Missed-Call Text-Back for Contractors
Understand the missed-call acknowledgment workflow, consent checks, duplicate prevention and the human follow-up still required.

An acknowledgment starts a conversation
A missed-call text-back sends an acknowledgment after an eligible unanswered call. It can let the caller reply with context while the business is unavailable. It does not answer the original call, diagnose the job, book an appointment or guarantee that the person replies. Someone at the business still needs to read and answer the response.
- An unanswered call reaches the configured business number.
- The system checks the sending rules, consent eligibility, suppression list and duplicate prevention.
- If eligible, it sends one acknowledgment identifying the business and how to opt out.
- Replies reach the contractor for human follow-up; failures need a visible alert.
What a restrained acknowledgment might say
For an eligible recipient who has consented to this messaging use, an illustrative message is: “This is the service team at your contractor. We missed your call. Please reply with the service you need, or call us again. Reply STOP to unsubscribe.” Replace the generic sender with the real business name before use. Do not add an unconfirmed response time or appointment promise.
Check consent before treating a call as a text trigger
Do not treat every missed call as permission for automated texts or later promotions. The implementation needs an appropriate consent process for the message and a record of that consent. Twilio’s current policy requires consent, sender identification and an accessible opt-out; promotional messages have separate requirements. Read Twilio’s messaging policy for that provider’s rules. Other providers and applicable law also need review before activation.
Check the phone setup before buying another tool
Identify the business number, existing phone or field-service software, where messages appear and who will answer them. A working automation in your current tools may already cover the need. Confirm whether the number and provider can support the intended setup and required registration. A tool subscription alone is not evidence that messages will deliver.
Test the exceptions as well as the successful send
Check an eligible missed call, an answered call, a repeated call, an opted-out number, a reply and a failed delivery. Repeated calls should not create a stack of acknowledgments. An opt-out must suppress later messages. Confirm the alert reaches the person responsible and that the business can see the reply. These are configuration checks, not a substitute for the consent review.
What Airlocked Solutions sells
Inquiry Follow-up & Reviews includes one eligible missed-call acknowledgment and one request after a job is marked complete, plus defined upkeep. It is $150/month plus $300 setup; phone and messaging charges are separate. Monthly billing begins after both automations pass testing. The contractor answers replies and records job completion. This is separate from public Google review responses and from the website subscription.
