AI voice agents
AI voice operations for modern teams
The operating system for AI voice agents.
Unlike voice AI platforms that only provide an agent, CallKernel gives you the complete operational layer—campaigns, calendars, reservations, transfers, billing, logs, and telephony—in one dashboard.

Real-time call loop
A visual operating layer for what happens during the call.
The caller talks to a real-time AI voice agent, the agent uses approved tools, and the dashboard records the outcome your team needs after the call.

Platform
The complete workflow around every call.
An AI voice agent can talk. CallKernel helps a business operate calls with scripts, knowledge, calendars, campaigns, tables, workers, extensions, invoices, and diagnostics.
Script setup
Business-specific call behavior
Separate knowledge and script profiles for appointment businesses and restaurant-style table reservations, with compact prompts for real-time voice.Calendar and resources
Appointments, workers, tables, and walk-ins
Run worker calendars for barbers or doctors, or switch to restaurant mode with table capacity, blocks, seated status, and reservation changes.Outbound campaigns
Dialer operations with follow-through
Upload contacts, place test calls, pace campaigns, schedule callbacks, capture dispositions, and extract structured info from transcripts.Observability
Know what happened on every call
Monitor live calls, latency, transcripts, runtime cost, recordings, usage, webhook events, billing status, and integration health.Telephony
Built for real phone infrastructure
Connect Asterisk ARI, SIP endpoints, extension blocks, human transfer pools, Linphone tests, and dashboard-controlled outbound origination.Inbound
Answer, book, reserve, and transfer without losing the caller.
Use worker mode for appointment businesses or restaurant mode for table reservations, walk-ins, blocks, and status changes.

Restaurant mode
A reservation board built for tables, walk-ins, blocks, and status changes.
Restaurant deployments need a host-style view, not a generic appointment calendar. CallKernel models each table as a reservable resource with capacity and state.

FAQ
Questions teams ask before launching an AI voice agent.
Is CallKernel only a voice bot?
No. The AI voice agent is one part of the system. The dashboard also manages scripts, knowledge, calendars, campaigns, billing, contacts, extensions, logs, and compliance controls.
Can it handle restaurant reservations?
Yes. Restaurant mode uses tables as bookable resources with capacity, reservations, walk-ins, timed blocks, seated/completed/no-show states, and a reservation board.
Can humans still answer calls?
Yes. CallKernel supports human transfer prompts and dashboard-managed extension pools so callers can be routed to available staff when needed.
Does it support outbound campaigns?
Yes. Campaigns can use contact lists, pacing, retries, callbacks, dispositions, DNC controls, and transcript-based data extraction.
Do you provide setup help?
Yes. For early deployments we help map the first flow, configure telephony, load scripts and knowledge, and test calls end to end.
