I would like to ask you, experts, if you can implement the functions of answering calls and sending text messages through nodejs. A phone is a virtual mobile phone on your computer. Thank you

This is more difficult. One is to use the network gateway, which requires you to have a relevant gateway at the operator; the other is to use the SIM module, which plugs in the SIM to connect the serial port or USB port (actually equivalent to a connection Computer mobile phone); another one is to connect the mobile phone with a data cable; control it through relevant software.
