CallVIQ V2.1 – Autonomous AI Voice Calling, Visual Node Flow Builder, Prompt-to-Flow AI, WhatsApp Automation, Multi-App Workflow SaaS (Node.js, Next.js)

CallVIQ V2.1 is a self-hosted, enterprise-grade multi-tenant Voice AI SaaS and autonomous telephony platform built for agencies, businesses, call centers, and SaaS entrepreneurs. It replaces traditional, expensive human call desks with human-grade, ultra-low-latency Voice AI agents capable of handling inbound reception, automated outbound cold calling, dynamic CRM lead qualification, appointment booking with Google Calendar/Meet, WhatsApp messaging, and multi-app workflow automations around the clock. Buyers install it on their own server, white-label it completely, and launch their own branded Voice AI SaaS business in minutes.

3 Flexible Operational Business Models: CallVIQ V2.1 offers unmatched flexibility for platform owners with three configurable operating models:

1. Master Managed Fixed Model: The platform owner supplies master platform API keys in the Super Admin panel and assigns fixed default AI LLM and Voice synthesis models (e.g., Gemini 2.0 Flash + ElevenLabs). Tenants enjoy a seamless zero-configuration experience, and token/character usage is automatically metered and billed to their workspace wallets.
2. Master User-Selectable Model: The platform owner provides master platform API keys and curates a roster of allowed AI LLM and Voice models. Tenants can freely select their preferred AI model from the enabled roster without entering their own API keys.
3. Bring Your Own Key (BYOK) Model: Tenants connect their own personal API keys across Twilio, Telnyx, OpenAI, Gemini, ElevenLabs, etc. The platform host incurs zero third-party API costs.

Powerful V2.1 Additions:

Prompt-to-Flow AI Generator: Simply type a natural language prompt describing your business or calling scenario, and the AI automatically builds, configures, and connects the entire interactive visual node graph in seconds.
Integrated WhatsApp Automation: Automatically send booking confirmations, meeting links, or brochures to callers via WhatsApp during or after calls using either the Baileys QR Code Engine (direct phone pairing) or the Official Meta Cloud API.
Workflow Automation (Zapier, n8n, Make and Webhooks): Connect external apps and workflows seamlessly with real-time lifecycle event webhooks (call.completed, lead.qualified, appointment.booked) and trigger automated outbound AI phone calls dynamically from external web forms, lead ads, or CRM pipelines.

CallVIQ V2.1 — Autonomous Multi-Model Voice AI Platform with Visual Node Builder, Prompt-to-Flow AI, WhatsApp Automation and Multi-App Workflow Integrations

CallVIQ V2.1 is an enterprise-grade, multi-tenant Voice AI SaaS and autonomous telephony platform. It enables businesses, call centers, and agencies to deploy human-grade, ultra-low-latency Voice AI agents capable of handling inbound reception, automated outbound cold calling, dynamic CRM lead qualification, appointment booking, WhatsApp messaging, and multi-app workflow automations at scale.

Super Admin Panel and Platform Architecture

The Super Admin console provides complete administrative, operational, and financial control over the entire platform. Platform owners can create and manage tenant accounts manually or via automated email invitations, adjust wallet credits, override concurrency limits, suspend, reactivate, or soft-delete tenants, and impersonate any tenant workspace with a single click for instantaneous support and onboarding assistance.

Dynamic Subscription Plans and Stripe Sync: Build tiered subscription plans directly from the UI with custom pricing, monthly call minute allowances, AI token allocations, concurrency limits, and granular feature flags (Inbound Call Routing, CRM Integrations, Call Recording, WhatsApp Automation, and Workflow Webhooks). Plans automatically synchronize products and pricing with Stripe.

3 Flexible AI and Voice Operational Models:

1. Master Managed Fixed Model: The platform owner configures master platform API keys in the Super Admin panel and assigns fixed default LLM and Voice engines (e.g., Google Gemini 2.0 Flash + ElevenLabs). Tenants enjoy a zero-configuration experience, and token/character usage is automatically metered and billed to their workspace wallets.
2. Master User-Selectable Model: The platform owner supplies master API keys and enables a curated roster of allowed LLM models and Voice engines. Tenants can freely select their preferred AI model from the enabled roster without entering their own API keys.
3. BYOK Model (Bring Your Own Key): Tenants supply their own encrypted API keys for LLMs and Voice synthesis providers in their workspace settings.

Platform Settings and White-Label Branding: Full white-label customization including platform name, logo, favicon, custom color palettes, support email, social links, and SMTP / Resend mailer configuration. The built-in legal page editor manages Terms of Service, Privacy Policy, DNC compliance guidelines, and system notification banners served dynamically to the application.

