What is Cisco IT’s UC Global Cluster Architecture?

Over the last 15 years, we’ve progressively centralized our UC architecture. As WAN services have become bigger, better and more cost effective, we’ve been able to rely more heavily on the network to extend UC services out to the branch networks.  Read More »

The Road to Unified Communications – Flexibility, Mobility, Simplicity

When a particularly transformational technology comes along, Cisco IT sets out to be Cisco’s first and best customer. We use it, adopt it, and prove it adds value to the business. By doing this, we’re not only able to show customers the value of our product, but we’re also able to find new-technology issues before a customer might, and give Cisco time to build a better platform.

Cisco IT – Why So Many CUCM Clusters?

Last week, we looked at the question “How close to the phones does the CUCM cluster have to be?” There was no easy or set answer to this question, but we acknowledged right at the start that minimizing the number of clusters is probably a good idea. So why, then, does Cisco IT have so many clusters?

How Close To Your Phones Does a CUCM Cluster Have To Be?

The first things involved in designing a Unified Communications network are deciding where to put the Cisco Unified Communications Manager (CUCM) clusters, and how many clusters to have. And some of the major factors to consider are “Where are the phones? How many are there, and how close to the phones does a cluster have to be?” Read More »

UC and Video – Phones of the Future

What will phones in the future look like?  If our experience at Cisco is any guide, there will be more and more phones, and they will look like almost anything. They will all have two things in common:  they will all bring people together – and they will do it with voice and video.  Always video.

The video may be on a small screen that fits in your pocket, or expands to your pad or laptop, a bigger screen that fits on the desk, or screens that cover the wall bringing people, lifesized, to your meetings from around the world.

At Cisco, we’re using all of these “phones” (although only one or two looks at all like a phone), and they all work together to bring people together, face to face.  Some share more than voice and video, adding presence information and contacts and instant click to call or click to chat or click to share desktops

Here’s Rich Gore from Cisco IT, to give a quick look at these different “phones” in use at Cisco today.
