Adding to your “how the law would look at this kind of evidence in light of the possibility of fabricating it--that really depends on the jury”: making the case that the evidence was fabricated would probably not be too difficult looking at the accused’s normal call patterns (from which this “night of the crime” will probably deviate), no incoming calls (or worse; a missed incoming call), testimonies from the people called by the accused at the night of the crime, asking questions about the alleged conversation etc. For a fake alibi, making fake calls at the night of the crime is probably not the best option.