Analytics and Infrastructure Health: Real-time financial and telemetry dashboards tracking Monthly Recurring Revenue (MRR), Annual Recurring Revenue (ARR), active subscriber growth, total call minutes, token throughput, and credit ledger operations. The infrastructure monitor displays live CPU, RAM, disk usage, MySQL connection pool stats, Redis BullMQ queue depths, and third-party API latency with one-click failed job retry and purge capabilities.

4-Tier RBAC Security: Enforces granular role-based access control (Owner, Administrator, Support Agent, Viewer) with safety locks that prevent owner orphan states, unauthorized privilege escalation, and full TOTP two-factor authentication (2FA).

Tenant Dashboard and Voice AI Workspace

Tenants are guided through an interactive multi-step onboarding wizard covering business profile setup, plan tier selection, telephony provider hookup (Twilio, Telnyx, Plivo, Vonage, or custom SIP), and AI model configuration. All API keys and secrets are encrypted at rest using AES-256-GCM.

Visual Drag-and-Drop Node Flow Builder: Build complex, interactive voice conversation trees using an intuitive visual node canvas. Supported node types include:

Greeting Node: Initial conversational greeting with dynamic template variables.
Question and Collect Info Node: Natural language questions with structured entity and variable extraction.
Condition and Sentiment Branching Node: Smart classification of customer intent, affirmative/negative answers, and emotional sentiment.
Menu / DTMF Keypad Node: Interactive voice response (IVR) menu with digit keypad detection.
Knowledge Retrieval (RAG) Node: Grounded FAQ lookup querying uploaded documents, PDFs, and crawled URLs.
Book Appointment Node: Calendar-aware scheduling with Google Calendar sync, conflict prevention, and Google Meet link generation.
Send WhatsApp Node: Automated dispatch of confirmation messages, brochures, or booking links to the caller’s WhatsApp.
Play Audio Node: Seamless playback of custom audio recordings, hold music, or pre-recorded prompts.
Transfer to Human Node: Live call handoff and warm transfer to human agents or support hotlines.
End Call Node: Polite farewell and clean call termination.

Prompt-to-Flow AI Generator: Transform natural language descriptions into complete, fully connected node graphs. Simply describe the conversation scenario (e.g., “Create an appointment booking and FAQ bot for a dental clinic”), and the AI automatically generates all conversation steps, variables, and decision branches in seconds.

WhatsApp Automation Engine: Built-in multi-channel WhatsApp messaging with two operational options:

Baileys QR Code Engine: Scan a QR code directly from WhatsApp on your mobile phone to connect and send messages from your personal or business WhatsApp number without Meta approval delays.
Official Meta Cloud API: Connect Meta Business Account access tokens and Phone Number IDs for enterprise-scale automated messaging.

Workflow Automation (Zapier, n8n, Make and Webhooks):

Outbound Lifecycle Webhooks: Transmit real-time event payloads (call.started, call.completed, call.analyzed, lead.qualified, appointment.booked) to Zapier, n8n, Make.com, or custom API endpoints.
Inbound Trigger Webhooks: Trigger automated outbound AI phone calls dynamically from external web forms, lead generation ads, or CRM pipelines.

Campaign Manager: Supports five campaign formats: Outbound Blast, Drip Sequence, Event-Triggered, Inbound Dynamic Routing, and Appointment Reminders. Features smart caller ID rotation, calling-hour window enforcement, timezone detection, retry policies, call frequency limits, and automated credit depletion safety pauses.

Live Call Monitor: Streams active calls in real time via WebSocket push updates. Supervisors can monitor live audio status or terminate calls directly from the dashboard. Post-call processing generates diarized transcripts, AI summaries, sentiment scores (positive, neutral, negative), outcome tags, and lead scores (0 to 100).

CRM and Lead Pipeline: Comprehensive contact manager with custom fields, tag-based segmentation, and a Kanban lead pipeline with drag-and-drop status stages. Contact lists support high-speed CSV imports of up to 100,000 rows with column mapping and duplicate resolution rules.

In-Browser Testing Playground: Interactive call simulator with visual audio waveforms, live speech-to-text response previews, template variable injection, and Voice Activity Detection (VAD) for testing agents before launching live campaigns.

Support Desk: Built-in ticketing module allowing tenants to create support requests (Billing, Telephony, Technical, General) with priority tags, file attachments, and threaded admin communication.

