ZYCOO 4BRI, BRI Module, 4-Port ISDN

The ZYCOO 4BRI BRI module fits a compatible CooVox IPPBX chassis with four ISDN BRI ports, bringing legacy digital ISDN trunk lines onto the SIP-based system without needing a full PRI trunk's extra capacity. It is the base card in ZYCOO's BRI range, alongside the revised 4BRI-V2 built for the U80 and U100 models specifically. It suits a site still billed on ISDN BRI trunks rather than SIP or PRI. Dubai contractors can request a quotation by part number.
