The Mediatrix unit uses digital certificates, which are a collection of data used to verify the identity of individuals, computers, and other entities on a network.
- the certificate's name
- the issuer and issued to names
- the validity period (the certificate is not valid before or after this period)
- the use of certificates such as:
- TlsClient: The certificate identifies a TLS client. A host authenticated by this kind of certificate can act as a client in a SIP over TLS connection when mutual authentication is required by the server.
- TlsServer: The certificate identifies a TLS server. A host authenticated by this kind of certificate can serve files or web pages using the HTTPS protocol or can act as a server in a SIP over TLS connection.
- whether or not the certificate is owned by a Certification Authority (CA)
Although certificates are factory-installed new ones can also be added. Since TLS certificates are validated in terms of time (certificate validation/expiration date, etc.), the use of NTP (Network Time Protocol) is mandatory when using the security features.
- Host Certificates: used to certify the unit (e.g.: a web server with HTTPS requires a host certificate).
- Others: Any other certificate including trusted CA certificates used to certify peers (e.g.: a SIP server with TLS).
- SipEp.InteropTlsCertificateValidation (also available in the DGW Web page under SIP/Interop)
The certificates must be uploaded to the Mediatrix units. They define how a Mediatrix unit will certify the remote host in order to mark it as secure and suitable for a TLS connection. If the Mediatrix unit does not trust the remote certificate (i.e. does not authenticate it with either one of the 3 methods: HostName, trustedCertificate, DnsSrv), then the Mediatrix unit will not establish the connection.
- for testing purpose,
- if one cannot identify the required CA cert, or
- the CA cert has mismatched Common Name/Subject Alternate Name. (In this case there is no fallback, it will fail if the name does not match)
- Configuration Web pages
- File transfers (scripts, firmwares, etc.) with HTTPS
- Configuration using TR-069
- Wired Ethernet Authentication with EAP (802.1x)
One common use of the host certificate is to allow https Web access to the unit (which in this case, the device is the TLS server.

Importing a Trusted CA or SIP Server Certificate to the Mediatrix Unit
- Go to Management/Certificates.
- ClickActivate unsecure certificate transfer.
- In the Certificate Import Through Web Browser table, from the Type selection list, select Other.
Click Browse and
select your certificate.
Note: The name of the certificate cannot have more than 50 characters.
- Click Import.

Importing a Host Certificate to the Mediatrix Unit
- Go to Management/Certificates.
- Click Activate unsecure certificate transfer.
- From the Type selection list, select Host.
- Click Browse and select the Host certificate.
- Click Apply
In the Host Certificate
table, select the services that Host Certificate should be associated
Note: A Host certificate is by default associated with all services. Several Host Certificates can be imported and associated with one or several services.
- Click Import.
- Click Apply.

Mediatrix units are supplied with an exhaustive set of documentation.
Mediatrix user documentation is available on the Media5 Documentation Portal at http://documentation.media5corp.com
Several types of documents were created to clearly present the information you are looking for. Our documentation includes:
- 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.
