I am not trying to muddy the waters. The reason I asked is we are being told by Mitel Corporate that the sx2000 per nodes are not supported past release 6 and that we will have to make plans to move are all of our digital sets to IP and analogs to ASU II's. We are currently on Software Version 9.0.2.18 and looking into going to Release 6. If this is true we are looking at a huge overhaul.
