Mediatrix C731 - 4x FXS + 4x FXO ports

Mediatrix C7 Series

The Mediatrix C7 Series offers a wide variety of configurations combining FXS and FXO interfaces for multiple applications in a single platform. It is available with 4 and 8 telephony ports and connects up to 8 analog phones, modems, or fax machines; or connects up to 8 PSTN or PBX trunk lines to an IP network.

The Mediatrix C7 Series VoIP adaptors are high-quality, cost efficient VoIP gateways connecting small to medium branch offices to an IP network, while preserving existing investments in analog devices and linking IP extensions with the PSTN for local toll services or survival scenarios.
