I have 32 7975G phones on a UC520. I use CCA 2.2(1) for the most part to manage it. I have tried to build some intercom buttons on the 7975G phones. The first few go good. I am able to list and define the destination user and and select a destination button. When i get above 3 or 4 intercoms on any one users phone previously entered buttons begin to disapper from the phone althouh the configuration is stil shown on CCA. I have to return all the button types back to None for all users and then start a fresh. After I enter 4 intercom mappings on any one phone is when the issue arises> The CCA is intelegent enough to not let any two or more users map to the same button of any other user, so this is not the issue.
Is this another one of those areas that CCA is shit and I have to figure out the CLI?
