Voice & Conversational AI
Custom AI Voice Agents That Answer, Qualify and Book Every Call
Built for law firms, healthcare practices, financial services, B2B sales and support teams, and field-service businesses. Replace missed calls and bloated reception desks with real-time conversational agents built directly into your scheduling and CRM stack.
What is a custom AI voice agent?
A custom AI voice agent is software that answers phone calls in natural, real-time speech, works out why the person is calling, asks the questions a human receptionist would, and then books the appointment, routes the call or writes the intake into your CRM or case-management system. It hands off to a person whenever the situation needs one.

What it handles
Eight jobs that cover the life of a call, from the first ring to the record in your system.
Qualification & routing
Branching questions decide who the caller is and what they need, then send the call to the right person, queue or follow-up.
Booking & reminders
Appointments are booked straight into your calendar, with confirmations and reminders sent by text.
Outbound follow-up
Callbacks, missed-call follow-ups and renewal reminders, run within the calling rules that apply to you.
Support & status calls
Routine questions and status checks are answered from your own systems, so staff handle only what needs judgement.
CRM & case-management updates
Each call becomes a record in your CRM, case-management or practice-management system, with the fields filled in, the transcript attached and follow-up tasks created.
Handoff to a human
When a caller asks for a person, or the agent reaches the limit of what it should handle, the call is passed over with the context attached.
Continuation by SMS or webchat
The same conversation carries on by text or on your website, so a caller who hangs up is not lost.

Ready-made vs. custom: choosing the right build
A subscription is the right answer for simple calls. Throughline is the faster route when you want a proven intake flow. A custom build earns its cost when your phone system, records software or data rules are specific to you.
| Generic AI receptionist subscription | Throughline (ready-made) | Custom build | |
|---|---|---|---|
| Time to live | Minutes to days | 2-4 weeks, depending on requirements | Scoped on the call |
| What you get | A general-purpose agent configured from a form | A law-firm intake agent, ready to run and tuned for the job | A voice agent designed around your call flows |
| Voice and accent | A choice of preset voices | One standard voice | A regional accent of your choice, tuned to the callers you serve |
| Integrations | A fixed list, usually calendar and email | HubSpot, Gmail, Slack and Zapier | Your phone system and your case-management or health-record software |
| Many clients on one platform | Rarely | No | White-label and multi-tenant, as in the 48-firm platform |
| Data residency and controls | Set by the vendor | Set by the hosted product | Designed to your requirements |
| Cost shape | Monthly subscription plus usage | Subscription plus usage | Scoped build fee plus usage |
| Best fit | A single office with simple calls | A firm that wants a proven intake flow now | Platforms, regulated teams and anyone with non-standard systems |
How it works
From the phone line to your records, with a person available at every step.
Step 1: Phone line
A carrier or SIP trunk delivers the call, on a number you already own or a new one.
Step 2: Real-time speech model
Speech is understood and answered as it happens, with no menu tree and no awkward pauses.
Step 3: Structured intake
The agent asks the questions your process needs and records the answers as fields, not a transcript blob.
Step 4: Qualification rules
Your rules decide whether the caller is a fit, how urgent they are and where they go next.
Step 5: CRM or case-management update
The intake is written into your CRM, calendar or case-management system through its API.
Step 6: Human handoff and audit trail
A person takes over when needed. Call logs, transcripts and cost per minute are kept for review.
Compliance and trust guardrails
Voice raises questions that text does not. These are designed in from the start, not added at review.
The caller knows it is AI
The agent says at the start of the call that it is an AI assistant, and answers honestly if asked.
Recording consent
Disclosures and consent prompts are built for states that require every party's consent to record.
Outbound calling rules
Outbound flows respect do-not-call lists and the calling-hours and consent rules that apply to your use case.
No legal, medical or financial advice
The agent collects information and books next steps. It is bounded so it does not give advice a licensed professional should give.
PII masking and retention limits
Personal details can be masked in logs, and recordings and transcripts are kept only as long as you decide.

What drives cost
- Call minutes: how many calls you take and how long they run.
- AI and telephony costs: speech-model and carrier usage is billed per minute.
- Integrations: a calendar is quick; a case-management or health-record system takes more work.
- Languages and accents: each additional language or regional accent is tested and tuned separately.
- Number of clients on one platform: multi-tenant and white-label setups add configuration and admin tooling.
Frequently asked questions
It can replace the first-line work: answering every call, taking intake, booking and routing. It does not replace judgement. Most teams keep a person for sensitive calls and escalations, and the agent hands those over with the context already collected.
Yes. The agent states at the start of the call that it is an AI assistant, and it answers honestly if asked. The speech is natural, but we do not try to pass it off as a person.
It depends on what you need. A single office with simple calls may be well served by a generic AI receptionist subscription. If you need intake written into your case-management system, rules specific to your practice or control over where data lives, a purpose-built agent is a better fit. We build these, so we are not neutral. Test any service with your own after-hours scenario before you commit, ours included.
A voice agent can be designed with HIPAA in mind: access controls, encryption, limits on what is stored, and business associate agreements with the vendors involved. Compliance depends on the whole setup, not on the software alone, so we scope it with your compliance lead rather than promise it in advance.
There is no single figure. Speech-model and telephony usage is billed per minute and varies with the providers and models chosen. Call logs show cost per minute, and we agree an estimate based on your expected call volume during scoping.
Support depends on the speech model and on testing with real callers. English is the baseline. Custom builds can also be tuned to a regional accent of your choice, so the agent sounds like the people calling. Other languages and accents are scoped and tested with real callers individually, so quality is verified rather than assumed.
Throughline, the ready-made law-firm agent, typically goes live in 2-4 weeks, depending on your requirements such as integrations and call flows. A custom build is scoped on the call, since the timeline depends on integrations, call flows and compliance review.
Your call data is yours. For a custom build, code ownership is agreed in the contract and we are happy to hand over the repository. Throughline is a hosted product, so you use it rather than own its code.
