Voice AI Agency For US Businesses A Remote Dedicated Developer

A remote mid-to-senior developer who builds and runs your AI phone agents: AI receptionists, after-hours answering and outbound reminders on your own Twilio or Telnyx numbers, with TCPA consent, state recording rules and HIPAA calls handled in the build. Live with your Eastern morning, invoiced monthly in USD.

AI Voice Agents From Empiric Infotech LLP

Empiric Infotech LLP works as a voice AI agency for US businesses, with one difference from most agencies: a remote dedicated developer builds your AI voice agents inside your own telephony and cloud accounts and keeps tuning them after launch. The agents answer and place real calls: an AI receptionist for the front desk, after-hours answering that books appointments instead of taking messages, reminder calls, lead qualification and order-status lines, in English and Spanish. US calling has rules that shape the build. The FCC has confirmed that AI-generated voices count as artificial voices under the TCPA, so outbound calls need prior consent, and marketing calls need it in writing. California, Florida, Illinois, Pennsylvania and Washington are among the states that require every party's consent to record a call. SMS confirmations need A2P 10DLC registration, and clinic calls carry protected health information. Your developer joins your standup in the Eastern morning, reviews the previous day's call recordings with you and leaves a written handover each day. A senior team lead reviews and tests every release.

What our voice AI agency delivers for US businesses

Phone agents that callers stay on the line with, built to US calling rules and tuned every week by the developer who built them.

AI receptionists and after-hours answering

Inbound agents on your Twilio or Telnyx numbers, or behind your RingCentral, Dialpad or Aircall line, with sub-second responses once tuned. They identify the caller, answer common questions and book into Calendly, Acuity or your practice-management system instead of taking a message.

Outbound calls with TCPA consent built in

Reminder, follow-up and qualification calls that check a consent record before dialing, honour the National Do Not Call Registry and your internal list, call only between 8:00 AM and 9:00 PM in the recipient's time zone, and log an opt-out the moment a caller asks.

Recording notices by state

A recording disclosure at the start of every call, worded for all-party consent states, with recordings and transcripts stored in your own AWS or Azure account under the retention period you set.

HIPAA-ready calls for clinics and dental groups

For practices that discuss appointments and treatment, calls run on telephony and model services covered by a BAA, recordings are encrypted, and transcripts mask protected health information before anything reaches analytics.

Contact center and CRM integration

Warm transfers into Amazon Connect, Five9, Genesys Cloud or a ring group with a whispered summary, and two-way updates to Salesforce, HubSpot, ServiceTitan or Follow Up Boss so every call becomes a record your team can act on.

Spanish calls and trusted caller ID

Bilingual English and Spanish flows with natural voices, A2P 10DLC registration for SMS confirmations, and caller ID set up for STIR/SHAKEN attestation with registered business profiles, which helps keep outbound calls from being labelled as spam.

How a US voice AI engagement starts

From a first call to an agent answering a test number within the week, scheduled on US hours.

A call in your morning

Thirty minutes on your time zone. Walk us through the calls you want handled, your call volume by hour, the phone system you use, and whether calls touch patient or payment data.

Call flows and a consent plan in 24 hours

A written scope with the first call flows, the voice stack, the integrations, the consent and recording rules for the states you call, and an introduction to one developer. The NDA and IP assignment are signed and our W-8BEN-E goes to your finance team.

A 7-day risk-free trial on a test number

Your developer starts within 48 hours, and by day 7 your priority inbound flow answers a test number, books into a sandbox calendar and warm-transfers to your team. Full refund if it is not a fit.

Monthly in USD after that

Monthly while you add flows and outbound campaigns, hourly for a defined change. One USD invoice, and seven days' notice to stop.

