## Self-Service Management & Telephony
You can manage a KaiCalls agent four ways — voice, dashboard, REST API, and AI assistant (MCP). The voice channel is first-class: owners change settings and run their business by phone, not just in the dashboard.
- [Call Kai (voice admin)](https://www.kaicalls.com/help/admin-secretary): Call your agent's own number from a registered admin phone and ask in plain language — "what calls came in?", "change my greeting", "we're closed Sundays now", "text John back", "book Tuesday at 2", "undo that". The secretary can read your stats/leads/voicemails and update greeting, prompt, voice, hours, services, knowledge, booking links, and ring-first numbers, then roll changes back.
- [Dashboard](https://www.kaicalls.com/dashboard): Full web interface for the same settings, plus leads, calls, SMS, analytics, and integrations.
- [REST API](https://www.kaicalls.com/docs/api): Programmatic management — agents (create/patch prompt, voice, model), calls, leads, SMS, communication runs (outbound), webhooks. Bearer keys (kc_live_) with scopes.
- [Connect Claude, ChatGPT, Grok, or Manus (MCP)](https://www.kaicalls.com/help/ai-assistant): Connect an AI assistant to your account so you can ask it to read calls/leads/voicemails/analytics and request agent changes in chat. ChatGPT users can install the published KaiCalls app from the ChatGPT app directory; every other MCP client adds https://www.kaicalls.com/api/mcp as a custom connector. Per-client setup (Claude, ChatGPT, Grok, Manus, Gemini, Cursor, VS Code, Claude Code, Codex, and more): [AI connectors guide](https://www.kaicalls.com/docs/api/connectors).

## PBX & DNI Telephony Capabilities
- **Native PBX Integration**: Physical SIP desk phones, hunt groups, ring groups, simultaneous ring, attended/blind transfers, and automated AI overflow handling.
- **Dynamic Number Insertion (DNI)**: Dynamic phone number pool tracking and visitor session attribution bridging web traffic (Google Ads GCLID, Meta CAPI, GA4, AI search engines) to inbound calls and Stripe MRR conversions.
- **AI Referral Attribution**: First-class tracking for AI search engines and assistants (ChatGPT search/plugin/ads, Claude, Perplexity, Grok, Microsoft Copilot).

## What You Can Ask an AI Assistant
Once the MCP connector is attached, these are the jobs owners use it for. Each example is a real request the connector can carry out on a connected account.
### Catch up on what you missed
The morning question, without opening the dashboard or listening to anything.
- "Did I miss anything overnight?" — Reads back last night’s calls, voicemails, and texts in one answer.
- "Summarize the calls Kai handled this week and how many turned into leads." — Totals for the week, with the calls that produced a lead called out.
### Fix how Kai talks
When a caller got the wrong answer and you want it never to happen again.
- "Kai keeps flubbing the pricing question. Pull a recent call and fix it." — Finds the call, reads the transcript, and updates the agent so it answers right.
- "We’re closed Sundays now." — Updates your hours so Kai stops offering Sunday appointments.
- "Add our $149 drain-cleaning special so Kai quotes it correctly." — Adds the offer to what Kai knows, so it can quote the price on a call.
### Chase leads and follow up
Have Kai place the calls and send the texts you would otherwise do yourself.
- "Call the three leads from yesterday who never booked." — Kai places the calls and reports back how each one went.
- "Text the customer from the 2pm call our address and a booking link." — Sends the text from your business number.
### Test before you trust it
Run the voice tests against your own line — the same regression pack, on demand, in a sentence.
- "Test that the after-hours flow still works before I go to bed." — Runs your saved call scenarios and tells you which ones passed.
- "I just changed the greeting — re-run the tests and tell me if I broke anything." — Re-runs the scenarios against the current setup and reports failures.
### See what changed, and undo it
Every change is recorded, so "put it back how it was" is a real instruction.
- "What changed on my agent last week, and who changed it?" — Lists the changes with timestamps and where each one came from.
- "Undo whatever changed the greeting last Tuesday." — Rolls that change back and confirms what the greeting says now.
### Check usage and billing
Answer "am I about to get a surprise?" without a support ticket.
- "Am I going to blow past my plan this month?" — Compares answered calls against your allowance and flags a better-fitting plan.
- "Why did my bill change?" — Walks through the plan and add-on changes on your account.
### Check nothing is quietly broken
Catch a dead calendar or CRM connection before a customer finds it for you.
- "Is anything broken today?" — Surfaces failed bookings, sync errors, and tool timeouts from your calls.
- "Is my number actually answering right now?" — Confirms which numbers are live and attached to which agent.
