When will Optus allow VoLTE access from phones not sourced from Optus? Surely as VoLTE is a standard it can't be that hard to provide the SIP settings? If you want to make sure that customers don't use the settings inappropriately then bake them into an app that we can install. I'm not interested in hacking the service. I just want to keep on the LTE network, even when I'm on a phone call.
