This page documents how end-user SMS consent is obtained through the Availon platform.
Availon is a missed-call response service for local service businesses. Consent to receive SMS is obtained through an explicit verbal opt-in via IVR keypress (DTMF). When a call to a business goes unanswered, the caller hears an automated greeting that identifies the business by name and prompts them to press 1 on their keypad to receive a text message. Only callers who actively press 1 receive SMS. Callers who do not press 1 are directed to voicemail and receive no text messages. No SMS is ever sent without this explicit opt-in action.
Consent is obtained through an IVR verbal opt-in process:
This IVR DTMF keypress constitutes express verbal consent per TCPA guidelines. A complete audit trail of the keypress event, timestamp, and caller phone number is maintained for every opt-in.
After pressing 1, the consumer receives one SMS containing:
Additional messages are sent only if the consumer chooses to reply and continue the conversation.
Consumers may opt out at any time by replying any of the following keywords: STOP, STOPALL, UNSUBSCRIBE, CANCEL, or QUIT. No further messages will be sent after opt-out. Consumers may re-subscribe by replying START or UNSTOP. Reply HELP at any time for assistance. All opt-outs are honored automatically and immediately across every business number on the platform.
One message per missed-call opt-in. Message frequency varies — additional messages are sent only if the consumer initiates further conversation by replying.
All Availon business subscribers agree by accepting the Terms of Service to use the platform solely for follow-up communication with consumers who have explicitly opted in via the IVR keypress on a call to their business. Outbound cold messaging is prohibited and is grounds for account termination.
This disclosure supplements the primary IVR verbal opt-in. The IVR keypress (Press 1) is the primary consent mechanism. The following is the disclosure language Availon recommends all business subscribers display alongside their advertised phone number on any public-facing property:
“If your call is not answered, you may be offered a text-back option. Press 1 when prompted to receive an SMS so we can help you right away. Reply STOP to opt out, HELP for help. Msg & data rates may apply. Msg frequency varies. See our Privacy Policy and Terms of Service for details.”
Caller dials the business number.

One SMS is sent containing the business name, an offer of assistance, STOP/HELP keywords, the “Msg & data rates may apply. Msg frequency varies.” rates disclosure, and links to the Terms of Service and Privacy Policy.
Caller is directed to voicemail. No SMS is sent.
Express consent for SMS is established at the moment the caller presses 1 on their keypad during the IVR prompt. The DTMF keypress event, the caller’s phone number, the business identifier, and a UTC timestamp are recorded for every opt-in and retained for the lifetime of the account.
