Construction AI Call & Text Assistant

My construction-remodeling firm needs an AI agent that can speak naturally, text convincingly, and email professionally while tying everything together inside n8n. I already use ElevenLabs for lifelike voice, so the call flow must leverage its TTS / voice-cloning and feed straight into n8n automations.

Core scope
• Inbound calls: greet callers, answer basic service questions, capture lead details and, when asked, book or reschedule an appointment in our calendar system.
• Follow-up outreach: automatic SMS and email sequences that go out after the first conversation, plus the ability to place an outbound call if a prospect hasn’t replied.
• Multichannel syncing: every interaction—phone, text or email—should update the same contact record so my team always sees the latest status.
• Query handling: appointment scheduling, general service inquiries and routine customer-support questions. Escalate anything complex to a live rep.

Tech requirements
• ElevenLabs for voice synthesis.
• n8n as the workflow engine so I can tweak logic later without code.
• Clean REST or webhook connections to our existing CRM (HubSpot) and calendar. If you prefer Twilio or a similar gateway for telephony/SMS, that’s fine—just wire it neatly into n8n.

Acceptance criteria
1. I can pick up the phone, speak to the agent and receive a realistic, on-brand voice response.
2. After hanging up, I get an SMS and an email that pull the correct merge fields.
3. All data points appear in the CRM contact timeline within one minute.
4. Your documentation shows me where to adjust prompts, timing, and message copy.

Hand-over items: exported n8n workflow JSON, ElevenLabs voice profile settings, any custom scripts, and a short Loom walkthrough.

If you have built similar multichannel agents before, let me see a quick demo or outline of your approach so we can get started right away.
