FAQ
Which voice platform should I use?
It depends on your budget, call volume and country. After a quick chat I'll recommend Twilio, Plivo, Retell or Gemini Live.
Do I pay for phone and AI usage separately?
Yes. Phone and AI usage are billed to your own accounts, so you keep full ownership. I'll help you set them up.
Can the agent connect to my CRM or calendar?
Yes. I've built Salesforce, Cal.com and webhook integrations, and I can scope other tools such as HubSpot or Google Calendar.
Can the agent answer questions about my business?
Yes. I build a knowledge base from your documents, website or FAQs so the agent answers accurately about your services.
