    I want to replace a traditional receptionist with an AI-driven solution that can both answer incoming calls and automatically return any missed calls on my South African business line. Callers must be able to speak naturally or use their phone keypad, and the system should respond on its own without having to hand the call to a human operator. Here is what I need built and handed over: • A cloud or on-prem setup that connects to my existing South African number, answers 24/7 and places callback attempts when we miss a call. • Conversational logic that recognises voice and DTMF input, then speaks back clearly—preferably through a flexible text-to-speech engine so I can update scripts myself. • Secure storage of call recordings, transcripts and basic analytics so ...

    I want to deploy a voice agent that can answer and place phone calls just like a live rep, gathering the caller’s details, understanding the intent of the request, and supplying clear answers in real time. The primary goal is customer support, so every part of the flow—from the greeting to the wrap-up—should feel helpful, polite, and human. Core expectations • Natural-sounding speech recognition and TTS • Intent detection for common support questions, with an easy way for me to extend the dialog later • Ability to handle both inbound and outbound calls on the same number • Real-time call logging plus a transcript or audio archive I can download • Webhook or REST hooks so I can tie the conversation data into my CRM when I’m ready Deliverabl...

    I’m planning an Android-only chat product whose sole purpose is secure, high-quality voice calling. Before I start coding, I want an experienced real-time communications engineer to walk me through the best technical approach and help me avoid common pitfalls. In a single consultation session (up to 90 minutes) followed by a short written brief, I’d like you to cover: • The overall call flow: signalling, NAT traversal, TURN/STUN servers, and how everything fits together on Android. • Which SDKs or libraries (e.g., WebRTC, liblinphone, or other proven stacks) make the most sense for voice-only traffic. • A step-by-step blueprint for implementing true end-to-end encryption on the audio stream—key exchange, SRTP, Double Ratchet or similar—and how t...

    I need hands-on help finalising the configuration of our Linux-based industrial gateways that sit on board commercial vessels. The gateways are already built into our monitoring platform; the job is about tightening up their field readiness rather than starting anything from scratch. The immediate milestone is remote commissioning. Over the next four weeks I want each new unit to boot, establish a secure MQTT link, pull its TLS certs, and start streaming CAN/J1939 and NMEA data to our cloud broker without manual intervention. If you have brought similar hardware online before, you know how valuable clear-cut configs and repeatable scripts are to installers working at sea. Key areas we will tackle together • MQTT broker connection details, authentication and automated cert renewal ...

    I am building a conversational AI that can serve customers through voice, not just text. The assistant must act as a full-service front line, able to: • Answer our most common FAQs with friendly, accurate responses • Handle complaints empathetically and log them with proper categorisation and escalation tags • Guide callers through order placement, status checks, and basic modifications, then push the data into our existing order-management API Fluency in both English and key Indian languages is essential so every caller receives the same high-quality experience. Natural, human-sounding speech synthesis and rapid intent recognition are priorities; dead air or obvious “bot pauses” are deal-breakers. I will supply current FAQ content, complaint workflows, ...

    AI-Powered IVR to Empirix Hammer Script Automation I am looking for an experienced automation developer to build a tool that can convert manual IVR call recordings into automated Empirix Hammer test scripts. Currently, I test Google Dialogflow CX conversational IVR systems by making manual calls, verifying responses, and then manually creating test scripts in Empirix Hammer On-Demand QA. My goal is to automate this script creation process as much as possible. Project Requirements 1. Accept a complete manual IVR call recording or transcript as input. 2. Identify the IVR prompts and caller responses separately. 3. Detect caller voice inputs, DTMF presses, and pauses. 4. Convert the conversation into corresponding Empirix Hammer actions, including: * Place Call * Hear Voice * S...

    I have a Cisco UC540 on-site and a live SIP trunk supplied directly by our ISP. All the registration details—SIP username, password, registrar, codecs, DID ranges—are already in hand; what I need is a specialist who can jump in remotely, register that trunk on the UC540 and make sure both inbound and outbound calls flow cleanly. Here is how I picture the engagement: • Remote configuration through CCA or pure CLI, whichever you are most efficient with. • Correct dial-peers, voice class codecs and translation rules so our full DID block reaches the right ephone-DNs and outbound calls present the main number. • Basic feature verification: two-way audio, multiple simultaneous calls, caller-ID, and voicemail routing to CUE. • A brief hand-over showing the...
