FAQs

Do I need phone hardware?
No. Most voice tools connect over API or cloud telephony. They pass data to GHL via webhook, Zapier or custom integration.

Can I track agent results in GHL?
Yes. Log call result, time, or transcript into GHL’s contact record and trigger workflows from there.

Which tool is best for beginners?
Zapier and ElevenLabs require no coding. Vapi and LangChain require dev skills.

Will AI voice calls save time?
Yes, if configured well. The AI agent handles replies, follow-ups and routing for you, so manual calls are reduced.
