Customers can order individual modules or a combination of them assembled from factory into a Sentinel base unit. By default Sentinel 400 is delivered with 3 SBC session licenses. Additional licences can be later uploaded for service activation. Sentinel also offers optional redundant power supply and 48 VDC unit.

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.

Sentinel SBCs are fully certified with Broadsoft softswitches.



  • 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.
