It's ashame Avaya will no longer support magix, it's a nice medium size phone system. Not all buisnesses have $$$ for IP, or want to go that route. I still see older busnesses that have, and love, there merlin II, with BIS10 handsets, and do NOT want to upgrade to magix or parner. Plus Magix is a very stable system, the only BAD Magix cards I frequently came accross are the ETR016.
