Using untrusted Wi-Fi to carry voice and video communication is an open opportunity for operators to extend volte/vilte services in, for example, indoor locations where cellular coverage may be spotty. Operators worldwide are currently launching ims-based voice and video calling over lte (volte and vilte) services, supported, for the moment, by about 70 commercially available mobile devices.
