Sure you can do it, I did it recently. I'm still playing with it because I could not do it the best way possible.
This is a good start :
I also remember a very helpful threat that I found in tek-tips.com about the Avaya side configuration.
Also be aware that the Asterisk IVR side is not too "friendly", it's extremely powerful but if you don't have the right tools it could take a long time to do a simpler IVR.
