries, after-hours routing and E911 on each number.
If you already have a number in Michigan, porting it to Callata is free. Texting from a local number requires a one-time carrier registration (10DLC, $49), and the numbers available in any area code depend on carrier inventory when you choose them.
Optional AI agents (receptionist, sales, support or scheduler) can answer calls after hours or when nobody picks up, take messages, text, email and transfer to your team. They are billed from prepaid AI minutes at $0.25 per minute, identify themselves as AI, and may only place outbound calls to people who consented, between 8am and 9pm.
Practices that handle protected health information should review their own privacy obligations before recording calls, enabling AI summaries or texting appointment details, and keep clinical conversations out of text messages unless their policies allow it.
