The SX-200 ICP MD announcement goes back WELL over a year ago. What Mitel enforced a year ago was the "End of New Sales as of July 31, 2021." That quote comes from the updated MD announcement. This means Mitel stopped permitting new system sales as of July 31, 2021. The SX-200 ICP MD announcement was announced several years before that. I recall Mitel informing us in 2008 that the SX-200 ICP would be MD'd. The SX-200 ICP MD announcement has been the longest MD announcement in history (literally).
Many disliked the SX-200 and SX-200 ICP. I tended to like it. Real Canadian telecom engineering. As for the ICP variant of the SX-200 family, the SX-200 ICP was one of the smartest IP ("hybrid" if you want) integrated communications platforms (ICP) ever conceived. Just needed SIP station and SIP trunking added to it and it would have been perfect. In some cases, better than the MiVB/3300 ICP. Then again, you do that (add SIP to the SX-200 ICP), and it's WAY TOO close for comfort to the MiVB software (in terms of functionality, not necessarily programming - I will give the MiVB points for programming over the SX-200 ICP).
Actually, now tat I think about it, the "original replacement" for the SX-200 ICP was the Mitel 5000 CP, later renamed the Mitel MiVoice Office 250. Even the MiVO 250 has been MD'd as of June 30th, 2022. I wasn't a huge fan of the MiVO 250. I tried, I really tried, but the SX-200 ICP was simply better (much simpler to use and program).
