VoIP telephony for teams

Quo is the brand under which the well-known OpenPhone has operated since 2025: a cloud phone system built for small and medium businesses, now expanded with Sona, an AI voice agent that can answer calls autonomously.

Three plans per user/month with a 7-day free trial: Starter from $15 ($19 monthly), Business from $23 ($33), and Scale from $35 ($47), all with annual billing discounted versus monthly. Sona (the AI agent) includes 1,000 automation credits on every plan, with an additional per-call cost if that limit is exceeded.
