45.5% of Colorado's optometry practices with employees had fewer than five people in March 2023, compared with 47.9% nationally. 78.4% had fewer than ten. At that size the phone is shared, so routing (who rings, when, and what happens after hours) matters more than the number of desk phones.

Calls an optometry practice in Colorado 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 Colorado as much as anywhere.

A few of the calls that come in to optometry practices in Colorado:

Business texting for optometry practices

Optometry offices text patients when an eyewear or contact lens order is ready for pickup, along with appointment reminders.

Texting from a local number in Colorado requires carrier registration (10DLC), a one-time $49 fee on Callata.

How Callata works for optometry practices in Colorado

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.

Porting a number you already use in Colorado is free, and business texting is available once the carrier registration (10DLC) is approved; the registration carries a one-time $49 fee. Which specific numbers are open in a given area code depends on carrier inventory at the time you sign up.

AI agents are optional: an AI receptionist or scheduler can pick up when the team is busy or closed, take a message, send a text or email, or transfer the call. They draw on prepaid AI minutes ($0.25/minute), disclose that they are AI, and outbound AI calls require prior consent and are limited to 8am–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.
