This post questions the plan by Cisco to cease offering support for UC540/560 systems configured outside of CCA.
I have recently installed a new UC560 for a client and I must stress knowing that Cisco was going top cease offering support I made sure I used CCA entirely even though I love using the CLI on anything I can get my hands on. After using CCA for everything the following inexplicable problems occur:
1. After installing the system and testing all features at the client site one evening I returned to the site the next day to find that no-one could dial out. Nothing in CCA stood out as being the problem. I lodged a job with TAC and the excellent tech and I went through the config and after an hour we both discovered at the CLI level that all of the dial-peers were shutdown. This doesn't appear to be possible from CCA so how it happened and how I was supposed to see the problem I don't know. The only way to fix the problem was via the command line.
2. I made a change again via CCA to add a shared line to every extension and it worked fine and achieved what I wanted it to. Yesterday I received a call from my client that something wasn't right and when I looked at the shared lines I added it is now showing as Normal on every extension, not shared. I couldn't have added the line as Normal via CCA as it doesn't let you so how it changed from Shared to Normal I don't know. Again the only way for me to fix this is via the command line.
3. On another system using the same version of CCA I updated a persons name on the system in Configure - Telephony - Voice - User Extensions. When I applied the change all of the local Australian dialpeers were replaced with US ones. I didn't go into the Dial Plan - Outgoing area at all so why CCA decided it wise to replace these I don't know.
There is an interesting thread from July here Re: ASK THE EXPERTS - UC 500 SYSTEM VOICE TECHNOLOGIES which questions the move as well, with the response that future versions of CCA will ensure more reliability. I wonder whether things have improved in the last three months.
I must stress that the Small Business Pro product range is fantastic and one which I really enjoy selling and supporting but with product margins being as low as they are I can't afford to spend the time fixing issues that should not happen.
