  No, it is not possible to rewrite From header field. There is another
  mechanism -- Remote-Party-ID header field. SER can add this header
  field and put user's phone number into it. Your PSTN gateway can then extract
  the phone number from the header field and display it as the caller's
  number.

  In the stable version of SER (0.8.11) the Remote-Party-ID header
  field works only with radius authentication (i.e. the phone number is
  obtained from a radius server). Obtaining the Remote-Party-ID from
  database is currently in unstable CVS branch only.
