Frequently Asked Questions
What makes Answrr different from other AI phone answering services?
Answrr’s key differentiators are its exclusive use of Rime Arcana voice technology, which delivers the most natural, expressive AI voices available, and its long-term semantic memory that remembers every caller’s history, preferences, and past projects. Unlike generic AI systems that sound robotic, Answrr’s agents use emotional nuance, natural pauses, and dynamic pacing to build genuine relationships. The platform also features an AI onboarding assistant that builds your agent in under 10 minutes via conversation, eliminating technical setup. With triple calendar integration (Cal.com, Calendly, GoHighLevel), MCP protocol support for any business system, and real-time appointment booking, Answrr delivers enterprise-grade capabilities at a small business price.
Can Answrr handle technical questions from clients about structural projects?
Yes, Answrr can handle technical questions through its RAG (Retrieval-Augmented Generation) knowledge base. You can upload project specifications, engineering standards, or frequently asked questions in PDF, Word, or text format. The AI extracts key information and uses it to answer client inquiries accurately. For example, if a client asks about load-bearing wall requirements, Answrr can reference your uploaded documents to provide a compliant, brand-consistent response. This ensures that technical details are handled correctly without requiring human intervention for every query.
How does Answrr ensure client data security?
Answrr prioritizes security with enterprise-grade measures. All sensitive data—including call recordings, transcripts, and caller memories—is encrypted using AES-256-GCM, the same standard used by banks and government agencies. The platform uses role-based access control, ensuring only authorized team members can access data. Call recordings are stored in MinIO (S3-compatible) with configurable retention policies. Answrr is GDPR-compliant, allowing you to delete any customer data on request. No customer data is sold or shared with third parties, and your data remains yours—fully under your control.
Is Answrr suitable for large engineering firms with multiple locations?
Absolutely. Answrr supports multi-agent configurations, allowing you to create separate AI agents for different locations, services, or departments (e.g., a separate agent for residential vs. commercial projects). Each agent can have its own voice, knowledge base, calendar, and transfer rules. This enables consistent branding and tailored responses across all locations. With unlimited agents on the Pro plan and the ability to connect to any business system via MCP protocol, Answrr scales seamlessly with your firm’s growth, whether you have 5 or 500 team members.
What happens if a client wants to speak to a human engineer?
Answrr handles this seamlessly through smart call transfers. You can configure transfer destinations by department, topic, or caller request. When a client says, "I’d like to speak to a structural engineer," the AI recognizes the intent and routes the call to the appropriate team member. Before the transfer, the AI provides a full context handoff, including the caller’s name, project type, and key concerns, so your engineer is fully prepared. This eliminates the need for the client to repeat information and ensures a smooth, professional experience.