Real-Time Calling Engine and Telephony Layer

CallVIQ V2.1 operates a low-latency telephony pipeline built on bidirectional WebSockets (wss://). When a call connects, BullMQ pops contacts from the dialing queue, initiates outbound calls via cloud telephony REST APIs, and connects a real-time WebSocket audio bridge streaming raw base64-encoded μ-law audio chunks (8kHz) directly to the backend.

Supported Telephony Providers:

Twilio: Twilio Voice REST API + Twilio Media Streams audio WebSocket.
Telnyx: Telnyx Voice API + TeXML / Call Control WebSocket streams.
Plivo: Plivo Voice API + Stream XML bidirectional audio channel.
Vonage (Nexmo): Vonage Voice API + NCCO WebSocket audio streams.
Custom SIP Trunking: Generic SIP trunks (Asterisk, FreePBX, Kamailio, OpenSIPS) for direct PBX integration.

The engine features sub-second barge-in interruption handling (voice activity detection halts bot audio immediately when the caller speaks), silence detection with intelligent follow-up prompts, and automated post-call job dispatching.

AI and LLM Orchestration Layer

CallVIQ V2.1 dynamically routes conversation prompts through a multi-provider LLM orchestration engine supporting 9 industry-leading AI providers:

Google Gemini: Gemini 2.0 Flash (ultra-fast latency), Gemini 1.5 Pro, and Gemini 1.5 Flash.
OpenAI / ChatGPT: GPT-4o, GPT-4o Mini, o3-mini (reasoning model), and GPT-4 Turbo.
Anthropic Claude: Claude 3.5 Sonnet, Claude 3.5 Haiku (conversational model), and Claude 3 Opus.
Groq LPU Engine: Llama 3.3 70B Versatile and Llama 3.1 8B Instant (ultra-fast LPU inference).
Mistral AI: Mistral Large Latest and Open-Mixtral 8×22B.

Voice and Speech Synthesis Engine

CallVIQ V2.1 streams text-to-speech audio synthesis across 9 voice providers:

ElevenLabs: High-fidelity audio synthesis using eleven_turbo_v2_5 with stability and similarity controls. Includes American voice presets (Rachel, Domi, Bella, Antoni, Adam, Nicole), Indian accent presets (Ananya, Rohan, Kavya, Aarav, Aditi, Dev), and Multilingual presets (Clyde, Dave, Freya, Giovanni).
Cartesia AI: Ultra-low latency streaming TTS using the sonic-english model (voices: Blake, Jessica, Chloe, Austin).
OpenAI Voice: Low-latency tts-1 engine (voices: alloy, echo, fable, onyx, nova, shimmer).
Microsoft Azure Cognitive Services: Neural speech engine (default: en-US-JennyNeural).
Deepgram Aura TTS: Low-latency neural TTS (default: aura-asteria-en) + Deepgram Nova STT.

Microsoft Edge Free TTS: Built-in zero-cost fallback speech engine (default: en-US-AvaNeural).
Vapi Voice Agent Gateway: Proxied end-to-end voice-agent wrapper for direct telephony proxying.

Google Workspace and Enterprise CRM Integration Hub

Google Workspace Integration: Connect Google accounts to enable calendar-aware appointment scheduling. The voice bot queries real-time slot availability across staff Google Calendars, avoids double bookings, and creates Google Calendar events complete with location details and Google Meet video links. Google Sheets integration enables automated two-way contact synchronization.

Enterprise CRM Connectors: Native two-way integrations with HubSpot CRM, Salesforce Cloud, and Zoho CRM. Incoming caller phone numbers are mapped to CRM contacts in real time, and call outcomes, diarized transcripts, and AI summaries are synced directly to CRM contact timelines.

Billing, Wallet and Credit Metering

Integrated with Stripe for automated subscription lifecycle management and credit top-ups. Tenants can manage payment methods, upgrade plans with proration, download invoices, and configure auto-recharge thresholds. Real-time token and character metering logs every call’s AI and voice consumption to ai_usage_logs. Credits are managed via Redis atomic operations to prevent balance race conditions.

Security, Privacy and Compliance

All tenant API credentials (Twilio SIDs, Telnyx keys, Plivo tokens, Vonage secrets, SIP passwords, OpenAI/Gemini/Anthropic keys, ElevenLabs keys, and OAuth tokens) are encrypted at rest using AES-256-GCM. Includes GDPR compliance tools (complete data export package in JSON format and permanent account deletion purge). Outbound calling automatically enforces calling hour windows, call frequency limits, recording consent playback, and global/tenant DNC list screening.
