I will be going to Germany in November to do the IT side of a Christian leadership convention. I've been told I will have 3 ISDN lines (1 for video/audio streaming, 1 for to monitor webcams at other sites, and 1 for some other purpose that escapes me atm). I've never worked with ISDN lines and was hoping someone could give me an idea of what equipment I need in order to make them work.
