Sentinel 100 Pure IP | eSBC
for small IP PBX environments

session-based licensing starting at 2 sessions

The Sentinel 100 Pure eSBC is a high-performance Session Border Controller for SMBs targeting applications for up to 120 users.
The Sentinel 100 is a Session Border Controller designed for SIP normalization, network demarcation, availability and security. Tools for QoS monitoring, remote bulk management and troubleshooting for cost-effective network maintenance are the goal. It is a cost-effective solution to connect multiple trunk lines, branch offices and mobile workers to protect enterprise IP PBX and UC systems. The Sentinel also provides a firewall with DDoS prevention and encryption capabilities for maximum protection of signals, media and data.

eSBC update with Virtuo

Session Border Controllers thrive on being up to date. Gaps and attack scenarios need to be updated quickly and promptly in the firmware and SBC logic. With Virtuo support, Sentinel can regularly download the latest firmware versions and new defense rules (ruleset). denk-stein:net offers this service in cooperation with Media5. The subscription is optionally available. Furthermore, you can also install additional SIP licenses via Virtuo. The customer expands his gateway quickly and unbureaucratically. The remote support by Virtuo can be switched on and off individually in Sentinel-eSBC. The customer is thus always the master of the process. The Virtuo platform never takes the initiative on its own. Contact is always established by the customer SBC. This reduces the risk of an open remote interface.


Sentinel ensures continuity of service by establishing secure external calls over the PSTN and by routing internal calls when the primary SIP trunk is unavailable (optional).

Remote user

Sentinel resolves NAT traversal issues and supports SIP manipulation. It also secures access for branch offices, home workers or travelers.

Network demarcation

Establish clear separation between enterprises and provider networks by hiding topologies and preventing credentials from unauthorized users. Integrate legacy and IP systems with its flexible configuration of E1/T1 PRI, ISDN BRI, and FXS/FXO telephony ports (optional in the Sentinel 100 Hybrid version). Call transfer and custom call features are seamlessly integrated into the IP environment by the Mediatrix Sentinel.
