Works with the tools you already use
Everything Your Business Needs
Manage business calls, robocalls, WhatsApp, Telegram, AI agents, and customer conversations from a single platform.
Browser-Based Web Dialer
Make and receive calls directly from your browser without installing additional software.
Smart IVR & Call Queues
Route callers to the right department with professional IVR menus and intelligent queue management.
Live Call Monitoring
Monitor active calls for training and quality assurance. Listen, barge in, or terminate calls in real time.
Call Recording
Record inbound and outbound calls for quality assurance, compliance, and team training.
Auto Campaigns
Automatically create and run campaigns based on predefined rules, triggers, and customer interactions.
Time-Based Call Routing
Automatically route calls based on office hours, weekends, holidays, or custom schedules.
AI Data Extraction
Automatically captures customer details from calls and updates records, eliminating manual entry and saving time.
Fully Customizable Platform
Customize features, reports, workflows, and integrations to match your business requirements.
Role-Based Access Control
Assign permissions for administrators, supervisors, and agents with granular access controls.
WhatsApp Business Calling — your flagship channel
Customers tap Call inside WhatsApp and land in your IVR, queue, agent, or AI bot. Agents click to call back — their extension rings first, then the customer's WhatsApp.
Inbound and outbound WhatsApp calls follow the same dialplan as your voice lines — queues, IVRs, time conditions, AI bots and voicemail all work. The permission flow is handled automatically and respects Meta's 24-hour customer-service window, so in-window calls dial straight through.
Audio is HD Opus at 48kHz over WhatsApp data — no carrier minutes, and typically 60–80% cheaper than traditional voice. It runs on the official WhatsApp Cloud API with per-tenant credentials, not a grey-market gateway.
AI that works the phones and the chats
Two voice engines, instant chat auto-reply, and AI that can even take and submit orders.
Realtime voice bot
Natural, sub-second phone conversations that answer, qualify and route — and hand off to a human the moment it hits a limit.
Knowledge-grounded smart bot
A RAG bot answers from your uploaded PDFs and docs across voice and chat — transcribing incoming WhatsApp/Telegram voice notes and replying automatically.
AI that takes orders
Collect an order in conversation, build a structured JSON order and POST it to your POS, CRM or kitchen — every order logged, tracked and one-click resendable.
Bring your own keys — OpenAI, Deepgram, Google, Azure, ElevenLabs, Anthropic & Groq. Pick a model per bot or channel.
