SIP Trunking: Less Cost, More Services

Voice over IP for business telephony is old news. But when business enterprises like Cisco connected to the outside world, they still used old-world technology. In the past two years Cisco IT has migrated its big connections to the outside world to Session Initiation Protocol (SIP).  This move has saved us millions per year, made our contact center service better, and enabled global collaboration without breaking our budget. It has also simplified our internal voice architecture.

Best of all, it has positioned Cisco to build a B2B voice / video network to enable easier partnerships and better B2B collaboration.

Here’s Rich Gore from Cisco IT, to give a quick and simple overview of SIP, and how Cisco IT is using it to build new services, simplify architectures, and save money.

Zero Touch Deployment in the DNA of Cisco

This video blog describes the value of simplicity in the Internet of Everything world and Zero Touch Deployment (ZTD) as a key enabling technology for Cisco, Cisco IT and any IT organization.

Plamen Nedeltchev, Ph.D. and Distinguished Engineer for Cisco IT describes the challenges and opportunities of zero touch deployment technologies when simplifying the way users and machines consume network services. Plamen shares how ZTD enables productivity through an excellent user experience, allowing fast and seamless consumption of network services while reducing time to capabilities and TCO, simplifying IT deployment and improving scalability.

SDN and Network Programmability: First Five Use Cases for Cisco IT

The Cisco IT network services team views network programmability—the broader category that includes SDN, or Software-Defined Networking—as one of our top priorities.

To clarify terms, SDN is a network architecture that decouples the control plane (that is, the building of a routing table) from the data plane, moving the control plane to a software-based centralized controller. In Cisco IT, we see the real value of SDN as enabling network programmability. Network programmability requires two capabilities: harvesting information from network devices, and automatically pushing out new configurations in response to dynamic network conditions or service-provisioning requests.

We’re in the early stages of weaving network programmability into Cisco IT programs. So far, we’ve identified five internal use cases. Read More »

UC on UCS – The Invisible Servers

Cisco IT completely changed our voice and video infrastructure in the data center – and nobody noticed!

We changed the systems that Cisco IT uses to run ALL our voice and video supporting:

  • 200,000 voice endpoints in 540 buildings around the world,
  • 87,000 voicemail boxes
  • 1600 TelePresence units
  • 8.6 Million Webex meetings per year
  • Our customer contact centers handling 22M calls / year

It was a big job, migrating all these services off of 574 Cisco MCS servers, and onto new Virtual Machines running on 191 Cisco UCS servers in 12 different data centers.  It took a while, but it was truly worth it, despite the fact that nobody noticed.

We reduced the amount of data center resources significantly – less space, less power, fewer cables. Even better, we now have all our voice and video running on virtual machines, making operations jobs and updates and growth a good deal easier, and faster. Best of all, though, we moved all our voice and video to a completely new server platform  — and nobody noticed!

ACE Network: Bringing the Power of Video Meetings to Mobile BYOD Users

I spend a big part of my workday in virtual meetings, as an organizer, participant, or both. When I’m in my office, I can join those meetings from my desktop video endpoint, a Cisco TelePresence EX90, and enjoy the benefits of video communications.

But work isn’t necessarily a place that you go to anymore. I often work outside of my office, so the ability to easily join a video meeting from one of my mobile devices is critical for productive collaboration with colleagues. Read More »
