Phone line

An AI that answers your phone.

Eljae picks up a number we set up for you, around the clock, answers from your knowledge base, and brings in your team when a call gets unclear or sensitive.

From $39/mo on its own, or included with Pro at $99/mo · minutes or calls included, with a firm limit · no setup fee

Today, Calls: an open call showing a callback request, its summary and the start of the transcript — **Calls.** Every call summarized, and callback requests flagged. A demo company, sample data.

The coverage gap

The phone keeps ringing even when your staff has to stop.

Every call you miss is a customer who called your competitor instead, a patient who never booked, or a question that just sits there until Monday. Voicemail doesn't really cover you, and a bigger phone menu isn't an answer either. The Phone line picks up on the first ring at 2am the same way it does at 2pm — using the same knowledge that powers your web chat, so callers hear the same answer as your website and your team. When it can't help, it doesn't make something up — it hands the call to a real person.

What it does

A real conversation, not a phone menu.

Answers 24/7 on a number we set up for you. Give it out — or have your phone company forward your existing line to it — and you get always-on coverage: no gap after hours, no pile of voicemails, no "please call back during business hours."
Answers based on real facts, spoken out loud. Every answer comes from your knowledge base — the same self-correcting source behind your web chat. Fix an answer once in the Command Center, and it's live on the phone on the very next call — no retraining, no new release needed.
Hands off to a person. When a call is unclear or sensitive, the agent takes the caller's details and alerts your team — or, if you set a transfer number, connects the call — instead of making something up.
Writes down every call. Each call's transcript and summary are emailed to your team. Recording is off unless you turn it on — and if you do, callers are told the call is being recorded.
Sends the same alerts as chat. Phone uses the exact same hand-off system as your web chat, so a phone hand-off sends the same email and team alert — one process across every channel.
Says it's an AI, right away. Every call the AI answers starts by telling the caller they're talking to an AI, and it is instructed never to pretend to be a person — a platform rule your settings can't turn off.

Your number, your website

Works with what you already have.

Lina provides the number. On Pro and Complete we set up a phone number for your organization and the agent answers it. Print it, put it on your site, give it out.
Already have a number people know? Most carriers can forward its calls to your Lina number — all calls, after hours, or when the line is busy. Forwarding is a feature of your phone company's service, set up with them; Lina doesn't move your existing line. If you forward it, the number you give Lina for urgent calls must be a mobile or desk phone — never the line you forwarded to Lina.
Keep your website. Paste one line into it, and a chat button appears on every page; or add a “Chat with us” link to your Lina help page. Callers and visitors get the same answers from the same knowledge.

Limits, cost control, and how it's built

The cap, plainly

What happens when the included minutes run out?

Your assistant stops answering calls until the next month starts, and new calls ring through to the phone number you chose for urgent calls — or go to voicemail if you haven’t chosen one. Before it rings, a caller hears “Thanks for calling [your organization’s name] — putting you through now.” We email you at 80% and 100% of your minutes so it never catches you by surprise, and extra minutes are quoted, not billed: email support@linasystems.org before a busy stretch and we agree a price first. Your plan price never changes on its own.

Cost is bounded

Every call has a built-in spending limit.

Voice AI with no limits is exactly how bills get out of control. The Phone line sets a cost cap on every single call before it even starts, so a busy day or a caller stuck on the line can't turn into a surprise charge.

A time limit on every call, with a spoken warning. You set how long a call can run, and the caller hears a heads-up before it ends — no call goes on forever.
A limit on calls happening at once. A cap on simultaneous calls keeps your peak cost in check, even during a busy surge.
Minutes included, with a firm limit. Pro and Complete include a set number of phone minutes each month. When they run out, the assistant stops answering and calls ring through to your own phone (or go to voicemail if you haven’t set a number), so you never get a per-minute bill. The Phone Line on its own is counted by the call instead: 100 answered calls a month, then 40¢ a call from prepaid credits — and with no credits left, calls ring through the same way.
A number we set up for you. Your organization's phone number lives in our phone account and we set it up — you don't need your own phone-company account or bill.

Phone minutes and AI answers are included up to a monthly limit — we email you when you're at 80% and 100%, and your plan price never changes. Expecting a busy stretch? Talk to us and we'll agree on extra capacity first.

Built on real infrastructure

Real, working technology — not just a demo gadget.

The agent runs on a Twilio + Google Gemini Live connection: Twilio carries the phone call, Gemini Live handles the conversation, and your knowledge base supplies every fact it uses. It's the same engine that answers Lina’s own phone line — built on a platform running in production, not a prototype. Almost all of the setup is content you fill in. You can set it up yourself in the dashboard, and it starts answering as soon as you add your information. Want a hand? Book a free setup call.

Verified incoming calls. Every call into the system is checked with a digital signature, so only real, legitimate calls get through.
Rejects anything it can't verify. If a request can't be confirmed as genuine, it's turned away rather than let through.
Your own sealed space. Your phone agent runs in your own isolated space — your data, your brand — never mixed in with any other customer.
Checked before every update. Every change has to pass our automated tests and a scan for leaked passwords before it goes live.

Editions & plans

Included with Pro and Complete — or on its own.

The Phone line comes with Pro ($99/mo) and Complete ($349/mo) — we set up a phone number for your organization and it starts answering. Just want the line? The Phone Line product is $39/mo on its own: 100 answered calls a month (up to 5 minutes each), then 40¢ a call, prepaid — see it on the pricing page. Same system, two ready-made setups:

Business edition

An AI front desk

Built for the front desk of any business or nonprofit. The phone agent answers customer and support questions 24/7 — hours, services, how to book — basing its answers on your knowledge base, and hands off to staff for anything sensitive. Included in Pro and Complete.

Campaign edition

Adds answers to voters' questions, day and night

Everything in Business, plus what an election needs. The phone agent answers voter and constituent questions around the clock, basing its answers on your knowledge base and key facts, and hands the call to your field team when it needs a person. Included in Pro and Complete.

For comparison: voice-AI companies usually bill you per minute, so the cost is hard to predict. Here the phone agent is part of the plan — $99 a month (Pro) with minutes included and a firm limit, so there's no per-minute bill. On its own, the Phone Line is $39 a month with 100 answered calls included, then 40¢ a call, prepaid — still never a per-minute bill. See full pricing →
