A captioning system includes an assisted user's communication system, including a display screen, a microphone, a speaker, an input device for specifying a calling number of a hearing user's communication device, and a processor linked to the display screen microphone, speaker and input device. The processor is programmed to perform the steps of: (i) upon entry of a calling number via the input device, scanning the calling number, (ii) identifying a type of the calling number; (iii) where the type is a first type, performing a first process to initiate a remote captioning service; and (iv) where the type is a second type, performing a second process to initiate a remote captioning service where the second process is different than the first process.
