I have the old 2000 as you suspect. And the 3 sx200's are at lw19r3 (different feature levels tho).
I have imat 126.96.36.199 installed at one 200 site, the pri card there connects ethernet.
188.8.131.52 at 2 others, their 200 pri cards only have the 10 cpn subs and connect serially, IMAT doesnt even show the ethernet connect option.
As the local computer with imat for the main site blew up, now, for the
2000, I load IMAT at the first 200 site, and connect over the vpn to the switch. Apparently this seems to be the correct imat version, as it doesnt complain about different database versions. (The version I was using on the old box always asked me to convert, ime, not a smart thing to do!).
I was just recently sent v 184.108.40.206 . Argh!!!!! I am just way to timid to try it on my 2000 as when I load the database, I get a message "The remote sites database is of an older revision. Some fields may not be applicable to this version. Select OK to continue loading or cancel to discontinue". Oh yay!
Am I right in assuming that I will probably want to use 220.127.116.11? Unfortunately, I have no original install discs and I'm not enough of a Windows geek to transfer installed software from one machine to another and make it work.
Perhaps theres an archive of wonderful Mitel stuff sitting on an old qnx box somewhere...
