Frequently Asked Questions

Will this work with my existing UK phone numbers?▾

Yes. Port your DID to Amazon Connect or use a Voxflow-issued UK DID (Enterprise). Exact DID routing guarantees zero cross-tenant leakage.

How does Google Sheets sync work?▾

Connect a sheet from Dashboard → Settings. Every call outcome and tool edit is mirrored live to your Call Log / Email Log tabs via a per-tenant service account.

What about GDPR & UK Data Residency?▾

Call records and data stay in AWS London (eu-west-2) with transcript auto-purge on your retention schedule. Live inference transits Groq's hosted API and one legacy number routes outside London — both disclosed at /privacy. DSAR export/erasure is one click.

Can I try before purchasing?▾

Yes. Every account starts with a 14-day trial with 30 live telephone minutes and unlimited dashboard simulator. Card collected, £0 today, billed Day 14 unless cancelled.

What happens when the agent can't resolve a call?▾

The call is escalated per your rules with the transcript and context attached — nothing vanishes. There is no 24/7 human SLA unless your Enterprise order form contracts one.

How do included minutes and overages work?▾

Starter includes 250 call minutes a month, Growth 1,200; Enterprise is contracted. Overage is billed per minute per your order form, and metered usage is visible in your dashboard.

Can I cancel anytime?▾

Yes — cancel in the Stripe customer portal and service runs to the end of the paid period. Trial cancellations before Day 14 are never charged.
