This is a replica of the Duplex feature launched by Google in 2018 and revealed at Google I/O 2018. It has most of the features Duplex had, although now there is a workaround, since you cannot inject audio into phone calls in Shortcuts: using two devices, which are: 1. the device you are currently using and 2. another device, preferably a phone, which can make and receive calls.
