Yeastar B2 module BRI S-Series / P-Series PBX Card / Module

The Yeastar B2 Module BRI is an ISDN Basic Rate Interface expansion module designed for Yeastar IP PBX systems. This module provides two BRI ports, enabling connection to ISDN trunk lines or ISDN terminal equipment, allowing businesses to integrate traditional ISDN telephony services with their VoIP infrastructure.

The B2 module is intended for installation in compatible Yeastar S-Series and P-Series PBX systems that support modular expansion. It enables organisations to maintain existing ISDN connections while transitioning to IP-based telephony, making it suitable for sites where ISDN services remain in use or where gradual migration is required.

As ISDN services are being phased out across the UK and Europe, this module serves an important role for businesses that still rely on BRI connections during the transition period to all-IP networks. It provides a practical solution for hybrid telephony environments.
