Communication system, non-transitory computer-readable recording medium storing computer-readable instructions for registration mediating server, and non-transitory computer-readable recording medium storing computer-readable instructions for service providing server

摘要

A registration mediating server may send to a function mediating server a first authentication information request, receive from the function mediating server first authentication information, send to the function mediating server an execution information request, receive from the function mediating server specific execution information, and send to a specific server communication information including the first authentication information and the specific execution information. The specific server may register the communication information, receive from a sound input device a first function execution request, extract the first authentication information and the specific execution information, and send to the function mediating server a second function execution request including related information which is related to the extracted specific execution information by using the first authentication information. The function mediating server may send a function execution instruction to a function executing device by using the related information. The function executing device may execute a function.
