Product Overview
Designed specifically for enterprise applications, the Mediatrix 4400 digital gateways make use of existing broadband access equipment to connect to any standards based VoIP network.
The Mediatrix 4400 digital gateways meet the requirements of enterprises that want to connect their ISDN equipment, such as PBXs, through a BRI interface to an IP network or as a gateway to the PSTN.
Mediatrix 4400 digital gateways provide transparent ISDN port extensions over an IP network. The remote ISDN terminals can be managed centrally and benefit from PBX services such as calling groups and voice mail.
Applications
The Mediatrix 4400 digital VoIP gateways allow any office to use an existing IP network for lower-cost voice communications.
The Mediatrix units link any standard ISDN BRI connection to the IP network and deliver the clarity of toll quality voice for a comprehensive VoIP solution.
T.38 FoIP, fax bypass, and modem bypass capabilities ensure that the Mediatrix 4400 digital gateways seamlessly transport voice and data services. The Mediatrix 4400 digital gateways offer flexibility and scalability for VoIP network integration and low bandwidth voice.
With configurable NT/TE BRI ports, call-switching and user programmable call routing (including caller/called ID), Mediatrix 4400 digital gateways integrate smoothly into existing PBX and PSTN networks.
