About this page. Clinic OS Pro uses SMS in two distinct contexts: (1) platform-to-account-holder messages from A-Caliber Inc. to clinic owners using our SaaS, and (2) clinic-to-patient messages sent by individual physical therapy clinics to their patients. Each channel has separate phone numbers, separate consent flows, and separate carrier registrations. Both are described below.
| Platform → Account Holder | Clinic → Patient | |
|---|---|---|
| Sender | A-Caliber Inc. (operator of the Clinic OS Pro SaaS) | Individual clinic that subscribes to Clinic OS Pro |
| Recipient | Clinic owner / staff member with a Clinic OS Pro account | Patient of that clinic |
| Phone number | +1 (833) 819-3733 — one shared toll-free number registered to A-Caliber Inc. | A separate per-clinic toll-free number registered under that clinic’s own EIN / business entity. |
| Carrier registration | Single TFV (Toll-Free Verification) under A-Caliber Inc. via Telnyx LLC. | Each clinic completes its own TFV under its own business identity. |
| Consent flow | See section 1 (booking-form checkbox) | See section 2 (five documented paths) |
Why two channels? Clinic OS Pro operates as a technical aggregator under an ISV (Independent Software Vendor) model: A-Caliber Inc. holds the Telnyx account and pays the carrier, but each subscribing clinic registers its own dedicated toll-free number under its own EIN. Carrier reputation, TCPA liability, and patient relationships all attach to the clinic, not to A-Caliber. This is the same architectural pattern used by Twilio + Stripe + Vercel.
SMS messages from +1 (833) 819-3733 are sent by A-Caliber Inc. (an Ontario corporation operating as “Clinic OS Pro”, BIN 1001580753). They originate from a US toll-free number that has completed Toll-Free Verification (TFV) with our carrier partner Telnyx LLC. (TFV is the standard A2P compliance framework for messaging from US toll-free numbers; we do not use 10DLC, which only applies to standard 10-digit long codes.)
This number is used only for direct platform-to-account-holder communications. We do not send marketing or promotional broadcasts from this number. We do not send SMS on behalf of clinics to their patients — those messages come from each clinic’s own separately-verified toll-free number (see section 2).
We will only send platform SMS to a phone number if the recipient explicitly opted in through one of these flows:
Each booking-form consent event is logged with a timestamp and IP address. Consent is not a condition of receiving any service — you can book a call without a phone number, create an account, and use every Clinic OS Pro feature without opting in to SMS. Two-factor authentication on the platform uses a TOTP / authenticator app; no SMS code is involved.
“Clinic OS Pro: Implementation Call in 1h at 2:00 PM EST. Join: https://zoom.us/j/4473767236 Reply STOP to opt out.”
Clinic OS Pro does not send SMS to patients on behalf of a clinic. Instead, individual physical therapy clinics (our customers) use the Clinic OS Pro platform as a technical tool to send SMS messages to their own patients. Each clinic is the legal sender of those messages and is responsible for collecting and maintaining valid patient consent before any SMS is sent.
Patients opt in through one of five paths. Each is recorded in the patient’s database record at the moment of consent with a timestamp, method, and a snapshot of the exact language they agreed to. Once recorded, consent fields are protected at the database layer from accidental modification.
clinicospro.com/c/<clinic-slug>/intake (which proxies to app.clinicospro.com/c/<clinic-slug>/intake), ticks an unchecked-by-default SMS consent checkbox, and submits. The patient’s IP address is also logged for audit. This is the strongest form of consent and is the URL submitted to mobile carriers during each clinic’s TFN verification.The exact paragraph displayed to patients on the public web intake page (path 1 above) is:
“I consent to receive text messages from [Clinic Name], including appointment reminders, treatment-related updates, recall and reactivation messages, and occasional clinic communications. Frequency varies. Msg & data rates may apply. Reply STOP to opt out, HELP for help. Consent is not required for treatment or services.”
[Clinic Name] is replaced at render time with the actual name of the clinic operating that intake page (e.g. “Peak Performance PT”). The text the patient agreed to is captured and locked in the database at the moment of consent and is never modified afterwards.
The bulk-import attestation (path 2) uses an equivalent paragraph confirming TPO consent. Manual front-desk and phone-verbal consent (paths 3 and 4) record the language presented to or agreed by the patient at the time of capture.
At the platform layer, the Clinic OS Pro messaging engine refuses to send any SMS to a patient whose consent record (smsConsentAt) is null. This applies whether the consent was never collected, never recorded, or was withdrawn (Reply STOP). For transactional reminder messages, if no SMS consent is on file but the patient has an email address, the system silently falls back to email. For marketing or reactivation messages, no SMS is ever sent without explicit consent on file. This enforcement runs on every send attempt and is logged.
Once opted in, patients may receive the following message types from their clinic. Frequency varies by clinic policy and patient engagement.
“[Clinic Name]: Hi [first_name], reminder — your visit is [date] at [time]. Reply CONFIRM or call [phone]. Reply STOP to opt out.”
“Hi Sarah, we missed you today at Peak Performance PT. Let’s get you back on the schedule: https://book.peakpt.com”
“Hi Sarah, checking in from Peak Performance PT. How are you feeling? https://book.peakpt.com”
Reply with any of the following keywords to immediately stop all further SMS to your number on whichever channel you received the message:
STOPSTOPALLUNSUBSCRIBECANCELENDQUITOnce any of these keywords is received, the recipient is flagged as opted-out in real time and no further SMS will be sent to that number unless they affirmatively opt in again later. Carrier-level filtering is also enforced by Telnyx LLC.
Reply HELP or INFO to receive a standard response with contact information and opt-out instructions. For the platform channel, the response includes the A-Caliber Inc. support email. For the patient channel, it includes the clinic’s name and contact info.
Msg & data rates may apply. SMS is transmitted over standard carrier networks (AT&T, T-Mobile, Verizon, Rogers, Bell, Telus, etc.). Recipients are responsible for any charges their wireless carrier may apply to incoming or outgoing text messages. Neither A-Caliber Inc. nor participating clinics charge recipients for receiving SMS.
SMS is available to mobile numbers on major North American carriers in the United States and Canada. Some pre-paid plans, VoIP numbers, or landlines may not support text messaging. We do not retry undeliverable messages indefinitely.
Phone numbers, opt-in records, message content, and delivery status are handled under our Privacy Policy (see Section 12 “SMS Consent Records” for the per-patient fields stored for the patient channel). SMS is transmitted via Telnyx LLC. We do not sell, rent, or share phone numbers with third-party marketers. SMS is not end-to-end encrypted; clinics are advised to avoid sending sensitive clinical detail via SMS and to use secure portals for anything beyond appointment logistics.
Clinic OS Pro is designed as a HIPAA-aware platform for healthcare providers. Clinics (covered entities) are responsible for obtaining appropriate patient authorization before sending any Protected Health Information (PHI) via SMS. By default, Clinic OS Pro patient SMS templates avoid clinical detail and financial amounts — messages typically contain only the patient’s first name, clinic name, and general appointment context. Clinics may add additional details, in which case they are responsible for ensuring patient consent covers those disclosures. Our Business Associate Agreement governs our role as a business associate when PHI is involved.
We may update these SMS terms to reflect changes in law, carrier requirements (e.g. Toll-Free Verification rules), or our messaging practices. Material changes will be reflected here with an updated “Last updated” date. By continuing to receive SMS after an update, recipients confirm ongoing consent.
