    I’m building a voice-driven receptionist that greets visitors or callers, listens to their questions, and replies with a natural-sounding voice. The core flow is straightforward: • Speech-to-text: Accurate recognition of English only is required for now. • NLP: Classify the intent and pull the correct answer when a caller asks about our business hours or location. • Text-to-speech: Respond with friendly, human-like audio. • Fallback: whenever the system is unsure, it should politely ask for more details rather than handing the call off or giving a canned line. I need the full stack—STT, intent handling, response generation, and audio playback—wrapped in a module that I can drop into my existing website widget today and expand to a phone line ...

    I need a streamlined website whose sole function is to host and manage a voice-based AI call-center. The site will act as the control panel and public-facing entry point for customers who dial in, while giving me an admin area to configure and monitor activity. Core requirements • Automated responses: callers must hear natural-sounding, AI-generated answers that pull from a knowledge base I can update myself. • Live call routing: when the AI decides human help is needed, it should hand the caller off to a live agent instantly and log the transfer. • Voice channel only: chat or email may be added later, but right now the system must excel at telephone interactions. Technical expectations – Cloud telephony integration (Twilio, Plivo, or similar) for SIP/VoIP ha...

    I need a fully-functional Google Voice account for 10 Users supported, registered from India but tied to a U.S. phone number, so I can place and receive personal calls to and from the States. The account itself does not yet exist and I have not picked a number, so part of the job is guiding me through—or handling—the selection of an available U.S. number that feels natural to me. Because Google Voice is officially unsupported here, you’ll have to take care of the usual hurdles (VPN, verification SMS to a real U.S. mobile, billing profile if required) and then hand over a clean login that I can secure with my own 2-step authentication. I plan to use the service interchangeably on both my smartphone and my laptop, so please configure and test calling on the Google Voice mo...

    I need a dependable professional to handle customer service exclusively over the phone. All calls route through a VoIP system, so you should already be comfortable logging in, managing call queues, and documenting each interaction inside whichever ticketing tool I provide. Accuracy is paramount: every customer request, callback note, and status update must be recorded without errors. Clear, friendly English, an unwavering internet connection, and a quiet workspace are essential for maintaining call quality through VoIP. Your day-to-day will be taking inbound calls, resolving straightforward questions, and escalating anything outside the standard knowledge base once your troubleshooting steps are exhausted. Shift length and schedule are flexible—we will agree on hours that align...

    I already have a Contabo server standing by and simply need a clean, production-ready ViciDial stack on it. The job covers: • Installing the latest stable ViciDial (with Asterisk and its dependencies) from scratch. • Optimising the underlying Linux distro you feel is most reliable for call-centre workloads. • Hardening the box with a well-tested firewall configuration—CSF, UFW, iptables, or a similar solution is fine—as long as only the ports Vicidial, SSH and web administration actually require remain open. • Verifying that the web interface, database, and telephony services all start automatically after a reboot and that calls can be placed through a demo campaign. • Supplying a concise hand-off sheet: all commands run, credentials created, a...

    I’m looking to have a fully-functional AI receptionist built that can pick up every inbound call, hold a natural conversation with the caller, and then route the call to the right person or department purely on the basis of what the caller actually says. The key outcomes I need are: • Advanced conversational AI – the system must go well beyond simple keyword spotting and understand context, intent, and follow-up questions so the interaction feels human. • Dynamic query-based routing – once the caller’s need is clear, the AI should transfer the call to the appropriate extension or external number automatically. • Clean hand-off – when the call is routed, the receiving party must get a short, accurate summary of the caller’s request...

    Vicidial SIP & Campaign Setup

    My Vicidial server is already installed, secured, and reachable from the public internet; what’s missing is the practical know-how to make calls and launch the very first blended (inbound + outbound) campaign. Here is what I need you to walk me through and, where necessary, configure directly on the box: • Register my SIP-trunking provider inside Vicidial, confirm two-way audio, and run a quick live test call. • Create one blended campaign with at least a test list, DID routing for inbound, and the appropriate dial plan entries for outbound. • Show me, via screenshare or concise step-by-step notes, how to add new agents, upload lead lists, record custom greetings, and monitor live calls so I can repeat the process after you leave.

    WebRTC Asterisk TLS Auth Fix
    3 days left
    Verified

    I have a WebRTC soft-phone built with JsSIP that needs to register to an Asterisk 18 server over WSS. SIP credentials are confirmed correct, yet the browser console shows an authentication failure. The signalling path is protected with TLS certificates, so the problem is somewhere in the certificate handling or the way Asterisk presents the challenge. Your job is to trace and eliminate the registration failure, then hand back a clean configuration and proof that the client can successfully register and place a test call. Environment details you will touch: – Asterisk 18 (pjsip stack enabled) – JsSIP running in a standard browser (wss://) – TLS with server and client certificates already issued Acceptance criteria: • JsSIP completes REGISTER without 401/403 r...

    I need a custom panel for my 3CX phone system that listens for DTMF tones during live calls, captures every numerical input the caller enters, and turns those digits into real-time reports I can view instantly in a browser. The key for me is accuracy and speed: as soon as the caller finishes entering a number, the panel should refresh the on-screen report so supervisors can act on the information while the call is still active. I am not looking to store the data long-term or trigger downstream workflows—just fast, on-the-spot visibility of what the caller keyed in. Because everything must sit cleanly inside (or alongside) 3CX, please base your solution on technology that plays well with the 3CX Call Control API, SIP messages, or any proven method you have used before for intercep...

    I’m running my sales operation on Neodove CRM and now want an AI voice agent—functionally similar to Riing AI—to take the first touch on every sales call, then hand qualified prospects over to a live rep. Here’s what I need built: • Seamless link between the voice-bot platform you choose (Riing AI, Twilio Voice + GPT, Dialogflow CX, etc.) and Neodove via API or webhooks so leads, call logs, and dispositions sync both ways. • A sales-focused call flow that greets, qualifies, captures notes, and schedules follow-ups while sounding natural and on-brand. • Real-time warm transfer: when the prospect requests, the bot must instantly pass the call—along with screen-pop details—to one of my human agents. • Clear documentation of every...
