We are building a structured AI-powered call routing system in South Africa. The system must: • Integrate with existing PBX systems via call forwarding or SIP • Use a South African virtual number • Route inbound calls through an AI voice receptionist • Identify query type • Provide structured information • Escalate security-related matters • Send SMS notifications when required • Log call analytics This is NOT a chatbot project. This is a voice AI + VoIP routing infrastructure project. Technical Requirements: Developer must have experience with: • SIP / VoIP integration • PBX systems (3CX, Yeastar, Telkom, etc.) • Twilio or similar telephony APIs • AI voice agent implementation • Call forwarding configuration • SMS API integration • Cloud deployment Experience with South African telephony providers is a major advantage. Scope of Work: Phase 1: • Configure virtual SA number • Implement AI voice routing • Build structured call flow logic • Configure escalation paths • Implement SMS/email notification system Phase 2 (optional expansion): • Tenant overflow routing • WhatsApp integration • Dashboard analytics Project Type: Fixed Price or Milestone-Based (open to proposals) Important: Please provide: • Examples of similar VoIP/AI projects • Experience with PBX integrations • Telephony providers you’ve worked with • Estimated timeline You will be required to sign a NDA and Non compete Agreement upon speaking about the project after bidding.
