FXO/FXS Analog Gateways

ZYCOO's dedicated FXO and FXS gateways connect analog telephony to your VoIP network — each as its own device. Choose 8-port or 16-port FXO gateways to bring existing PSTN lines into your SIP infrastructure, or 16-port and 32-port FXS gateways to connect analog devices to your VoIP network. Built on standard SIP with support for multiple audio codecs and QoS traffic management, each gateway is engineered for stability and scales from small offices to enterprise deployments.

PRI Digital Gateways

The PRI gateway connects your VoIP network to digital telephone systems over ISDN, converting a full E1/T1 trunk — supporting 30 voice channels over a single port — into standard SIP calls. Built for high-capacity environments like office buildings, hotels, and hospital facilities, it delivers enterprise-grade reliability without stacking multiple FXO ports to get there.
