What's inside

Every call, under your control.

A complete calling platform — from the line that routes the call, to the agent that answers, to the update that lands in your CRM.

AI agents for every direction
Enable intelligent agents to handle inbound calls and drive outbound campaigns. ElevenLabs is live today; support for your own stack and Vapi is planned during or after the closed beta. Configure per-direction API keys and agent IDs without touching your dialer.
Multi-account SIP
Register and switch between multiple SIP accounts — different numbers, different servers — without leaving the app.
Automatic recording
Every call captured in AAC, WAV, Opus or OGG. Native playback, scrubbing, and one-click download from anywhere.
Smart call screening
ALLOW, BLOCK, SILENCE — or route the caller to an AI agent. Match by number, prefix, contact, or "anyone not in my contacts". Scope rules globally, per SIP account, or per SIM. Synced in real time.
Transcripts included
Agent-handled calls auto-transcribe. Searchable, exportable, and attached to every call record in the history.
Webhooks, first-class
Fire events on call start, end, save, recording complete, rule change. Primary + secondary endpoints with retry.
Free open-source Android app
Native Android client built with Expo — free, open-source, and yours to fork. Web and iOS clients roll out during beta. One API key, all surfaces.
Encrypted credentials
SIP passwords encrypted at rest. API keys rotated on demand. Rate limits on every request to keep things stable.
How it works

From zero to intelligent dialer in minutes.

No setup required. Install the app, add a SIP account, start dialing.

1
Connect your device
Install the free open-source Android app and paste the API key your service provider issued you.
2
Add a SIP account
One account or many. Your credentials are encrypted at rest. Register, test, and you're ready to dial.
3
Deploy your agents
Turn on inbound or outbound agents per account. Configure webhooks. Let the calls come in.
How Call +AI works

We make the software. Service providers run it.

Call Plus AI builds and maintains the platform. Independent service providers — telcos, resellers, and partners — operate it for their customers. You pick the operator that fits your region, compliance needs, and pricing.

01
Call Plus AI
Software vendor

We build the dialer, the agents, the platform — and ship the free Android client open-source.

02
Service providers
Operate the cloud

Independent operators run the platform for their customers, manage infrastructure, and set their own pricing and SLAs.

03
You
Sign up & dial

Pick the provider that fits, install the free Android app, and you're calling — with agents, recordings, and integrations included.

Call Plus AI doesn't operate phone lines or sell direct to end users. We provide the software, and the same platform can be operated by multiple service providers — so you're not locked into a single vendor.

The product

Designed for people who live on the phone.

Familiar dialer mechanics. Real calling. Everything you need for agents, recordings, screening and webhooks — on the same screen.

Dialer

A dialpad that does more than dial.

Type a number or a name. Matching contacts surface as you type. The account picker puts you on the right SIP line, whether you're calling for sales, support, or the after-hours queue.

  • Live contact matching from device + CRM
  • Account picker — switch line per call
  • Touch tones, hold, transfer, mute, record
  • Deep link from any screen

Agents

Configure agents per line, per direction.

Turn on inbound or outbound agents for each SIP account. We're live with ElevenLabs today — your own stack (via Use Your AI) and Vapi are planned during or after the closed beta. Drop in an API key and an agent ID, and Call +AI handles the wiring to the call itself.

  • Inbound and outbound — independent settings
  • ElevenLabs today · Use Your AI & Vapi during or after beta

FAQ

Questions we hear often.

Who actually operates the service?
Call Plus AI provides only the software. The platform is operated by independent service providers — telcos, resellers, and partners — who run it for their customers, set pricing, and handle support. The same software can be operated by multiple service providers, so you're free to pick the one that best fits your region, compliance posture, and price point.
Do I need my own phone numbers?
Yes. Call +AI is a dialer and agent platform — we don't sell DIDs. You bring your own SIP trunk from any provider (Twilio, Telnyx, Bandwidth, etc.), register it as a SIP account in the app, and you're dialing.
Which AI agent providers are supported?
During closed beta we're live with ElevenLabs only. Support for bringing your own stack (via the Use Your AI provider) and Vapi is planned during or after the closed beta — more providers to follow at general release. Config is per-direction, so once those land you'll be able to mix providers (inbound on one, outbound on another) for the same line.
Where are recordings stored?
In our encrypted object storage in the region you select. Recording can be enabled or disabled per SIP account, with a global "never record" toggle for sensitive lines.
Is there an API?
Yes. Everything the app does is powered by our API — call history, SIP accounts, agents, screening rules, integrations. Documentation is published for every release; typed SDKs are rolling out during closed beta.
Can I white-label the mobile app?
On the Enterprise plan, yes. You get a branded build of the Android app — your name, your icon, your colors — and we help you ship it to the store.
What about HIPAA / PCI?
Recordings can be turned off per SIP account or globally. Enterprise customers get a BAA and a compliance review. We provide the primitives — encryption at rest, audit logs, redactable fields — so your compliance program can integrate cleanly.
