AI Voice Agents and Phone Receptionists for Service Businesses
We build custom phone receptionists and voice assistants that answer incoming calls, qualify leads, and book appointments directly into your calendar. Our voice agents speak natural English, Spanish, Urdu, or Arabic, handling customer questions without leaving callers waiting on hold. Every agent integrates with your CRM, booking software, or phone system so your staff can focus on the job.
A good fit for
Who it's for.
- Medical and dental clinics that miss after-hours patient inquiries and appointment requests.
- Salons, spas, and wellness studios spending hours scheduling and rescheduling client visits.
- Home-service contractors (HVAC, plumbing, roofing) who lose emergency job leads while out on site.
- Businesses serving multilingual client bases who need clear voice coverage in English, Spanish, Urdu, or Arabic.

FAQ
Straight answers.
How does pricing work?+
We charge a fixed price per project covering prompt engineering, telephony setup, and API integrations. You pay telephony and voice model providers directly at their standard rates.
How long does it take to launch a voice agent?+
A typical voice agent project takes two to three weeks from kickoff to live deployment. You will be able to dial in and test the agent at the end of week one.
Who owns the voice agent and prompts?+
You own everything. The prompt instructions, telephony configurations, webhook code, and platform accounts remain 100% in your ownership.
Which tools and subscriptions will we need?+
You will need an account with a voice platform (such as Retell AI or Vapi), a telephony provider like Twilio, and access to your scheduling tool or CRM.
What happens when a caller has an emergency or wants a human?+
We build deterministic transfer rules. If a caller requests a person or reports an urgent issue, the agent transfers the call immediately to your staff's mobile or desk phone.
