CCaaS is a dead industry. The 'model" of an end to end solution has never been realized and outside of large BPOs has never happened (not to mention a avaya doesn't make profit off of large BPOs). Anyone with a willingness to look at the facts knows this.
As such, Avaya has employed acolytes exclusively for the last decade, & very unfortunately that became obvious to outsiders the moment they created the evangelical communications strategy around 2020.
AM is one smart dude. He knows it's easier to begin a new company by borrowing from an old company. He will use what is left as a springboard to enter a new space and create new solutions. That is the only path forward.
An excellent point by @ufd+1r5zdQhv.
