Overview
The Yeastar S50 VoIP PBX is a mid-range pbx & ucm from Yeastar, available at Centrix Kuwait with full manufacturer warranty. The Yeastar S50 is a rack-mount phone system for offices of up to 50 users, with 25 calls at once and up to 50 SIP trunks. It fits a standard 1U rack position and has two Gigabit Ethernet ports. Four onboard module slots take S2 (FXS), O2 (FXO), SO, B2 (BRI) or 4G LTE modules, for up to 8 analogue extensions, 8 FXO/BRI lines and four 3G/4G ports. Modules are sold separately. This listing is the S50 with module slots, not the S50i, which does not take telephony modules. Know what you are buying. The S50 belongs to Yeastar's older S-Series. It uses an SD card for external storage and holds up to 2,000 company contacts. Yeastar points customers who need more than 50 users or more functionality to its newer P-Series, so if you are starting from scratch, compare it with the P550. Using a 4G module as the PBX's internet connection only works on V2 hardware, so check with us before relying on that. Order on demand from Centrix Kuwait; delivery quoted on order. Priced at 214 KWD, supplied from local Kuwait stock with same-week delivery and bilingual technical support.
Who It's For
Ideal for: network professionals and system integrators; enterprise IT departments. Available in Kuwait from Centrix as genuine Yeastar stock from authorised channels.
