Thanks for the response. I've done networking and set up IP sets on other systems, that stuff seems pretty straight forward. I have the Adtran ATSA Cert. I hope that counts.

When I took the IPEdge test I do remember the Adtran ATSA was an accepted cert.
For me it seems like the basic difference between the older DK and Nortel systems and the CIX is the way the CIX processes an incoming line calls. With the other systems you program extensions to ring and then the voicemail(or voiemail hunt group) to answer on a delay. With the CIX it seems like a push system, where you send the call an extension or multiple call group, and then the call forwards to voicemail.
In the CIX I like to use a multiple call group to handle the call. There I would have a table of all the phones that are supposed to ring, and then I can send the call to voicemail, and even designate a specific voicemail box to answer. There are a few minor quirks with MCG, but this is how I program most systems.
