Mediatrix 1204Four-port FXO Analog Gateway

Product Overview:
The Mediatrix 1204 provides PSTN access for various VoIP endpoints such as IP phones, FXS devices, softphones and IP-based PBX and Key Systems. It is an efficient solution to maintain local PSTN breakout in remote locations that are converted to IP.

By connecting CO lines from selected sites to a VoIP network, the Mediatrix 1204 enables service providers and enterprises to use a VoIP connection between pre-determined local networks.

The Mediatrix 1204 provides a web interface, giving users a convenient access to the unit for initial set-up. The devices can also auto-provision by fetching their encrypted configuration from a TFTP or HTTP server making installation secure and transparent to the end-users. To further facilitate deployments, factory loaded configurations are possible.
