Voice AI
Voice AI is an agent on a phone line: it answers the call, qualifies the request, books the appointment — then hands anything else to a person.
For agencies whose clients run on the phone — local services, clinics, intake-heavy businesses — and miss calls they paid marketing dollars to generate.

Where a voice build gets hard.
Every voice demo sounds fluent — fluency is the commodity part. The engineering lives in the seams: latency a caller will tolerate, interruptions, accents, and the moment the conversation leaves the script.
The design rule we hold: a voice agent should do a narrow job well and exit gracefully. It identifies itself as automated, it transfers to a human on request — every deliverable includes that path — and it never bluffs through a question it can’t answer. A caller who hangs up on a confident-sounding wrong answer is your client’s lost customer.
Voice is the newest line we offer. Builds are quoted from the published range, and the engagement model is unchanged: a fixed price in writing before work starts, pilot first.
If the job is conversational but doesn’t need a phone line, you’re scoping a chatbot. Read about AI chatbots.
Where a voice agent fits.
Missed and after-hours calls
The client pays for calls that ring out at 6 p.m. A voice agent answers every one, books what can be booked, and leaves a transcript — the callback list is triaged before the team sits down in the morning.
Intake qualification
Phone-heavy intake — clinics, legal, home services — where the first five minutes are the same structured questions every time. The agent collects the structure; the professional starts at the interesting part.
Appointment scheduling
Booking, rescheduling, and confirmations against a live calendar. Narrow, high-volume, and unambiguous — the shape of job voice agents are right for.
Status lines
Order status, appointment confirmation, opening hours — questions with database answers that don’t need a person but currently interrupt one.
Example voice builds.
Illustrative examples — the shape of work this line covers, not client case studies. Builds are quoted fixed-price from the published range ($4,000–$12,000 / build) before work starts.
After-hours receptionist
Answers when the office doesn’t, books directly into the calendar, transfers urgent calls to an on-call number, and emails a transcript of every conversation by morning.
Intake line
Runs a structured intake conversation, writes the answers into the client’s CRM as fields rather than a blob, and schedules the follow-up with the right person.
Reminder and confirmation calls
Outbound reminders for booked appointments — placed only with the recipient’s consent on record, with clear disclosure that the call is automated.
How we build voice agents.
Voice gets scoped around its failure modes first: what happens when the caller interrupts, goes off-script, or asks for a person. The transfer path is designed before the happy path — a voice agent without a graceful exit is a trap for your client’s customers, and we don’t ship those.
QA happens on real calls: a written set of test conversations — including the must-transfer and must-refuse cases — runs against the build before you hear it. Recording and disclosure behavior is configured to your client’s compliance requirements; their counsel sets the policy, we build to it. Transcripts and call logs land in systems the client controls.
The mechanics are the same on every line we ship:
- 01Pilot first — Every relationship starts with one real project: $1,000 flat, two weeks, fully credited toward month one of any retainer.
- 02Scoped in writing — Scope, milestones, and — on fixed-price work — the price, signed before work starts. The spec is the contract QA runs against.
- 03One point of contact — Javid scopes every project and answers inside four business hours; every active engagement gets a written status each Friday.
- 04Founder QA — Every deliverable is checked against the signed spec before you see it — behavior, edge cases, and security.
- 05White-label handover — Repos, credentials, and docs transfer to accounts you or your client control. Nothing we ship carries our name.
- 0690-day warranty — If a delivered build doesn’t match its signed spec, we fix it free for 90 days after handover.

Questions about voice AI.
Will callers know they’re talking to an AI?
Yes — the agent says so up front. Some jurisdictions require disclosure, and pretending otherwise is a bad trade anywhere: the goal is a handled call, not a passed Turing test.
What happens when it can’t handle a call?
It transfers — to a live line during hours, to a logged callback with a transcript after hours. The must-transfer cases are written into the spec, and “let me get you a person” is always preferred over improvising.
What does a voice build cost?
Builds are quoted from the published $4,000–$12,000 range, fixed in writing before work starts. Where a build lands depends on the telephony setup, the systems the agent writes into, and call volume. Every relationship starts with a $1,000 pilot.
Can it use our client’s existing phone number?
Usually, yes — numbers can typically be forwarded or ported to the telephony layer without changing what customers dial. The routing plan is part of the written scope.
