Can anyone help me here. What physical hardware, make and model can I buy, prefferably not too expensive, that will convert a standard POTS system to VOIP and then back again. Basically I need to send pots over a VPN, in order to do this I first need to take the handset, connect it to a box that converts it to VOIP (IP) connect it to my hardware VPN (dont worry about the VPN side, I have that covered) then at the other end, out of the VPN into the ASterisk system which will also have another VOIP box converting the receiving end POTS.
I purchased 2 Linksys PAP2T but neither will communicate with asterisk, irrespective of how asterisk is configured, and Linksys nor this forum are willing to assist in getting it working, apparenlty its not supported.
So what hardware is supported, that is easy to purchase and not expensive?
