How does Cisco keep voice costs down with our Unified Communications voice service? Read More »
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?
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 »
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.

Welcome back! We take things to the street in this episode of Engineers Unplugged. Ronald Beck (@tallnetninja) and Mark Gonsalves (Cisco) discuss real world two-way communications when there are radio interoperability challenges. Enter IPICS server and the policy engine. Because you really want comms in the field to work. This is a great episode full of real-world examples, let’s watch:
Welcome to Engineers Unplugged, where technologists talk to each other the way they know best, with a whiteboard. The rules are simple:
