Yeastar O2 (2 FXO) two-port analogue FXO module for Yeastar PBX systems.
The Yeastar O2 (2 FXO) is an expansion module providing two FXO (Foreign Exchange Office) ports for connecting analogue PSTN telephone lines to compatible Yeastar IP PBX systems. This module enables businesses to integrate traditional analogue trunk lines with their VoIP infrastructure, facilitating a smooth migration path or hybrid deployment.
Designed for use with Yeastar S-Series PBX platforms, the O2 module slots into the modular expansion bays, allowing administrators to scale analogue line capacity as required. Each FXO port connects to an external analogue telephone line from the local exchange or carrier, enabling inbound and outbound calling over legacy PSTN circuits.
This module is particularly useful for organisations that need to maintain existing analogue line contracts, connect to legacy alarm systems, or operate in areas where VoIP trunking is not available or reliable. The modular design of Yeastar systems ensures flexible configuration to match specific deployment requirements.
