How does Smith.ai work for a law firm?
According to Smith.ai (features overview), it manages business calls and chats and offers live agents who answer around the clock. Its home page sorts the service into three approaches: 100% AI, hybrid and 100% human (plan overview). The same page calls the all-AI approach fast and efficient, with some limitations, and the all-human approach warm and skilled with nuance, but harder to scale (plan overview).
For a law firm, that choice decides who hears a new caller describe a car crash, a custody dispute or an arrest. The hybrid approach puts AI on routine calls and live agents on complex ones (plan overview). The firm's own intake rules then decide which calls count as routine and which count as complex.
Smith.ai prices both its AI-first and hybrid options per call, as of November 2026 (plan overview), so the monthly bill tracks inbound call volume. Smith.ai's integrations page says firms can automate work by combining it with the apps they use (app integrations page). Before signing up, the firm writes down the case management system, calendar and CRM that intake details need to reach. A side-by-side with a live-receptionist rival is in Ruby vs Smith.ai on pricing, AI options and HIPAA.
Intake questions to give any answering option
Whichever option a firm picks, the intake script needs the same answers. The table lists six questions, their answer options and the CRM field each one fills.
| Intake question | Answer options | CRM field |
|---|---|---|
| What type of legal matter is this? | Personal injury, family, criminal defense, estate planning, business, other | Matter type |
| Which state and county is the matter in? | State name and county name | Jurisdiction |
| Is there a court date, filing deadline or recent arrest? | Yes with the date, no, not sure | Urgency: urgent or standard |
| Who is on the other side? | Full names of the other parties | Adverse party, for the conflict check |
| What is the best phone number and email? | Number, email, preferred channel | Contact details |
| How did you find the firm? | Search, referral, ad, directory | Lead source |
Two booking rules sit on top of the table, set up as calendar slot types named Urgent consult and Standard consult. An urgent answer books the earliest open Urgent consult slot, and a standard answer books the next Standard consult slot. No caller gets legal advice, and the script says an attorney answers legal questions at the consultation.
How does Retell AI work for a law firm?
According to Retell AI (build and QA overview), teams can build complex call flows visually, and its home page lists build, test, deploy, QA and analytics stages. The same page puts the QA ceiling at 100% of AI calls, saying teams can "measure performance at scale, surface patterns across conversations" (build and QA overview). For a firm, that review step is where intake staff check whether the agent asked about jurisdiction and urgency on each call.
Retell AI's integrations page says a HubSpot connection lets agents greet callers by name, reference open deals and prior commitments, and log every call automatically (integrations page). The same page says a GoHighLevel connection lets the voice agent work from live sub-account data (integrations page).
Retell AI's pricing page says Retell starts at $0 and a team pays only for what it uses, as of November 2026 (usage pricing page). The Retell AI per-minute pricing breakdown covers the cost parts behind that usage model.
Building a law firm intake flow in Retell
A firm on Retell does the build itself, in the visual call-flow builder its home page describes (build and QA overview). A workable order looks like this:
- Turn each question in the intake table into a step in the flow, in the same order.
- Add a branch for urgent answers that offers only the earliest open consultation slot.
- Write the line that declines legal advice and promises an attorney at the consultation.
- Connect the firm's CRM so the six intake answers land in the matching fields.
- Place test calls for each matter type, including an urgent criminal call.
- Review the QA results and fix any step where the agent skipped jurisdiction or urgency.
Personal injury firms can add questions about injuries and insurance, as set out in AI voice agents for personal injury intake.

Why reply speed matters for intake
Research from Harvard Business Review (2011 lead response audit) found that of 2,241 U.S. companies audited, 37% responded to their lead within an hour, 16% within one to 24 hours, and 24% took more than 24 hours. The same 2011 audit reported that firms that tried to contact a lead within an hour were nearly seven times as likely to qualify it as firms that waited even an hour longer (2011 lead response audit).
