I am seeking a developer to create a cloud-based AI receptionist system for my medical office in Greece. The system should handle inbound and outbound calls in Greek, record and transcribe conversations, and send email notifications with caller details. It must be based primarily on open-source technologies to minimize ongoing costs, self-hosted on a VPS, and GDPR-compliant. Key features include speech-to-text transcription, text-to-speech responses, email integration, and compatibility with my existing phone line via SIP trunk or FXO gateway. The ideal freelancer should have experience with Asterisk/FreePBX/VoIP systems, speech recognition (Vosk), TTS systems (Piper), Python scripting, and AI-assisted telephony. Deliverables: - Fully functional inbound/outbound call system with web interface. - Configured STT, TTS, and AI modules (Greek language). - Email notification automation. - Cloud VPS setup with documentation. - One live test call confirming end-to-end functionality.
