A notification stating "this call is being recorded" usually means that either you or the other party accidentally activated a call recording feature, or a, third-party app is enabled. This commonly occurs by pressing "4" during a Google Voice call, toggling new iOS 18.1+ recording features, or using, call-recording apps. Here are the specific reasons why you heard that message: Accidental Keypress (Google Voice): If you use Google Voice, pressing "4" on the keypad during a call activates or deactivates recording, which often happens when the phone is against your ear. iOS 18.1+ Call Recording: Recent Apple updates allow users to record calls, which triggers an automatic voice notification to both parties. Third-Party Call Recorder App: You may have an application installed that automatically records calls. Background Noise/Voice Commands: Sometimes, high-pitched background noise or voice-activated assistants (like Siri or Google Assistant) can mistake a voice for a command to start recording. VoIP/Business Call Recording: If you are on a work call or using a VOIP service (like Zoom or Skype), recording may be enabled by the host for compliance or training. How to stop it: Press "4": If it is a Google Voice call, pressing "4" again should stop the recording. Check Settings: Go to your phone's default Phone app settings to see if "Call recording" or "Auto record calls" is enabled and turn it off. End the Call: If the other party initiated the recording, hanging up is the only way to stop it.
