In Order to Authenticate a Caller on a Telephone Sufficiently

In order to authenticate a caller on a telephone sufficiently to make the conversation competent as evidence:

A) proof that the call came from a designated caller based on caller ID alone should be sufficient to allow the substance of the conversation to be introduced into evidence as having come from the person identified on the caller ID.
B) the person who received the call and who could identify the voice of the caller along with proof of the caller ID, should allow the substance of the conversation to be introduced into evidence.
C) so long as the caller identified himself or herself as being the particular person, whether or not the recipient of the call recognized the voice, such self-identification should be sufficient to make the evidence considered competent as evidence.
D) all of the above indicate that the conversation evidence should be considered competent and admissible into evidence.
