Context-Aware

Every call startswith context.

Contact history, CRM data, custom variables — injected into every prompt at call time. Your agent knows who it's talking to before it says a word.

Post-Call Intelligence

Every call becomesstructured data.

Sentiment, outcomes, action items — extracted automatically. Feed it back into your flows. Conversations that learn.

Transcript excerpt

Agent: I have Thursday at 2 PM available.

Caller: That works perfectly.

Not a Wrapper

We built the hard parts.

Rust backend, custom Pipecat fork, Kamailio SIP routing, active-active across US and EU. Most voice AI tools proxy someone else's stack. We run our own.

Carrier-Grade Telephony

Twilio, SIP/BYOC via Kamailio, WebRTC. Multi-region US and EU. We run the SIP bridge — not proxied through someone else's stack.

Custom Voice Pipeline

Built on a custom Pipecat fork with pre-warmed bots. Frame-based audio processing, sample rate handling, sub-second first response.

Real-Time Context Engine

CRM data, contact history, custom variables — injected at call time via Handlebars. NATS JetStream streams every event in real time.

Enterprise Infrastructure

Rust backend on Axum. AES-256-GCM credential encryption. DNC enforcement, TCPA compliance, MFA. Built in, not bolted on.

Why Now

Voice AI has no Stripe yet.

Everyone clones voices. Nobody orchestrates the conversation. The market is fragmented — no standard for call logic, context injection, or post-call intelligence. Talkif is building that layer.

Use Cases

Inbound Support

Answer with context.

Route by intent.

Escalate when needed.

Outbound Sales

Qualify leads at scale.

Timezone-aware campaigns.

DNC built in.

Scheduling

Book, confirm, remind.

All in one call.

How It Works

Four steps to your first voice agent

01

Get a number

Provision in one click or connect your Twilio / SIP carrier.

02

Build your flow

Drag-and-drop conversation design. Agents, functions, transfers.

03

Import contacts

CSV upload with CRM data. Every field becomes a prompt variable.

04

Go live

Assign the flow to your number. Inbound or outbound campaigns.

Build your first
voice agent.

From flow to live call in minutes. No credit card required.
