I’m looking for an affordable solution to get our Ethernet based controls on a standard analog telephone line (yes, stepping backwards). What I need is a router that will take outbound TCP/IP traffic and dial into a pc. It also must answer the phone line when the PC dials it up and pass traffic through to the Ethernet side.
It would seem that the PSTN modems and routers are quickly dying out. While we have found a few products, many of them are for the industrial PLC market and priced accordingly. Currently the Comtech PSTN router is what we are looking at. The cost of the device and shipping it here however is more than the controller we are connecting to it.
Anyone know of a similar device for a couple hundred bones or less?
