"Maximizing Privacy: Essential Twitter Call Settings You Need to Adjust"
X (formerly Twitter) has introduced audio and video calls for all users, with default settings allowing anyone you follow to make calls to you. To avoid unwanted calls, users should adjust their settings by accessing the Twitter app, tapping the envelope icon, clicking the settings cog, and unchecking the "enable audio and video calling" box. Users can also choose who can call them and enable "Enhanced call privacy" to prevent their IP address from being revealed to callers. It's important to note that the calls are only available in the X app for Android and iPhone, and there is no mention of encryption for the calls.
