Mediatrix Sentinel 400

The Sentinel 400 bundles the capabilities of a Session Border Controller and a Media Gateway. Robust, field-upgradable, and ready for third-party software integration, this multi-service business platform is designed for medium and large enterprises. Sentinel 400 is ideally targeting applications for up to 2000 users.

The Sentinel 400 delivers a flexible architecture designed to address a variety of applications including security, demarcation point, SIP normalisation, and survivability.


The Mediatrix Sentinel ensures the quality of service by establishing calls through a secondary server or through the PSTN when the primary server is temporarily unavailable.

Network Demarcation

Sentinel monitors the quality of service and provides enhanced troubleshooting tools to understand and resolve failures affecting the service.

SIP Normalisation

The Mediatrix Sentinel normalises SIP signaling protocols supported by vendors into a single well-defined interface that can be adapted to any specific IMS or Softswitch implementation.

Integration with Third-Party Applications

Sentinel provides an open environment for system integrators to bundle their own applications into a business-class multi-service platform, optimising CPE investment while addressing the complete solution for customer needs.
