Wouldn't it be nice if your cellular provider had a SIP gateway for your number as well, and if it rang your phone it would also route to your SIP device? Like

Like, it's already routing calls through the WiFi. Is it really that much harder for them to allow two devices to register for the number and connect the first to answer?
- lxgr 3y agoMy German mobile phone provider supports that! It's really handy when traveling internationally; I usually receive my calls over SIP without incurring any roaming charges (due to using a local SIM). In the US, Google Voice allows a conceptually similar thing (but you need to give everybody your Google Voice number or port your "real" number there; then you can forward calls to both a mobile and a SIP number, with both ringing for incoming calls).
