I believe this is Avaya's 2nd chapter 11, previously before that when it was Lucent it also went into bankruptcy or almost I am not sure which... I am not sure it AT&T ever filed for Chapter 11 though..
I have never understood why investors continue to invest in this company. I say that even though I actually use /administer an Avaya on a daily basis, I like their product, we use it mainly for the call center but also for internal calls, the call routing is simple, efficient and easy to put together complex IVRs and routing scenarios..
It's just a shame that it appears to be managed by scam artists and corrupt businessmen..
