Connections made to the IP Multimedia Subsystem (IMS), for services such as + RCS, SMS over LTE, VVM (Visual Voicemail), VoLTE (carrier-based calls on 4G and higher), VoNR (5G) and VoWi-Fi are largely implemented by the OS via TCP/IP rather than by the cellular layer itself. This means there will be connections by the OS to carrier servers instead of being handled by cellular. GrapheneOS modifies carrier configuration so that toggles for disabling VoLTE, VoNR and VoWi-Fi are always available. We plan to provide more toggles to control these things in the future beyond making all the standard toggles - available.
