So I'm trying to purchase some ISDN PRI phones. Preferably for E1/EuroISDN networks, but I can't seem to find any. I've been googling for days and all I can seem to find are ISDN BRI phones and VOIP systems. The only PRI related products I can find for sale are trunking cards.

Did anyone actually make PRI/E1 terminals. I have a few old H.320 videoconferencing phones, but they utilize strange interfaces and it will require a lot more research / work to get them working. Ideal I'd like some simpler PRI phones for this project to play with? Did such phones ever exist? Where can I purchase them or at least what manufacturers should I look for?
