One cannot have a sensible conversation with a person who claims that a document is a forgery, and at the same time claims it is not a forgery.
-----------------------------------------
You need to get your head seen to...
(1) the details of the 3:26am phone log were not disclosed at the time of the trial, but a copy was later copied onto the reverse of the 4:02am, log from the scene. In this respect, the document as a whole was a forgery, since you cannot have an original document on one side and a photocopy on the other...
(2) the original must have existed somewhere, but for some reason EP did not want to give access to it, possibly through fear that on the reverse it contained more information that the contents on the other side were provided to the police by Ralph Bamber...
(3) explanation at (1) above, document amounts to a forgery
(4) explanation at (2) above, proof that Ralph contacted the police (not a forgery)...
