PBX

Zadarma Cloud PBX is a fully-featured virtual phone system that lets businesses run professional call handling entirely from the cloud, with no physical hardware, wiring, or engineers needed to get started. Using an intuitive drag-and-drop configuration wizard, teams can build custom call flows, interactive voice response (IVR) menus, call queues, and time-based routing rules in as little as five minutes.

Core features include call recording, call transfer and forwarding, voicemail-to-email, and detailed call statistics and speech analytics for reviewing team performance and customer conversations.

The PBX integrates natively with leading CRMs — including Salesforce, HubSpot, Zoho, and Bitrix24 — as well as Zadarma's own free built-in CRM, Teamsale, so calls, customer records, and sales pipelines stay in one place.

It also connects with Zadarma's virtual numbers in 110+ countries, letting businesses establish a local or international presence without opening physical offices, and with per-second billing and unlimited plans starting from a few dollars per user per month.

More recently, Zadarma has layered AI Voice Agents on top of the PBX to handle inbound calls automatically — answering questions, qualifying leads, and booking appointments around the clock — making it a fit for startups, remote teams, support centers, and growing companies looking to modernize their phone systems without enterprise-level cost or complexity.
