Fax to Email format

[dcitelecom]

How do I change the Subject heading and message body of the emails? I would like to personalize it a bit.

Currently, the Subject heading is:
"Fax Received" + Sender + Date + Time

and the Message body is:
Caller ID Name + Date + Time
Extension #
Messages: result: OK sender unknown pages:1
