Cav,
from what I understand, iWD is the only thing you will be able to use to handle your multi-channel routing, so, there is little to do but just go with it.
I have severe reservations about the current layout of IWD
• iWD Manager— I keep on wondering why they could not integrate this functionality into any of their other Administration GUIs. Building it on top of Java not only makes it ugly (my personal opinion), but does not feel as part of overall Windows experience. Did I mention that Java version mismatch and privileges settings are the main cause why I gave up on using Java apps on Windows?
• iWD Runtime Node—A standalone Java application - why is stand-alone? Seriously, there is pleothora of existing native services for Windows and Linux to use instead!
• Genesys Rules System—Rules Engine and Rules Authoring Tool are web applications that run on ISS with poor Tomcat support (at least IMHO). The Rule Development Tool is an Eclipse plug-in, meaning you develop in Java editor and run it on IIS? Really? And why can't this be an integrated part of Exchange system??? And why is it not taking into account Active Directory??? Why Rules engine cannot be URS?
Reporting ....yes, they are still using ETL, which retrieves the data from interactions server. Sounds familiar? Well, thats because it is ICS all over again.

And of course, the infamous DataMart. and if you want to get it to work with your STAT SERVER, you need....a Java extension. JAVA. For Stat Server. Unless STAT SERVER can run using Catalina, I do not see a reason for mixing a pure C++ application with Java plugin.
I see what Genesys is doing, but I do not think that the architecture is there, the platform is well thoought out, and lack of Active Directory support makes the whole process of setting roles and tasks redundant.
I think Genesys has a potential for a great product, but it must:
- tie with Active Directory
- provide easy integration with Office365 and Lync
- streamline the data collection process and stop using ETLs
- build library for Stat Server that allows for tighter integration with iWD DM
Well, that's what I think. Other than this, if done properly, it will be a great product I would love to place at customer site.
