I cannot find any details about Call waiting on GrapheneOS. It has become annoying when I am not notified of incoming calls while I am already on a call. Has anyone been able to turn on Call Waiting in GrapheneOS? Do I need to use a different Dialer app like Google's one to get it to work?
Edit: I went through all the settings of AOSP dialer and haven't found any settings related to Call Waiting.
Edit #2: Found the setting in AOSP dialer. It was under "Calling accounts" then my Carrier settings.
