MMS Address Translation options

The sender’s carrier endpoint is used to provide logging and reporting details to the mobile operator and to identify the sender of infected content.

When MMS messages are transmitted, the From field may or may not contain the sender’s address. When the address is not included, the sender information will not be present in the logs and the unit will not be able to notify the user if the message is blocked unless the sender’s address is made available elsewhere in the request.

The unit can extract the sender’s address from an extended HTTP header field in the HTTP request. This field must be added to the HTTP request before it is received by the unit. If this field is present, it will be used instead of the sender’s address in the MMS message for logging and notification. If this header field is present when a message is retrieved, it will be used instead of the To address in the message. If this header field is not present the content of the To header field is used instead.

Alternatively, the unit can extract the sender’s address from a cookie.

You can configure MMS address translation to extract the sender’s carrier endpoint so that it can be added to log and notification messages. You can configure MMS address translation settings to extract carrier endpoints from HTTP header fields or from cookies. You can also configure MMS address translation to add an endpoint prefix to the extracted carrier endpoints. For more information, see Dynamic Profiles and Endpoints in the Authentication guide.

MMS Address Translation

Sender Address Source                Select to extract the sender’s address from the HTTP Header Field or a Cookie. You must also specify the identifier that contains the carrier endpoint.

MMS Address Translation

Enter the sender address identifier that includes the carrier endpoint. The default identifier is x-up-calling-line-id.

If the Sender Address Source is HTTP Header Field, the address and its identifier in the HTTP request header takes the format:

<Sender Address Identifier>: <MSISDN_value>

Where the <MSISDN_value> is the carrier endpoint. For example, the HTTP header might contain:

x-up-calling-line-id: 6044301297
