Pros
If you are a geek and love unfinished and moreover untested products, this is the place for you. If you are a real bullshit-artist and can build a career while foregoing a reputation of trustworthiness, then you are likely to get results at Avaya. If you like reinventing the wheel every day you come to work, come over and move some paper @Avaya.
Cons
This is a company that doesn't even use its own products. Voice-messaging wasn't use by management to communicate sharp, immediate and confidential information to the company's employees in a timely fashion across the globe. Instead, they rely on regional VP's communicating to their "teams", but at their own wim and totally unsupervised. Individual or team contribution to long-term revenue-streams is neither recognized nor compensated. Avaya is a headless company, without a customer-strategy and no long-term industrial product vision. Ttoo many back-slapping chiefs at Avaya, who don't understand the value of the very skilled professionals who eventually will get hired away to Cisco and other great techonlogy companies.
