We don't have the actual transcript, actually. That has been locked away in a secret server, for some reason.
What we actually have is this:
"CAUTION: A Memorandum of a Telephone Conversation.· (TELCON) is not a verbatim transcript of a discussion. The text in this document records the notes and recollections of Situation Room Duty "Officers and-NSC policy staff assigned t_o listen.and memorialize the conversation in written form as the conversation takes place.

But even without the full and exact transcript, the stuff the White House released is pretty damning in itself. Though Trump doesn't seem to realize that.