Leads called within 60 seconds converted 391% above average (Velocify, formerly Leads360). This is an industry benchmark, not a Novacall AI customer outcome. The study was first published in 2010.
Example: assume a hypothetical firm receives 40 new-client inquiries a month outside office hours and books one in four of them, which makes 10 consultations a month that depend on a reply while the office is closed.
Where Novacall AI fits
A firm that wants every new inquiry answered on the channel the lead chose, phone or not, can look at an AI lead response alternative to Retell. The AI responds to inbound leads in under 60 seconds, 24/7/365. It responds by voice, SMS, email or WhatsApp, in 15+ languages. It asks the qualification questions on the call. It books the appointment on your calendar. It syncs the lead's details to your CRM.
The firm's staff take over from each step, as the table shows.
| AI step | What the firm's staff do next |
|---|---|
| Reply on the lead's channel | Intake coordinator opens the new CRM record at the start of the next business day |
| Qualification questions on the call | Intake coordinator runs a conflict check on the adverse party name and sets Conflict check status to cleared, pending or conflict |
| Consultation booked on the calendar | Assigned attorney reads matter type and jurisdiction before the consultation |
| Lead's details synced to the CRM | Staff send engagement paperwork after the consultation |
| Urgent answer, such as an arrest or an imminent hearing | On-call attorney calls back from the booked appointment or CRM record |
The platform supports TCPA, A2P 10DLC, DNC, consent handling, call recording, GDPR/CCPA and SOC 2. Novacall AI pricing is by custom quote, based on lead and call volume, channels, integrations and workflow.
Example call script (illustrative, not a recording)
Scenario: a caller phones after hours about a car accident.
Agent: Thanks for calling. Are you reaching out about a new legal matter?
Caller: Yes. Someone rear-ended me last night and my neck still hurts.
Agent: I'm sorry that happened. Which state and county was the accident in?
Caller: (names the state and county)
Agent: Thank you. The other driver's name, if you have it, helps the firm prepare. Is there a court date or deadline you already know about?
Caller: No court date, but the other driver's insurer already called me.
Agent: I can't give legal advice, but an attorney can answer that at your consultation. Would tomorrow morning or tomorrow afternoon suit you better?
Caller: Morning, please.
Agent: You're booked for tomorrow morning. What's the best number and email for the attorney to reach you?
Second scenario: a parent calls late at night about an arrest.
Caller: My son was arrested tonight and he has a hearing in the morning.
Agent: I'm sorry you're dealing with this. Which state and county is the hearing in?
Caller: (names the state and county)
Agent: Because the hearing is in the morning, I'll book the earliest consultation the firm keeps open for urgent matters. What's your full name and the best number to reach you tonight?
Caller: (gives a name and number)
Agent: Thank you. You're booked, and an attorney from the firm will call you back from that booking.

Frequently asked questions
What is the difference between an AI receptionist and an answering service?
An answering service puts trained people on the phone to take messages or follow a script. An AI receptionist uses voice software to answer, ask intake questions and book time. Hybrid services split routine and complex calls between the two.
Can an AI voice agent book a legal consultation?
Yes, when the firm connects it to the calendar it already uses and sets intake rules first. Those rules decide which matter types get booked, which slots stay open, and which inquiries wait for an attorney to review.
Can a law firm keep its current phone number?
A firm can keep its published number and use its phone carrier's call-forwarding setting to send calls onward. The forwarding rule can apply all day, only after hours, or only when the main line is busy.
What should happen to an urgent legal matter after hours?
The firm decides ahead of time what counts as urgent, such as an arrest or an imminent hearing. Those inquiries get the earliest open slot, and the on-call attorney calls back from the booked appointment or CRM record.
Which option suits a small law firm with no technical staff?
A firm without anyone to design and test call flows should weigh how much building each option asks of it. A managed answering service asks the least, while a build-it-yourself voice platform asks the most from the firm.
