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:
I really do not why I don’t care much for Voice Over IP. It’s certainly technical. Heck man, if you’re stuck on QoS, go ask a voice geek. Resellers are begging for more voice engineers, so it’s a great career path. You can really do some very cool things with it that your end users just will love you for. Heck, if there’s a more visible direct impact to a business other than voice, I’d like to know what it is.
But still; when funding comes thru for a voice show I’m always thinking…”meh”… Which is funny because without a doubt our best and most award winning shows have been on voice! You’d think I’d love it right? Hey ya what? when was younger growing up in the hills of Tennessee (hereby referred to as God’s One True Love from henceforth) my first experience with hacking was on our telephone system with rapid hook switch tapping to become a tandem or punching thru busy signals was a real hoot. Of course the Capt’n introduced us to blue boxing and a splendid time was guaranteed for all…
Next week is a TechWiseTV taping week for us. Right now, this show has two things going against it; first off, it’s a voice show and second (and most important) it’s also an upgrade show. Yep folks, that’s right a push to get you to upgrade your CUCM.
Now look, we all have bills to pay so there always some level of butt kissing and boot licking that has to go on any show. Video is expensive. For me, I never ever ever promote ANYTHING on TechWiseTV that I would not be happy to stand by or even support in the future. I’m grateful TechWiseTV can do that. We turn down shows because we just do not believe it’s the best for the network. Like my Grandmother taught me all those years ago…”If ya ain’t got nuthin’ nice to say, then shut the friggen crap up goober…” Ah she was quite the wordsmith for sure.
I don’t know about y’all, but I am not a big upgrade person at all. Upgrading sucks worst then a going camping with your mother in law on Indy 500 race weekend and forgetting the beer. From and engineering view point; why fix something that isn’t broke? Upgrading means my hardware is going to be slower (if it’s compatible), my licensing is going to be really messed up, tech support is going to be worthless, major downtime, oh yeah…and this is voice? Namely Cisco voice, wholly friggen shnikasourus rex man! You need a PhD in CUCM licensing to figure that one out, plus my dial plan, migrating my DB…and you know what…that camping trip is looking better all the time now….
Robb and I designed this show to have the voice team prove us that we need to upgrade. To be honest, they better bring their “A” game. ‘Cause I ain’t buying it yet. TechWiseTV is unscripted and we do not see the content that our guests bring on the show beforehand. We like to keep it real and spontaneous. We just ask that slides have minimal words, no marketing or vision statement crap, any quote from any analysis puts you in Aldrich Ames status and removed from the set and have the slides in 16×9 format.
I’m bringing all of these doubts onto the set on Tuesday morning to see if they can address them. It’s still early, so if there is something you want to make sure we cover, toss in your comments before 16Jul13 and we’ll cover ‘um…then tune it see…upgrade or not?? In the meantime, anyone got a tent I can borrow?

A pound of feathers weighs more than a pound of gold. This is because feathers are measured in avoirdupois weight which is 16 ounces per pound and gold is weighed in troy weight which is 12 ounces per pound.
