Build your own dial-up ISP in 2019
This article came at just the right time.
Maybe the HN crow can help me with this one.<p>I have a lot of old hardware that i want to connect to the to my network. Most of them have a 56k modem the rest a 14/28k modem. What can i use to bring them all online at the same time. I tough to use some voip adapter (from pots to ethernet) but from what i understand there are not good for modem/fax style signal, also i need something that can handle at least 8 client at the same time (the number of computer to connect is 22 at the time but i don't know how realistic is to connect all of them at the same time using this method).<p>When i searched (i couple of month ago, so i might get wrong some terminology) i only found some enterprise pbx that were awfully expensive (1000$) i hope for something more cheap. I didn't find anything that work.
EDIT: Also i'm not sure how to understand if the hardware that i plan to use can do what i need. What do i need to look in a pots to voip converter to work as modem "server".
If i sound confused is because  i am.<p>I have a plan B, that consist of using serial port and emulate old style Hayes modem by a central more powerful (and modern) computer using a lot of usb2serial adapter, but i would rather avoid that since some computer have only 1 serial port and is already used for other hardware forcing me to choose between connectivity and the other device. Also some of the hardware it's not compatible with serial modem.
I've already test this approach and (expect the aforementioned shortcoming) it works quite well.<p>Thank you all in advance
