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.

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!
