You could find out if a regular rj-45 connector would fit in the dectalk by trying it. You may have to break the tab off. Since a cable isn't that expensive it wouldn't be a high cost experiment, but you would still have a cable subject to falling out. As for if it would work, it most certainly would work fine. My company uses cat5 cable for 19600 baud serial link all the time. A flat cable also works for the application. But the cable shape and the connector have nothing to do with each other really.
