A consistent first response for every legal inquiry
A prospective client may call during a hearing, after business hours, or while the intake team is already speaking with someone else. If the call reaches a generic voicemail, the firm receives an incomplete message and the caller may keep looking.
ThunderPhone gives a law firm an AI phone agent for first-response intake. It can answer immediately, explain that it is an AI assistant, collect the fields the firm requires, check approved scheduling availability, and route eligible calls. It does not need to offer legal advice to be useful.
Give every call the same disciplined intake path
A law-firm agent can be configured to:
- identify the firm and disclose its role at the beginning of the call;
- collect the caller's name, contact details, matter type, relevant location, opposing-party names, and important dates;
- explain that the conversation does not create an attorney-client relationship;
- avoid legal opinions, predictions, or strategy;
- schedule a consultation through an approved calendar connection;
- flag deadlines or urgent circumstances using rules written by the firm;
- transfer qualified or time-sensitive inquiries to the right team; and
- send structured intake data to the firm's own system through an approved integration.
Conflict checks and legal judgments stay with the firm. The agent's job is to collect, confirm, and route—not decide whether the firm can represent someone.
Sample legal-intake call flow
Agent: Thank you for calling Northline Legal. I am the firm's AI intake assistant. I can collect information and help schedule a consultation, but I cannot provide legal advice. What type of matter are you calling about?
Caller: My former employer sent me a letter today, and it says I have ten days to respond.
Agent: I can record that deadline for the intake team. What date is shown on the letter, and what state are you in?
Caller: The letter is dated August 4, and I am in California.
Agent: Thank you. I will not ask you to describe confidential strategy. May I collect your full name, phone number, email address, and the employer's name for the firm's conflict-screening process?
Caller: Yes.
Agent: I have the details. Because you mentioned a response deadline, I will try the employment intake team now. You may hear hold music while I privately explain who is calling and why.
On an eligible production number, the agent can attempt that warm transfer. If nobody accepts, it returns to the caller, confirms the message, and follows the firm's fallback—such as booking the earliest available consultation.
Ten phone workflows a firm can configure
Each workflow below is defined by the firm's own script, routing rules, and integrations. The agent executes the steps; the firm keeps every legal judgment.
After-hours and overflow intake
When the intake desk is closed or every line is busy, the agent answers instead of voicemail. It runs the same scripted first-response questions the daytime team uses—matter type, contact details, parties, dates—and posts the completed record to the firm's intake system through a signed webhook or connected API. Time-sensitive callers can be escalated under the firm's after-hours policy; everyone else gets a scheduled callback or consultation slot rather than a dial tone.
Practice-area routing
The agent asks what the call is about, classifies the matter against the practice areas the firm has defined—family, employment, personal injury, estate planning, criminal defense, or any custom list—and follows the routing rule attached to each one. A covered practice area can go to that group's intake queue or transfer target; an uncovered one triggers the firm's approved decline-and-referral language instead of a vague brush-off. Keypad menus can sit in front of the agent when the firm prefers callers to self-select first.
Conflict-screening data collection
Before any consultation, most firms need the names required for a conflict check: the caller's full name and any other names they use, opposing parties, and related businesses or individuals. The agent collects and confirms those names letter by letter where spelling matters, records the matter description, and delivers the package to the firm's screening workflow via webhook. The agent never states whether a conflict exists; the firm's staff run the check and make the determination.
Urgency and deadline triage
The firm writes the trigger rules: a caller mentions a court date, a served complaint, a letter with a response window, an arrest, or any other condition the firm treats as time-sensitive. When a rule fires, the agent records the dates exactly as the caller states them, marks the intake record as urgent, and attempts the configured escalation—typically a warm transfer to the on-call attorney or intake lead, falling back to an immediate flagged handoff message if no one accepts. The agent never advises whether a deadline is legally significant; it captures the facts and moves the call up the priority path the firm defined.
Consultation scheduling
Connected to an approved calendar or scheduling API, the agent offers only the slots the firm exposes—by practice area, attorney, office, or consultation type—books the appointment, and reads the confirmed date, time, and location back to the caller. Booking details flow into the intake record so the consultation and the screening data arrive together.
Existing-client routing versus new-matter intake
An early question—"Are you currently working with our firm?"—splits the flow. Existing clients can be routed by matter or attorney name under the firm's rules: a cold transfer to the right assistant, a message recorded against the matter, or a scheduled callback, without repeating a full intake script. New callers continue into the standard intake path. The firm decides how much verification an existing-client claim requires before any routing happens.
Court-date and appointment reminders (outbound)
For clients who have consented to calls, an outbound campaign can place reminder calls ahead of court dates, depositions, mediations, or consultations, using the firm's approved wording and confirming that the client knows the date, time, and location. Voicemail detection can leave a firm-approved message or trigger a retry later under the campaign's retry policy, and every outcome—confirmed, rescheduling requested, no answer—posts back to the firm's system so staff see who still needs a human follow-up.
Document-request follow-ups (outbound)
Signed engagements often stall while the firm waits on identification, contracts, medical releases, or correspondence. An outbound follow-up campaign can call clients with outstanding requests, remind them which documents are still needed, capture a stated reason or expected date, and offer a transfer to a paralegal when the client has questions the script does not cover. Results land in the matter record so the document chase stops depending on someone's memory.
