FAQ

The free 30-day pilot questions, answered

The questions buyers ask most often before they sign.

What does the free 30-day pilot include?
A dedicated phone number, a production AI voice agent in your chosen vertical, 100 trial minutes, the full function-tool set for that vertical (a baseline of 14, more on some verticals), full transcripts and analytics, and email support. No credit card required.
How does sign-up work — is it self-serve?
Pick your vertical and submit your name, company, work email, and phone. We provision a dedicated trial number and email you the details, usually within one business day. From your dashboard you can then edit prompts, voices, and tools yourself.
Can I use my own phone number?
Yes. You can forward your existing number to the trial agent or port it later. Most pilots start on the dedicated CallSphere number and switch to your own number within the first week.
What happens at the end of the 30 days?
Nothing automatic. The trial agent pauses. You can convert to Starter ($149/mo), Growth ($499/mo), or Scale ($1,499/mo), or walk away. Your transcripts and call data remain available for export for 30 days.
Can I customize the agent during the pilot?
Yes. Edit the system prompt, swap voices, enable or disable tools, and upload a knowledge base (PDFs, DOCX, or plain text). Changes go live in seconds.
Do you offer the pilot in languages other than English?
Yes. All 57+ languages are available on trial agents. Spanish, French, German, Mandarin, Hindi, Arabic, and Portuguese are the most commonly requested.
Is the pilot HIPAA-eligible?
Yes for healthcare verticals. CallSphere is HIPAA-compliant: we sign a BAA at the start of the pilot, redact PHI from logs by default, and route calls through HIPAA-eligible infrastructure.
