Last week we quietly snuck into the All Access Pass the recordings of the live UC on UCS and Nexus 1000v on UCS classes that I ran just a few weeks back. If you have never run Unified Communications in a virtual environment or have never worked with a distributed virtual switch in a VMware environment, these classes will certainly aid you in preparing for that first deployment. If you have worked with either product for a little while, these classes will deepen your understanding of what’s needed and what’s really going on behind the scenes. The Nexus 1000v class is also very useful for the Unified Communications engineer, as most deployments these days are virtual machines, and the Nexus 1000v is the recommended L2 switch to run them on, since the UCS can only match/mark at L2 CoS, whereas the Nexus 1000v allows you to match the L3 DSCP that the UC servers are natively sending and map them to a L2 CoS value, which is currently the only value seen and honored by any of your UCS or Nexus switches in your modern data centers.

I will be furthering this series with classes on the VSG with VNMC, the ASA 1000v, and later with the InterCloud 1000v as well as possibly more virtual devices in the weeks to come.

A number of people had indicated that they thought my CCNA-to-CCIE-in-a-Year program was a bit aggressive for those with both family and job life to consider, so I’ve revised the plan into an 18-month plan, and also added a downloadable XLS spreadsheet to assist you in your studies. Simply plug in your starting date, and the spreadsheet should keep you on task on a week-by-week basis. Here’s the link to my previous blog post where you’ll find the updated plan to download, as well as links to all of the products used in the plan: From CCNA Voice to CCIE Voice in One Year – A Detailed Study Plan – REVISED Dec 31, 2012

Since it looks from here at Cisco Live like we won’t be updating any CCIE Voice topics anytime soon (looks like roughly 12 months out – so rest easy and keep studying), then this post is most likely one that CCNP’s will be focusing on for now – though CCIE’s will still certainly benefit from this as well.

Here we will continue our series on Call Control Discovery via Service Advertisement Framework. Today we’ll look at the 4th video in that series (video #56) from our current 62-hour CCNP Voice v8 bootcamp.

  • CCD via SAF :: Overview (29m)
  • CCD via SAF :: CUCM Inter-Cluster Call Routing (1h 32m)
  • CCD via SAF :: CUCM Call Routing with PSTN Failover (29m)
  • CCD via SAF :: CUCM Call Routing during SRST Fallback (48m)
  • CCD via SAF :: CUCM to CME Call Routing (54m)
  • CCD via SAF :: Inter-Cluster RSVP via SIP Preconditions (21m)

Once we finish this series (probably in the next week), I will be starting a brand new long-running series around all of Cisco Unified Contact Center Express and advanced scripting. We’ll start with the basics for every one to be able to follow along, but very quickly ramp up to the advanced scripting sessions, so stay tuned for that. It’s something a lot of students I’ve run into here at Cisco Live asked for – and we love to listen to what you all want.

By the way, should the lab be updated anytime sooner – you can already see from this post that INE is way ahead of the development curve for advanced UCM topics, including UCM v9 and TelePresence topics. We’ve got you covered with the normal extremely in-depth knowledge that you need – not just to “pass a lab”, but rather to truly make you an Expert!

The rumors have been swirling for many months now about a (seemingly) overdue update to the CCIE Voice blueprint, and having wondered about them myself, I decided to contact 3 proctors that I know and speak with regularly. While they (of course) could not divulge anything specific, they had all heard ‘rumors’ themselves. No one knows exactly when we might see an update officially announced, but two main theories seem to exist as to when it will come.

  1. It will happen one week from today at Cisco Live during the paid 8-hour CCIE Voice seminar

  2. OR

  3. It will come sometime during the month of July

The reasons behind the two schools of thought is that the first just seems to make sense 1) Big Cisco event, seems like the perfect time to announce, and 2) Wait until UC v9 comes out of beta to give a bit more longevity to the exam (have the version of UC servers being tested not as ‘old’ 3 years from now when they update again). It’s possible Cisco could even surprise us and announce a new lab blueprint at Cisco Live and announce the still-in-beta v9 – though I personally think that is much less likely to happen.

Either way, INE will be there to update you live. I will be tweeting and live blogging from the 8-hour CCIE Voice seminar one week from today (Sunday, June 10) beginning at 8am PDT (GMT -7). I will also be tweeting anything interesting that we might find out about the CCIE DC track during the Monday morning session.

At a minimum, we will see an update to UC v8.6 servers, at the maximum, v9. While there are a number of new enhancements to v9 such as redacted and redacted (after all it is still in beta and NDA ;-) ), I personally don’t think it will make too much of a difference either way.

