You may try to get one and hook up two SDSL modems, but at least here in
Munich the Telekom does not sell those lines any longer.

Basically ISDN is a low latency network, that is why you do not
recognize any echo as with VoIP calls. Depending on the distance and the
network hubs in-between it should be well within a few ms, as long as
your provider did not already switched it to an All-IP network which
unfortunately is currently going on.

But you have to give it a try to know exactly under your circumstances.

p.s.: if the sites are within direct line of sight and only a few
kilometers, you may try a 5ghz wlan bridge as well.
