I was at an MCI/Worldcom seminar a couple of years ago. I had my Avaya shirt on and I sat in the back of the room. MCI was pitching MPLS, and then turned the seminar over to Cisco. Cisco has some great networking products, but that is as far as it goes for me. They don't know voice, and how to manage it. The Cisco engineer start to pick on me in the seminar about how the Avaya platform would handle certain situations, and I answered every one of them. I challenged the Cisco rep to give me 3 references that were using Call Manager in a Call Center environment, with skills based routing, with at least 200 agents. Let me talk to them and see what their experiences are. I have talked to him many times after that, and he has yet to be able to give me any kind of references. It seemed that the audience was very interested in the differences between Avaya and Cisco. I had many people take my business card and call me afterward to ask questions. I have implemented IP in call centers before, but mostly IP trunking between centers. I have a situation right now, where we sold off a part of our company and are moving technical support to another call center. We have had many people go to do training at the new call center, running Call Manager, and they say that our PBX is head and shoulders above the Cisco platform. They could not wait to get out of there, and back to a system that actually worked. They reported many problems, and asked the telecom manager if their system could do certain things (like they had back home) and he said no to every one of them.
I am a true blue (well Red) Avaya fan. Avaya could work out a few things with the customer service, pricing structure, and how they interface with their BP's, but the bottom line is that the system works, all the time. And yes, I worry about job security every day, because stuff just doesn't break on Avaya.
