I came across this thread as I was looking for another answer, so I thought I would throw in my $0.02:
1. If you're interfacing with InnQuest Software's roomMaster 2000, you DO NOT need an iPocket or similar adapter. The interface can be done directly through IP. Check out
www.innquest.com. 2. InnQuest's PMS trainers/installers are shown how to interface with Mitel FIRST, since that is found in at least half of the hotels where InnQuest's PMS is installed.
