IP telephony has been deployed for over 12 years now within Cisco. We are constantly in an ongoing process to refresh our older phones with next generation devices. It’s not easy – it’s a little like painting the Golden Gate Bridge: you’re never finished.
Cisco IT maintains about 21 Cisco Unified Communications Manager (UCM) clusters to support 150,000 hardware phones and 51,000 software phones used by our global employees, contractors and contact center agents. In general, Cisco IT likes to stay up to date, and upgrades to most major releases of the Cisco UCM as soon as possible – frequently this occurs before the code is available to our external customers. We do this to take advantage of new features and to help the product developers identify needed improvements before the release is made available to customers.
Most of us agree “If it ain’t broke, don’t fix it.” Unfortunately, this mindset can cost you dearly when it comes to your network. Like many small businesses, you probably don’t think about the network until something goes horribly wrong. Suddenly you are fighting fires when you could have been strategically planning. (And we all know which of those scenarios is least expensive!)
“An ounce of prevention is worth a pound of cure.”
“A stitch in time saves nine.”
