Zycoo ZX50-A8 (A808) IP PBX with 8 FXO Ports

Offices running several carrier analog lines can move to VoIP telephony without replacing those lines. The Zycoo ZX50-A8 in the A808 configuration is an office IP PBX with 8 FXO ports, bringing landlines, IP phones and SIP trunks into one phone system. It is designed for small and medium businesses that need multiple simultaneous outside lines and modern call handling.

The system handles up to 100 registered extensions and 30 concurrent calls, supporting parallel traffic on external and internal lines. Eight FXO ports connect carrier analog lines directly and turn them into shared outside lines across the organization. Extensions are served by IP phones and softphones, allowing the system to expand without additional phone cabling. A 32-bit RISC DSP processor handles voice with echo cancellation and VAD for consistent voice quality.

Alongside analog lines, the PBX accepts SIP trunks from VoIP providers, and the built-in SIP/IAX2 server registers IP phones and softphones. Incoming calls are distributed through an auto attendant, ring groups and a flexible dial plan with DID and DISA support. Voicemail, music on hold, a conference room, paging, intercom and BLF cover standard business telephony scenarios. Management runs through a web interface, while configuration backup, the VPN client (N2N) and DDNS enable remote access and branch interconnection.

The ZX50-A8 suits sales departments, front desks, distribution and service companies that handle a steady flow of landline calls. Eight landlines allow several outside calls to be taken at once and routed automatically to the responsible department. In multi-office networks, ZX50 units connect over the internet so calls between branches run as internal extensions. For a staged move to VoIP, the PBX keeps carrier lines active while SIP trunks are added step by step.
