How quickly can I set up an AI receptionist?
Setup is incredibly fast! Most businesses are up and running within 24 hours. Simply sign up for a free trial, forward your phone number to Gretta, customize your AI’s responses, and you’re ready to go. Our team provides white-glove onboarding for enterprise customers.
Can Gretta AI book appointments automatically?
Yes! Gretta AI integrates with popular calendar systems like Google Calendar, Calendly, and Cal.com. It can check availability, book appointments, send confirmations, and even send reminders via SMS – all automatically without any human intervention.
What happens if the AI can't answer a question?
Gretta AI is trained to handle complex conversations, but if it encounters something beyond its scope, it can seamlessly transfer the call to a human team member or take a detailed message with contact information. You maintain full control over escalation rules and fallback options.
Is my customer data secure with an AI calling system?
Absolutely. Gretta AI is 100% secure with enterprise-grade encryption, SOC 2 compliance, and GDPR-ready infrastructure. All conversations and customer data are encrypted both in transit and at rest. We never share your data with third parties.
Does it work for outbound calls and sales?
Yes! Our Outbound + SMS plan includes smart dialing sequences, cold and warm outreach campaigns, time zone intelligence, and automated follow-ups. It’s perfect for sales teams looking to scale their outreach without hiring more staff.
Can customers tell they're talking to an AI?
Most customers don’t realize they’re speaking with AI! Gretta uses advanced voice technology with natural speech patterns, appropriate pauses, and context-aware responses. Our 98% satisfaction rating shows that customers appreciate the instant, accurate service regardless of whether it’s AI or human.
