The Yeastar P520 is built to integrate with modern business environments and supports SIP trunking, analog connectivity, and interoperability with a wide range of IP phones and ITSP providers. It also includes security and administration features such as TLS, SRTP, firewall, VLAN, QoS, and centralized PBX management capabilities through the Yeastar ecosystem.
Hardware-wise, the P520 uses a compact desktop chassis and provides 2 Ethernet ports, TF card support, and a 12V DC power input. Its small footprint makes it suitable for offices that need a dependable PBX appliance without dedicating rack space.
Overall, the Yeastar P520 is a practical and scalable SMB IP PBX for businesses that want a reliable phone system with unified communications features, modular telephony expansion, and flexible support for VoIP and legacy telephony connections.