Voice AI agent pricing for US businesses

Two plans, invoiced in USD, each with a senior team lead who reviews and tests every release. The monthly plan is a developer working full time on your voice agents for 160 to 172 hours, billed monthly upfront, with a 7-day risk-free trial. The hourly plan covers a contained change, such as one outbound campaign, a Spanish flow or a consent audit. AI voice work carries a higher hourly rate than our standard work because real-time latency and telephony tuning are specialist skills; the monthly rate matches every other dedicated developer. Per-minute telephony, speech and model usage is billed to your own accounts at cost.

Talk to us

Most US voice work starts with one developer on one inbound line, often the front desk or after-hours. Outbound reminders, a Spanish line or a second location usually bring a second developer, at the same monthly rate per person, with the senior team lead keeping every agent on the same review and testing standard at no extra charge.

The first 90 days of a voice agent with a US team

Built around a short morning review of real call recordings and a written handover each day.

Week 1
Telephony access and a test-number agent
Access to your Twilio, Telnyx or phone-system account, the voice stack chosen, and the priority inbound flow answering a test number, booking into a sandbox and transferring to a person. Day 7 is the trial decision.
Month 1
Live on your main line
The agent takes a share of real calls on your number, with the recording disclosure, transfers into your team or contact center, calendar and CRM updates, and a dashboard of calls handled, booked and transferred.
Month 2
Outbound and Spanish
Reminder or follow-up calls with consent checks, Do Not Call screening and calling-hour limits, SMS confirmations on a registered A2P 10DLC campaign, and a Spanish flow if your callers need one.
Month 3
Peak volume and cost per call
Concurrency limits for your busiest hours, a review of cost per call across telephony, speech and model, a quality pass on transfer reasons, and the next location or campaign planned.

A dedicated voice AI developer vs a US voice AI agency, a platform you configure, or an in-house hire

	Empiric Infotech (remote dedicated developer)	Voice AI agency (setup fee and retainer)	Voice platform you configure (Vapi, Retell, Synthflow)	In-house engineer (US hire)
What you end up with	Agents in your own telephony and cloud accounts, with the developer still tuning them	An agent on the agency's stack, often billed per minute	A dashboard and agents you prompt yourself	Whatever your team can build alongside its other work
TCPA and recording consent	Consent checks, DNC screening, calling hours and state recording notices built in	Depends on the agency	Settings you configure and monitor	Yours to build
HIPAA calls	Telephony and models covered by BAAs; masked transcripts	Ask for the full BAA chain	Available on some plans	Yours to arrange
Integrations	Two-way with your CRM, scheduler and contact center, maintained	Built to the agreed spec	Whatever the platform ships, plus your own glue code	Built and kept working by your team
Cost model	A flat monthly fee per developer; call usage at cost on your accounts	Setup fee plus monthly or per-minute fees	Subscription plus per-minute usage	Salary at a $135,980 median for US software developers (BLS, May 2025), plus benefits
Time to start	48 hours	Days to weeks	Hours to set up, weeks to make it production-ready	Months of hiring
Paperwork	One USD invoice a month; W-8BEN-E provided	Per agency terms	A card subscription	W-2 payroll and payroll tax

The comparison describes how each option usually works, not any one provider. Per-minute telephony, speech and model costs apply in every option; with us they sit on your own accounts at cost.

Why US businesses use a dedicated developer for voice AI

Voice agents fail in specific, fixable ways: a caller talks over the greeting, a booking lands in the wrong location's calendar, a transfer drops the context, a model update changes how the agent handles an upset caller. Fixing those takes someone who listens to the recordings every week and knows the code. A platform alone leaves that work to your team, and an agency build often stops at launch.

A dedicated developer stays with the agent. In the Eastern morning you review yesterday's calls together and agree what to change, and the change is tested and live by the next morning. Hiring that person in the US means competing for engineers at a $135,980 median salary (BLS, May 2025) before benefits.

Everything runs in your accounts: your numbers, your Twilio or Telnyx project, your cloud, your recordings. You own the code from day one, pay one monthly USD invoice, and can stop with seven days' notice.
