I agree - if the original project plan didn't include an upgrade at some point - 10 years is probably good - then they suck. I imagine even if there was a plan, it probably was poopoo'd as not necessary because the old mechanical switch lasted 60 years, why won't this fancy new electronic one that's running on a couple of IDE 1GB hard drives? I just tossed a complete Avaya PBX system, and a Merlin 820D2. Both were EOL, but the Avaya VOIP PBX was barely 10 - the Merlin was well over 40 and was given to a hobbyist who wanted to bring it up in his house. The Avaya was dying due to the aforementioned hard drive failure and the fact that the OS was on a CF card. Whomever thought that was a good idea should be shot. The Merlin was acting up but it was still going fuck you, I'm routing calls until the world ends.
