What do I need in order to monitor several lines?

For two lines you would require two voice modems that do not conflict with each other and which both have 100% TAPI compliant wave drivers.   For a more professional solution or for more that two lines we recommend a Professional Voice Cards.   See www.nch.com.au/ivm/modems.html for more information about uptodate information about hardware.
