I don't see how I would be able to since the broadband modem never came to NA so mine just has the dial-up one. Even if the tools linked here would work with dial-up, somehow: I don't have a landline to make the call. 😩
Edit: Needs a Raspberry Pi but doesn't need a landline. Interesting... Just need a raspberry pi and an RJ45 cable. $40-50 and I could play Chu Chu Rocket against other people again! 😃
