What can call-history records show?¶

They can record a call-related event, participants, direction, time, duration and state, but not automatically who spoke or what was said.

Keep the communication system visible¶

Native phone, internet app, cloud, notification, provider and participant-device records have different coverage. An outgoing attempt is not necessarily answered; a missed incoming alert does not prove awareness; a longer answered state supports connection without identifying the speakers. Zero duration also depends on the system's convention.

Reconcile the event layers¶

Compare account/SIM, local call state, network or app-provider signalling and the other participant's record. Small time and duration differences may reflect different event stages. Cloud history can synchronise to several devices, so device-specific evidence and human attribution remain separate.
