AI Receptionist for GoHighLevel Agencies: Replace Missed Call Text Back with a Voice That Books
An AI receptionist for GoHighLevel answers inbound calls on a Twilio number assigned to a sub-account, greets the caller by the business name, answers questions from a knowledge base, checks live calendar availability, books the appointment, and writes the caller's details and tags back to the GoHighLevel contact. It replaces Missed Call Text Back with a conversation that finishes the job.
Why Missed Call Text Back is no longer enough
Missed Call Text Back was the first automation most GoHighLevel agencies sold: a text goes out when a call is missed, and some callers reply. It saves a share of leads but it moves the work back to the business, which now has to text with the lead, find a slot and confirm it. An AI receptionist answers the call itself, so the lead never becomes “missed” in the first place.
What the receptionist does on a call
- Answers on the business’s number, or as the fallback when staff do not pick up within a set number of rings.
- Greets with the business name and asks how it can help.
- Answers questions from the knowledge base you build from the client’s website, services and pricing.
- Qualifies with the questions the business would ask, such as service area, urgency or insurance.
- Checks live availability in the GoHighLevel calendar and offers slots.
- Books, reschedules or cancels the appointment in the calendar during the call.
- Extracts details such as name, phone, email and address into the contact’s fields.
- Tags the contact, for example “qualified” or “customer support”, so pipelines and workflows fire.
- Transfers live to a human when the caller asks for a person or the call needs one.
- Follows up by SMS or email after the call if the caller did not book.
Setup inside GoHighLevel
Assistantz.ai runs the receptionist and GoHighLevel remains the system of record. The sequence, which the onboarding knowledge base walks through:
- Connect Assistantz.ai to the sub-account from the GHL App Marketplace.
- Create the assistant; the AI writes the prompt from the business’s website. Edit tone and rules if needed.
- Buy a number inside Assistantz.ai or import the client’s existing Twilio number.
- Deploy the inbound call assistant, then add two GoHighLevel workflows for the inbound webhook and the post-call transcript.
- Set the calendar the assistant books into and activate it.
- Test by calling the number from your phone.
Most agencies complete this in under an hour for a new client.
What the client sees
Everything lands in their GoHighLevel conversation view and calendar under your agency’s branding: the call recording and transcript, the appointment, the updated contact and the tags. The Assistantz.ai dashboard, if you give the client access, carries your logo, colours and domain.
