SBC SIP Trunking Configuration - Sentinel in the LAN
- The Sentinel unit is located in the LAN.
- Only port ETH1 of the Sentinel is used.
- The Sentinel unit is set as a Demarcation point.
- The Sentinel unit may or may not register to the SIP service provider.
- The Sentinel unit is located in the LAN, behind a Near-End NAT.

Important Information on NAT, Interfaces, and Ports
Since this scenario uses only one physical network interface (ETH1) for communicating both with the ITSP/Public Internet and the IP-PBX, different ports will need to be assigned to the signaling and media interfaces for the Sentinel to differentiate the traffic.
- On the ITSP/Public Internet side, port 5060 is used for signaling with the 20000-20999 range for media. The router/firewall will need to be set up to allow connections from the ITSP/Public Internet on these ports, and set up port forwarding to the Sentinel internal IP address.
- On the IP PBX side, port 5064 is used for signaling with the 21000-21999 range for media. Depending on the PBX, this can be accomplished by either creating a SIP trunk on an alternate port, or in the Outbound Proxy configuration.

DGW Documentation
Mediatrix devices are supplied with an exhaustive set of documentation.
Mediatrix user documentation is available on the Media5 Documentation Portal.
- Release notes: Generated at each GA release, this document includes the known and solved issues of the software. It also outlines the changes and the new features the release includes.
- Configuration notes: These documents are created to facilitate the configuration of a specific use case. They address a configuration aspect we consider that most users will need to perform. However, in some cases, a configuration note is created after receiving a question from a customer. They provide standard step-by-step procedures detailing the values of the parameters to use. They provide a means of validation and present some conceptual information. The configuration notes are specifically created to guide the user through an aspect of the configuration.
- Technical bulletins: These documents are created to facilitate the configuration of a specific technical action, such as performing a firmware upgrade.
- Hardware installation guide: They provide the detailed procedure on how to safely and adequately install the unit. It provides information on card installation, cable connections, and how to access for the first time the Management interface.
- User guide: The user guide explains how to customise to your needs the configuration of the unit. Although this document is task oriented, it provides conceptual information to help the user understand the purpose and impact of each task. The User Guide will provide information such as where and how TR-069 can be configured in the Management Interface, how to set firewalls, or how to use the CLI to configure parameters that are not available in the Management Interface.
- Reference guide: This exhaustive document has been created for advanced users. It includes a description of all the parameters used by all the services of the Mediatrix units. You will find, for example, scripts to configure a specific parameter, notification messages sent by a service, or an action description used to create Rulesets. This document includes reference information such as a dictionary, and it does not include any step-by-step procedures.
