258 Mediatrix 4104
You cannot set this field to an empty value. Furthermore, it is reset to 333000X during a factory
reset, the X digit being the port number.
4. Set a display name in the sipUADisplayName variable.
This is a friendly name for the user agent. It contains a descriptive version of the URI and is intended
to be displayed to a user interface.
5. Define a list of other accepted user names in the sipUAOtherAcceptedUsernames variable.
This is a list of user names that the endpoint recognizes as its own, but does not register in contacts
sent to the registrar. The endpoint only registers the user name in
sipUAMainUsername .
You can use this variable to add variations on the main user name. For instance, let’s say that the
main user name is a telephone number, 555-1111. Variations could be to prefix the local area or
country code, such as 819-555-1111.
To include more than one user name, separate them with a “,” character, such as: user1, user2,
5552222, 18195552222.
6. Restart the Mediatrix 4104 so that the changes may take effect.
Home Domain Override
You can override the home domain configuration. The address of record in the REGISTER uses this string
instead of the SIP domain as set in the
sipDomain variable (see “User Agents” on page 257 ) or home domain
proxy host (variable sipHomeDomainProxyStaticHost variable (see “Proxy Server” on page 165 for details).

To override the home domain configuration:
1. In the sipInteropMIB , set the sipInteropRegisterHomeDomainHostOverride variable with the proper
IP address or domain name.
SIP User Agent Header
The User-Agent header field contains information about the user agent client originating the request. For
instance, the information of the User-Agent header could be something like the following:
User-Agent: Softphone Beta1.5
You can specify whether or not the Mediatrix 4104 sends this information when establishing a communication
and customize the header value.

To enable sending the SIP User Agent header:
1. In the sipInteropMIB , set the sipInteropSendUAHeaderEnable variable to enable .
2. Set the sipInteropUAHeaderConfig variable with the proper macro.
The following macros are replaced by their representation:
• %version% : Version of the application.
• %mac% : Unit MAC address (lowercase).
• %rev% : Hardware revision number.
• %product% : Product name.
• %% : A '%' sign.
3. Restart the Mediatrix 4104 so that the changes may take effect.
