Surely for a phone to receive calls, the provider has to know whether it supports VoLTE? How else would the carrier know how to connect the call?

- daveoc64 2y agoThe phone would have to actively make an IMS connection to use VoLTE, so the network would know when the device connects.
- kalleboo 2y agoThe problem is there are phones that can make and receive normal VoLTE calls, but when and only when you make an emergency call, it drops down to 3G, since it doesn't know how to signal emergency QoS on the network for VoLTE calls. There are no incoming emergency calls.
