Sentinel ensures service continuity by establishing external calls through the PSTN and by routing internal calls when the primary network is temporarily unavailable.

Network Demarcation

Create a clear separation between the enterprise’s and the operator’s networks by hiding the topologies and credentials, and by blocking unauthorised users.

Remote Users

Sentinel solves far-end NAT traversal problems and supports SIP manipulations, providing communication service access to branch offices, home workers, or travellers as if they were on the same site.

Legacy and IP Systems Integration

With its flexible configuration of FXS, FXO, and PRI telephony ports, call-switching, and user-defined call properties (including caller/calling ID), the Mediatrix Sentinel smoothly integrates legacy CPE into IP systems.
