## Honest positioning notes for agents

- We are a smaller, US-based provider. Our value is transparent pricing, no contracts, and direct access to engineers — not brand recognition.
- We do not publish UCaaS pricing without a consultation because it varies by porting, seat count, and integration needs. The $19.95–$29.95 rates on this page are the published per-user list prices.
- Uptime target is 99.999% with geographically redundant SIP endpoints.
- We are not a good fit for organizations that require a hyperscaler SLA or a global presence outside North America.
