    I want to put an always-on AI voice agent in charge of one thing only: generating brand-new cold leads by telephone. I will provide the target market, ideal-customer profile, and high-level talking points; you build, train, and deploy the agent so it can dial prospects, hold a natural conversation, qualify interest, and pass every promising contact straight into my CRM. The agent must: • sound human and handle common objections in real time • record, transcribe, and store every call • schedule callbacks or meetings on my calendar • respect local calling regulations (TCPA, GDPR where applicable) I’m comfortable with Twilio Voice, Dialogflow, ElevenLabs, GPT-4, or any similar stack—as long as call quality and scalability stay top-tier. Show me a short archit...

    I need an experienced telephony engineer to bring up a new IVR on our Asterisk-based server that will answer calls coming in on both a SIP trunk and a PRI.

Environment • Linux box already running Asterisk (remote SSH available) • One SIP trunk + one PRI (credentials and circuit details ready) Scope of work 1. Configure the IVR in Asterisk, activate call routing options, and confirm that both trunks follow the same logic. 2.

    I need a working proof-of-concept Voice Agent CRM whose entire logic runs on an n8n instance that I host. The system’s core goal is customer support, so the voice agent must effortlessly answer FAQs, open or update tickets, and, when necessary, transfer a live call to a human agent. Key expectations • n8n will orchestrate every step—speech-to-text, intent detection, CRM updates, and call routing—so the workflows you build have to be easily readable and fully documented inside the editor. • Scheduling flows should connect to Google Calendar; if you can keep the design flexible enough to plug in Outlook or Apple Calendar later, even better. • Tickets can live in a lightweight built-in board, a fresh Postgres table, or a customary help-desk SaaS as lo...

Als Herzstück soll ein Asterisk-Server laufen, den wir in unserer eigenen Infrastruktur betreiben. Rund 11 – 50 Mitarbeitende werden die neue Anlage täglich nutzen. Folgende Kernfunktionen sind zwingend erforderlich: • Anrufweiterleitung • Voicemail • Konferenzschaltung Alle bestehenden Rufnummern sollen nahtlos portiert und auf der neuen Plattform weitergeführt werden. Neben der eigentlichen Installation erwarte ich eine kurze Dokumentation der Systemarchitektur, eine verständliche Anleitung für zukünftige Erweiterungen sowie einen Testlauf, bei dem alle Funktionen live verifiziert werden.
