I will connect your sip trunk or phone number to an ai voice agent


Level 2
About this gig
Want a phone number that answers itself? A real AI voice agent that talks to your customers, qualifies leads, and books appointments 24/7.
I connect your SIP trunk or phone number (Telnyx, Twilio, Vonage, or any provider) to an AI voice agent built on Asterisk/FreePBX and the best AI engines -
Deepgram, ElevenLabs, OpenAI and Gemini. Not a fragile no-code demo: production telephony that handles real calls.
What you get:
- Inbound and/or outbound AI calling
- Natural voice (ElevenLabs) + accurate speech-to-text (Deepgram)
- Smart call flows: answer, qualify, route, book
- CRM integration (Odoo, Zendesk, Salesforce, HubSpot)
- Clean handover to a human when needed
Why me: 16+ years in VoIP/SIP and large-scale voice platforms, AWS Solutions Architect Professional, with a multi-tenant PBX platform already running in
production.
Need it hosted and maintained? Add managed hosting and I'll keep it running for you.
Message me before ordering with your use case and provider, and I'll map the fastest path and the exact package for you.