Bilingual and multilingual intake
The agent supports 47 languages and can switch mid-call when a caller uses one of the additional languages the firm has configured, so a caller who opens in English and continues in Spanish completes the same scripted intake without being asked to call back. Captured fields arrive in the intake system in the structure the firm defined regardless of the conversation's language. Premium voice or language paths can add up to 3¢ per minute.
Callback management
When a caller cannot wait, the right person is unavailable, or a transfer attempt fails, the agent records a callback commitment: preferred times, preferred number, and the reason for the call. That record reaches the responsible team through the same webhook pipeline as intake, and an outbound agent can place the callback within the firm's approved window—so "we'll call you back" becomes a tracked task instead of a sticky note.
Features that matter to a law firm
Prompted boundaries
Write explicit rules about what the agent may discuss, which disclaimer it must give, what it must never promise, and which facts it must confirm back to the caller. Specific boundaries are easier to test than a broad instruction to “be careful.” For a law firm the first boundary is licensed activity itself: the agent never gives legal advice, never evaluates the merits of a matter, and never performs legal work — it collects facts, schedules, and routes.
Structured intake through integrations
The agent can use a connected app, API, or MCP server to create a lead or intake record while the conversation is happening. Webhook deliveries are HMAC-signed, so the receiving system can verify that each intake record genuinely came from the firm's agent. The receiving system determines which fields and actions are available.
Cold and warm transfers
Use an immediate cold transfer when speed matters. On eligible production VoIP or SIP numbers, a warm transfer lets the agent place the caller on hold, privately brief the attorney or intake specialist, and connect the parties only after acceptance.
Voicemail and unavailable-recipient handling
For outbound calls, voicemail detection can be configured to let the prompt decide, hang up, or leave a predefined message, and campaigns can retry voicemail outcomes under their retry policy. If a transfer recipient does not answer, a warm-transfer flow can return to the original caller and collect next steps.
Searchable firm knowledge
Attach approved practice-area descriptions, office information, consultation policies, and intake instructions—text, Markdown, CSV, PDF, or DOCX files, or content imported from a URL. The agent can search those sources during a call and escalate when the material does not answer the question.
A website channel on the same rules
The embeddable web widget lets a site visitor start a voice conversation with the same agent, under the same script, boundaries, and integrations as the phone line. Widget sessions produce the same transcripts, recordings, and grading data as phone calls, so web intake and phone intake are reviewed in one place.
Call review and simulation
Calls can produce transcripts, recordings when enabled, and grading against the firm's own criteria. Before launch, simulate deadline questions, out-of-scope matters, angry callers, repeat clients, and requests for legal advice; graded scenarios can run as a regression suite so a script change that weakens a boundary fails the test before it reaches a real caller, and A/B experiments can compare script variants on live traffic.
What would this cost each month?
Suppose a firm handles 600 AI-assisted calls per month, averaging 4 minutes each:
600 calls × 4 minutes = 2,400 minutes per month
- Spark:
2,400 × $0.02 = $48/month - Bolt:
2,400 × $0.05 = $120/month - Storm:
2,400 × $0.09 = $216/month
That is base engine usage, not a quote. Premium voice or language paths can add up to 3¢ per minute, and phone-number or carrier charges depend on the telephony setup. Hold time bills a flat 2¢ per minute; voicemail and phone-menu minutes bill at the engine rate. Optional add-ons such as verbal acknowledgements, call supervision, and long prompts carry their own published surcharges. The agent builder shows the current all-in rate before calls are placed.
Frequently asked questions
Can an AI phone agent give legal advice?
ThunderPhone can be instructed not to give legal advice and to limit itself to approved information, intake questions, scheduling, and routing. The firm remains responsible for the prompt, workflow, review, and legal-service boundaries.
Can it perform a conflict check?
It can collect and confirm the names and details a firm uses for conflict screening, then send them to an approved system. The firm should make the actual conflict determination.
Can the agent schedule consultations?
Yes, when connected to an approved calendar or scheduling API. It can offer available times, create the appointment, and repeat the confirmed details to the caller.
What happens to urgent or deadline-sensitive calls?
The firm defines the trigger words, questions, and routing path. When a caller reports a covered deadline or urgent condition, the agent can mark it in the intake record and attempt the configured transfer or escalation. The agent records the dates; it does not assess their legal significance.
Can calls be transferred to an attorney or intake specialist?
Yes. Cold transfer is available for immediate routing. Warm transfer is available on eligible production numbers with outbound SIP capability and allows a private briefing before the caller is connected.
Can the agent work after business hours?
Yes. A deployed agent can answer calls routed to its number outside office hours, collect a complete intake, schedule within allowed availability, or follow an after-hours escalation policy.
Can it handle callers who do not speak English?
Yes. The agent supports 47 languages, and a firm can configure additional languages so the agent switches automatically mid-call when a caller uses one of them. Premium voice or language paths can add up to 3¢ per minute.
Is ThunderPhone appropriate for confidential intake calls?
ThunderPhone is GDPR and HIPAA compliant. The firm remains responsible for configuring its workflows, recordings, retention, integrations, and caller notices to meet its own professional and regulatory obligations, including its confidentiality duties.
