The customer facing location, although fixed, is a long way from our existing phone sockets so installing extra phone cabling is a hassle we don't want. We ran ethernet cables to there last year so have internet access already.
Our bank are telling us we need to use their choice of ISP (Europacom) to use an ip based chip and pin terminal.
1. Would I be able to use a voip phone adapter to connect a plain old PSTN chip and pin terminal so it can dial out over a voip network?
2. Would the adaptor be able to cope with the encryption the machine would likely use?
3. Are there security issues with this approach?
