Know what your team is walking into.

Echo uses AI to understand what a 911 caller is describing while the call is still live. Your on-site team learns whether it is a medical emergency, a fire or an active threat, and sees the words that triggered the alert, before they get there.

Medical Emergency

Active Threat

Hi, I need help. We have someone on the third floor who isn't feeling well. He's dizzy and says he can't catch his breath.

Okay, is he conscious? Can you tell me how old he is?

Yeah, he's awake. Mid-fifties maybe. He's holding his chest and he's sweating through his shirt.

Is the pain just in his chest or is it spreading anywhere else?

He says it's going down his left arm and up into his jaw. We sat him down but he looks really pale.

Yeah, I'm calling from the north parking garage. I just saw something I want to report.

Go ahead, what did you see?

There's a guy on the third level who pulled what looked like a firearm out of his trunk. He put it in a bag and walked toward the building.

Can you describe him? What entrance was he headed toward?

White jacket, dark pants. Looked like he was heading for the east lobby entrance.

Context, not just keywords.

Literal matching flags exact terms the moment they are spoken. AI semantic analysis reads the conversation as a whole, so Echo recognizes a heart attack even when nobody says the words.

Emergency Context

Echo follows the call as it happens and tells responders whether they are heading into a medical emergency, a fire or an active threat.

Dual Keyword Detection

Instant literal matching at 100% confidence, plus AI semantic analysis every 15 seconds that catches what exact wording alone would miss.

Alerts Your Team Can Act On

Each alert carries the matched term, match type, confidence score and the words that triggered it, plus the call transcript and a link to the recording, so the AI flags the call and your people decide what to do.

Recordings for After-Action Review

Every call is recorded and transcribed, organized by organization and call record, so the full call is there for after-action review. No third-party storage.

Per-Org Control & Permissions

Each organization controls its own settings: turn recording and transcripts on or off independently, manage up to 15 keywords, and assign admin or viewer roles.

Portal Integration

Review alerts, read transcripts, play back recordings and manage keyword lists in the 9Line management portal. No separate tools needed.

From 911 call to on-site context, automatically.

Echo runs natively inside the existing 9Line SBC infrastructure. No extra hardware, no separate platform.

Echo

Watch it in Action

Security-first by design.

Echo follows the same security and operational standards as the rest of the 9Line platform, and AI analysis never leaves the 9Line environment.

Encrypted & Secure

AI analysis stays entirely within the 9Line environment through secure, encrypted endpoints.

Your Infrastructure, Your Storage

Recordings and transcripts are stored directly in your environment, organized by org and call record, following your existing security posture.

Granular Permissions

Admin and viewer roles keep configuration separate from read-only access. Control stays where it belongs.
