Despite being around for over 5 years, Signal has gained popularity in recent times due to the recent change in Whatsapp’s Terms of Service. If you have decided to switch to the privacy-focused messenger as well, you might have noticed that your VOIP conversations are also showing up in the native Phone app. If you want to opt out of this feature, simply follow the guide below.
How do I enable 'Show Calls in Recents' in the Signal app on iPhone?
