Team sizes at optometry practices in California

49.4% of California's optometry practices with employees had fewer than five people in March 2023, compared with 47.9% nationally. 84.0% had fewer than ten. That is the size of team where a missed call usually means nobody was free, not that nobody was on staff.

Calls an optometry practice in California 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.

Calls an optometry practice in California might handle in a typical week include:

• A parent calls to book a child's eye exam before the school year.
• The office calls patients when an order arrives.
• Someone calls about sudden eye irritation and asks whether to come in.

Calls after closing time

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.

How Callata works for optometry practices in California

Callata is a business phone system priced at $99 a month with 5 users included, then $20 per additional user. Callata Office includes up to 3 local business numbers, unlimited inbound calling, 1,500 pooled outbound US and Canada minutes per user each month, a browser softphone that can also ring your cell, voicemail with transcription, call recording with AI summaries, business-hours routing and E911 on every number.

If you already have a number in California, 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.
