The Mediatrix digital VoIP gateways are intelligent gateways combining cost-effectiveness and flexibility with high functionality and performance. They provide up to 60 simultaneous calls from the IP network or the PSTN.

The Mediatrix 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 or T1/E1 PRI connection to the IP network and deliver the clarity of toll quality voice for a comprehensive VoIP solution. The Mediatrix digital gateways tunnel ISDN/QSIG call signaling messages for full-featured PBX networking over IP.
