In short

Liftup Technologies builds AI voice agents for US businesses, working remotely from India, with an office in New York. The agent answers inbound calls, qualifies the caller, books on your calendar, texts a confirmation and logs the call in your CRM. We design disclosure, recording consent and escalation around TCPA, state recording laws and FTC rules. You receive a fixed quote within one working day of a short call.

Who buys voice agents in the US

The US market is large and the buyers are practical. Home-service companies, dental groups, law firms, property managers and auto dealers each take thousands of calls a year, and each knows roughly what a missed call costs. They do not want a demo of a talking robot. They want the phone answered, the job booked and the lead in the CRM before anyone is back from the job site.

That shapes how we build. We begin with a few weeks of inbound calls, because inbound is the lowest-risk and highest-return starting point. Outbound calling is possible but runs into stricter federal and state rules, so it is a separate scope.

BusinessCalls the agent handlesSystems it connects to

Dental and medical groupsNew patient and reschedule callsScheduling system, with care over health information
Law firmsIntake: matter type, conflicts check detailsCase or CRM software
Property managementMaintenance requests and showingsWork-order tools and calendars
Auto dealersService appointments and sales leadsDealer CRM

Seasonality matters as well. A roofer in Florida sees call spikes after storms, an HVAC firm in Texas after a heat wave, and a tax preparer in April. We build overflow rules so the agent copes with a spike by taking details and promising a call-back window, instead of leaving callers on hold.

Rules we design around

There is no single US voice-agent law. The rules come from several places, and they differ by state. We flag these on the first call so nothing surprises you later. None of this is legal advice, and your counsel should approve the final wording.

  • Telephone Consumer Protection Act: the FCC has treated AI-generated voices in robocalls as artificial voices, so outbound calls generally need prior express consent. We keep launch scope to inbound unless consent is documented.
  • FTC rules: the Telemarketing Sales Rule and the National Do Not Call Registry apply to sales calls. Claims the agent makes must be true and supportable.
  • Call recording: several states, including California, require all parties to agree to recording. We open each call with a notice so one script works nationally.
  • State privacy laws: California and other states give callers rights over their data, so retention and deletion are designed from the start.
  • Health and finance: HIPAA or GLBA may apply. We keep protected data out of transcripts unless the right agreements are in place.

The FTC publishes its telemarketing guidance, linked below.

Time zones and the US working day

Pune is 9.5 to 10.5 hours ahead of the US East Coast and 12.5 to 13.5 ahead of the West Coast. That sounds awkward, but it works well for a build. You describe a problem at the end of your day, and the fix is waiting when you start the next morning. Live calls with you happen at your early morning, which is our evening. Our New York office handles US-hours coordination.

Your agent itself is not tied to either time zone. It runs around the clock and follows your business hours and holiday list, including regional holidays such as Juneteenth.

How a build runs

  1. Call auditWe study recent calls and list what callers ask for, what goes wrong and what each call is worth.
  2. Design and approvalWe write the script, escalation rules and recording notice. You approve before any build starts.
  3. Build and connectWe set up the number, calendar, CRM and logging, with a text confirmation to the caller.
  4. Test with accentsUS callers range from Boston to Houston to Seattle. We test across accents, noise and interruptions.
  5. Launch and tuneWe start with overflow and after-hours calls, review transcripts weekly and widen the scope.

Pricing

Projects start at $1,500, with extra work at $30 an hour. Price rises with call types, integrations and the number of live transfers. Telephony and speech charges are billed to you by the providers and depend on minutes. The AI voice agent cost guide shows typical ranges, and the voice agent service page lists what is included. For a related build see AI automation for US businesses, which takes the call data into your back office.

Questions, answered

Do I need consent to use an AI voice on calls?
For inbound calls, a clear disclosure and recording notice at the start covers most cases. For outbound calls the rules are tougher and consent is usually required, so we scope outbound separately and with your counsel.
Which phone systems does it work with?
We can connect agents to common VoIP and telephony providers using call forwarding or SIP. We confirm compatibility with your setup during the first call.
Can it work in Spanish?
Yes. Spanish is a separate flow with its own script, reviewed by a native speaker on your side. It adds to the price.
How fast can we launch?
A single inbound line usually launches in three to five weeks including testing. Multiple locations or systems take longer, and the quote says so.
Who owns the agent?
You do. Accounts, scripts and code are set up in your name, with a handover guide.
