Frequently Asked Questions
Everything you need to know about getting started with Callisi
How quickly can I get started with Callisi?
You can get started surprisingly fast. After a free demo call, we build and train your personalized AI Phone Agent, set up all integrations, and run internal quality checks. Once everything is ready, we guide your team through a short kickoff and onboarding session. Most customers are fully live within just one week.
How exactly does a Callisi AI Phone Agent work?
Callisi connects to your existing phone system and automatically answers calls that are forwarded to your dedicated Callisi line — either always, after a delay, during peak times, or only after hours. The agent uses a deeply trained knowledge base tailored to your business and can integrate with your calendars, booking tools, and CRM to handle tasks like scheduling, account lookups, and order-related questions. If a caller needs a human, Callisi instantly forwards the call with full context. The result is faster responses, zero missed calls, and a consistent 24/7 customer experience.
3 Is Callisi GDPR-, HIPAA- and industry-compliant?
Yes — Callisi is fully GDPR-, HIPAA-, and industry-compliant, with data protection built into every step of the platform. We use industry-leading security practices, encrypted infrastructure, and only work with partners that meet strict compliance standards. Callisi and its infrastructure providers are SOC 2 Type II certified and offer full documentation and data processing agreements. If you have specific regulatory requirements, our team will guide you through them transparently.
Which businesses is Callisi suitable for?
Callisi is ideal for any business that relies on phone calls — especially those with high daily call volumes or many repetitive inquiries. It’s perfect for teams that miss calls, struggle with peak hours, can’t cover after-hours, or want to reduce receptionist workload and operational costs. Companies that depend on fast response times or handle time-sensitive requests benefit the most. If your team is overwhelmed by calls or you want to avoid hiring more staff, Callisi is an immediate game changer.
What does Callisi cost?
Callisi is more affordable than most businesses expect, with competitive pricing that includes full white-glove onboarding, setup, training, integrations, and ongoing support. Pricing varies based on your call volume, complexity, and software integrations, and typically consists of a small one-time setup fee plus a low monthly subscription. For many companies, Callisi replaces significant receptionist workload and can save tens or even hundreds of thousands per year. The best way to get an accurate quote is to book your free demo, where we assess your exact needs.
Is Callisi compatible with our existing software?
Yes — Callisi integrates seamlessly with your phone system and connects to over 500+ tools across scheduling, booking, CRM, patient management, POS, and more via secure APIs. We support both general-purpose and industry-specific platforms, depending on whether your software offers API access. If a direct integration isn’t possible, Callisi can still handle the full conversation and either send a booking link or forward the call with full context. This ensures you save time while keeping accuracy and human touchpoints where needed.
How reliably does Callisi understand accents, complex requests, or industry-specific terminology?
Callisi is powered by one of the most advanced language models available, enabling it to understand natural speech — including fast talkers, strong accents, dialects, and highly specific industry terms — with exceptional accuracy. Because your agent is trained on your own vocabulary and real customer scenarios, it becomes smarter and more precise over time. This leads to fast, natural responses, highly accurate intent recognition, and consistent performance 24/7. In short, Callisi doesn’t just hear words — it understands meaning.
What happens if the AI agent can't answer a question or a caller wants to speak to a human?
If Callisi encounters a question outside its scope or a caller asks for a human, it automatically forwards the call to the right number or arranges a callback. If no team member is available, Callisi collects the details and notifies your staff via SMS or email. All escalations are documented with transcripts and notes so your team can respond quickly with full context. This ensures callers never hit a dead end — just a smooth handoff between AI and your human team.
How does the Callisi dashboard help us measure performance and improve results?
The Callisi dashboard gives you clear, real-time insights into every call — including transcripts, recordings, AI summaries, and key metrics like call duration, lead connection rate, and missed-call recovery. It automatically captures new leads, organizes caller details, and shows exactly where your business is saving time and gaining revenue. You can also launch automated follow-ups and nurture campaigns directly from the dashboard. No other platform combines phone automation, deep analytics, and AI-driven workflows this seamlessly.
What kind of results can I expect within the first 30 days?
Most clients see immediate improvements: on average +15% more revenue (and up to +38% in call-heavy industries) simply because no calls are missed. Teams typically save 15–42 hours per week as Callisi handles scheduling, follow-ups, and repetitive questions. Customer and employee satisfaction increases by up to +73% thanks to faster responses and reduced stress. Overall, your business becomes more efficient, more modern, and far more competitive — often within the first month.
