Migration – How did Cisco IT get from Legacy PBX to Unified Communications?

There is plenty of reading collateral out on the internet that covers the “technology” side of migrating from a legacy voice system to IP Telephony and Unified Communications (e.g. Cisco Collaboration Systems Migration and the Cisco IT Migration Best Practice) but not much that covers the human aspects that need consideration.

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.

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.

Deploying Extension Mobility Globally

Cisco employees are moving towards a mobile collaborative office environment – within the workplace. We sit where we like and log into the nearest phone, using extension mobility. But when we traveled to different Cisco offices around the world, we couldn’t log in to the Cisco IP phone:  extension mobility only worked at certain limited locations within our home region.

Now, employee phones can essentially follow them to any Cisco office worldwide because Cisco IT deployed the Extension Mobility Cross Cluster (EMCC) feature on Cisco Unified Communications Manager (Cisco UCM).

Migrating a Large Cisco UCM Cluster to Cisco UCS over the Weekend

To serve our headquarters campus in San Jose, California, Cisco IT deployed one of the world’s largest Cisco Unified Communications Manager (Cisco UCM) clusters, with 9 pairs of subscribers and a publisher supporting this one campus. Together with these main 19-servers the campus cluster also includes Unity node servers, presence servers and management servers, for a total of 48 Cisco MCS 7845s. In June 2012, we migrated these legacy servers to virtualized machines running on Cisco Unified Computing System (UCS) servers over a single weekend. Read More »
