I reckon this is just an action item following Chapter 11—cleaning up the backyard, so to speak—before remodeling the support model.
There’s a lot of firepower and experience in the team to be simply trimmed off like that, so I believe they’re dismantling things just to clear out the cobwebs before regrouping. I sure hope my sense of optimism holds true; otherwise, it’s going to be a tough road ahead for Mitel in that region when it comes to support.
