My Portfolio
FAQ
Can the AI voice agent integrate directly with GoHighLevel (GHL)?
Yes! The AI agent can automatically update contact records, create pipeline opportunities, add custom tags, trigger follow-up SMS workflows, and update custom CRM fields immediately after a call finishes.
How does the AI agent book appointments without double-booking?
The AI agent connects directly to your calendar (GoHighLevel, Google Calendar, or Calendly) via real-time API integrations. It reads live availability slots, confirms the date/time with the caller, and books the appointment instantly during the conversation.
Will the AI voice agent sound robotic or have noticeable lag/latency?
No. By utilizing optimized LLM prompting, efficient Webhook routing, and ultra-fast text-to-speech providers like ElevenLabs, we achieve sub-second response latency. The agent handles interjections, pauses naturally, and sounds completely human
Do I need extra subscriptions to run the AI voice agent?
Yes, you will need your own accounts for the essential platforms (such as Vapi or Retell AI, Twilio or Phone numbers, and GoHighLevel). You only pay for what you use, and I will assist you in setting up the correct API keys and accounts during kickoff
Can the AI voice agent make outbound cold calls?
Absolutely! We can configure outbound speed-to-lead agents that call new leads within seconds of form submissions, or set up automated batch campaigns to qualify cold leads and book meetings.
What do I need to provide to get started?
Your call script or target conversation outline. Temporary API access to your Vapi/Retell, Twilio, and GoHighLevel accounts
