Team sizes at physician practices in Oklahoma

61.8% of Oklahoma's physician practices with employees had fewer than five people in March 2023, compared with 52.7% nationally. 79.6% 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.

What physician practices in Oklahoma use the phone for

Physician offices field a steady stream of scheduling, prescription refill and test-result calls, and the same few staff members usually answer all of them. Routing calls to the right person and capturing clear messages keeps the waiting room and the phone lines moving.

Calls a medical practice in Oklahoma might handle in a typical week include:

Business texting for physician practices

Practices typically text appointment reminders, arrival instructions and requests to call the office, keeping clinical details for secure channels.

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

What a phone system costs a medical practice in Oklahoma

Physician practices in Oklahoma average 9.3 employees, so the comparison uses a 9-person team. On a per-user plan that headcount sets the bill: $224.55 a month on Ooma Office Pro or $270.00 on RingCentral RingEX Core at list price (checked September 28, 2026). Callata comes to $179.00 a month for 9 users ($99 a month with 5 users included, then $20 per additional user), below both.

Over a year, that is $1,092 less than RingCentral for a medical practice in Oklahoma of that size. Annual contracts lower some competitors' prices, so compare the plan you would actually sign.

Competitor prices are each vendor's published month-to-month list price per user for its lowest plan that includes business calling and texting, checked September 28, 2026: Quo Starter $19, Nextiva Core $23, Ooma Office Pro $24.95 (Essentials excludes texting; one-time $29.95 activation not included), Dialpad Standard $27, RingCentral RingEX Core $30 ($20 billed annually). Prices exclude taxes and fees and may change; annual contracts lower some competitors' prices.

How Callata works for physician practices in Oklahoma

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 Oklahoma 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.
