I will build ai voice agent for calls and appointment bookings

A phone number you can point at the agent (I can help you get one), a rough script of what a good call sounds like, and API keys for Vapi or Retell plus your chosen model. I'll walk you through setup if you haven't used them before.

You pay the platforms directly, on your own accounts, so you control spend. Roughly $0.07 to $0.15 per minute of call time across voice, model and telephony. A business taking 200 calls a month at three minutes each typically runs $40 to $90. I'll estimate yours before you order.

No. These use real-time streaming voices with natural interruption handling, so callers can talk over the agent like a normal conversation. I tune latency and turn-taking during testing, which is the part most builds skip.

Yes, included from Basic. Google Calendar, Calendly, Cal.com, or your CRM's booking system. The agent checks live availability and confirms the slot on the call, then sends a confirmation.

It transfers to a human or takes a message, rather than guessing. I build the escalation path deliberately, and you set the rules for when it hands off.

Yes, from Standard up. Follow-ups, appointment reminders, no-show recovery, lead qualification. Check your local regulations on outbound calling first, and I'll tell you what I can and can't help with there.

Yes. You get the full prompt, flow and config files, running on your own accounts. Nothing is locked to me. Voice agents benefit from tuning after real calls, so I offer a 30-day monitoring extra if you want me adjusting it against live transcripts.

Yes. Dograh is open source and I can deploy the entire stack on your own server, so you pay only for the model and telephony, with no per-minute platform fee on top. Everything stays inside your infrastructure, which also matters if you're under HIPAA, GDPR or local data residency rules.
