How call billing works
We round up to the nearest minute. A 5-second call costs 1 minute. A 61-second call costs 2 minutes. This is how telephony billing works — each call has setup costs (voice synthesis, transcription, phone routing) we cover regardless of length.
What that means in practice:
- Most calls (1–3 minutes): you pay exactly what you'd expect.
- Short hang-ups and wrong numbers: $0.24 each.
- Long calls (5+ minutes): $1.20+ per call.
Most pilots spend $50–200/month on usage during the trial.

Pricing questions
How does the 30-day platform-fee waiver work?
For your first 30 days, you don't pay the $39/month platform fee. You only pay for the calls and SMS your AI handles, plus $1 to activate your first phone number. Starting day 31, the $39/month platform fee kicks in. You'll get an email reminder a week before your first $39 charge.
Why is the first phone number $1?
We charge $1 to activate your first number for two reasons: (1) it ensures we have a valid card on file for your usage charges, and (2) Twilio bills us for each number we provision. Starting your second month, the number is $10/month — the standard rate for additional numbers too.
Why are calls rounded up to the next minute?
Each call has fixed costs (voice synthesis, transcription, phone routing) that we cover regardless of length. Rounding up to the nearest minute is industry-standard for telephony — it's how Twilio, RingCentral, and traditional answering services all bill. A 5-second call costs the same as a 60-second call: 1 minute.
What does a typical month cost?
Most pilot tenants spend $50–200/month in usage during the trial:
• Small business with light call volume: $60–100/month total
• Medium service business: $150–250/month total
• High-volume outbound campaigns: $400–600/month total

What if I run out of wallet balance mid-call?
Your AI completes the call. The wallet shows red in your dashboard, you get an email, and you top up. Calls don't get cut off — but a low wallet will pause new outbound campaigns until you reload.
Is there a long-term contract?
No contract. Cancel anytime. Your unused wallet balance stays in your account while it's active. If you cancel mid-month, you keep the rest of the month's service (we don't refund partial months).
Can I get a refund?
Wallet balance is refundable if we initiate cancellation. Otherwise unused balance stays in your account while it's active. Email hello@castglobe.com to request a refund.
What if my AI gets stuck or makes a mistake?
One-click pause your AI globally from the dashboard (1h, 4h, until-tomorrow, or manual). Voicemail fallback kicks in. You can also intervene live on a call. Mistakes never charge — failed calls (under 1 second) aren't billed.
