The Yeastar P570 is the flagship on-premise PBX in the P-Series, built for enterprises and large call centres that need real capacity and high availability. Base capacity is 300 users and 60 concurrent calls — add the D30 expansion module and you scale to 500 users / 120 concurrent calls in the same chassis.
With Hot Standby failover and 12 module slots, it's the right platform for enterprises that can't tolerate downtime, NGOs running national support lines, and large contact centres.