Some of the things we know almost certainly that we’ll see updated are new UCM technologies such as:

  • UCM Session Management Edition (SME) – Think of UCM as a hierarchical proxy/gatekeeper over multiple UCM clusters (my guess is one cluster would be pre-configured)
  • Call Control Discovery (CCD) via the Service Advertisement Framework (SAF) – think IGP dynamic routing protocols for DNs
  • Extension Mobility Cross-Cluster (EMCC or some say CCEM) – nuf said
  • SIP Normalization via Lua scripting language – this is cool
  • Geo-Location Filtering – basically restricting VoIP-to-PSTN hop-off in certain areas due to government law
  • LDAP Custom Filters – self explanatory
  • Security! – This is clutch these days, and UCM 8 and above have it in spades (and an absolute necessity for things like EMCC)

Now, some of the things that I’d be willing to wager on, but we certainly can’t be sure of until announced are things such as :

  • TelePresence Video Communication Server (VCS) (and possibly even VCS Expressway with an ASA)
  • ISR-G2 voice/video gateways with PVDM3 – needed to conference/transcode/transrate/transsize Video
  • 89xx or 99xx series phones – I’d pick the former since they have newer models with built-in cameras – go figure
  • Jabber Client (replacing CUPC)

One that I don’t think can be tested is the Intercompany Media Engine (IME). This in a nutshell is the ability for UCM clusters to securely ‘discover’ other UCM clusters out on the internet (between multiple companies or autonomous organizations) and learn/build secure SIP trunks between them and then auto-route calls between them. This contrasts with Call Control Discovery (CCD) which is used to auto-learn DNs from other UCM clusters, but within a single autonomous organization. CCD only requires 2 UCM clusters with 2 routers to provide the EIGRP-driven Service Advertisement Framework. IME requires 2 UCM clusters, 2 IME servers each with reachability to either GoDaddy or Cisco.com, and 2 ASA’s to build the secure linkage between them. It is for this reason that I highly doubt that IME could/would be tested.

Whatever may be announced – one thing you do not need to do is panic. Yes, these are new things that you would have to learn. Yes that may take some time. However everything you have already been studying is still 100% relevant and necessary to know. Not only that, but you’ll have around 6 months to finish up your studies and pass the exam before this new blueprint would go into effect.

Also, and perhaps much more importantly, INE has you covered. I’ve already been teaching all of these new topics for well over a year now in certain settings. Most of them can be found in my recently released 62 hour CCNP Voice bootcamp. I’ve also recently started a blog series on Call Control Discovery (CCD via SAF). It has 5.5 hours of video teaching you everything you need to know. Also I will begin another blog series on Extension Mobility Cross Cluster (EMCC) directly following the week of Cisco Live.

Follow me and stay updated throughout the conference!

It’s sure to be a great time at Cisco Live even if we don’t see an update. Hope to see you there!

So we continue our series on CCD, something that is being talked about lately – in conjunction with UCM SME (Session Management Edition – think UCM as a Gatekeeper for other UCM clusters) – and something that is bound to be covered on the next version of the CCIE Voice blueprint (something that’s received a lot of chatter lately with the advent of UCM v9 beta training this week). Also, a topic that you must know understand well today if you are studying for your CCNP Voice CIPT2 exam.

Today we’ll look at the 2nd video in that series (video #54) from our current 62-hour CCNP Voice v8 bootcamp.

  • CCD via SAF :: Overview (29m)
  • CCD via SAF :: CUCM Inter-Cluster Call Routing (1h 32m)
  • CCD via SAF :: CUCM Call Routing with PSTN Failover (29m)
  • CCD via SAF :: CUCM Call Routing during SRST Fallback (48m)
  • CCD via SAF :: CUCM to CME Call Routing (54m)

Cisco keeps giving this week by allowing any desktop to join – for free – into any existing Telepresence video, and the quality of this video is really, really good. John Chambers recently said that Video is already the #1 traffic driver over Cisco’s internal network, and that by 2013 it is expected that over 90% of all traffic over the internet will be based on Video. There’s never been a better time to be training for Unified Communications!

I will shortly be resuming the series I began on troubleshooting, but in the interim I have been getting a lot of emails from people regarding one of the newest sections of the CCNP Voice certifications (specifically it falls under the CIPT2 642-457 exam) dealing with Call Control Discovery (CCD) running over Cisco’s new Service Advertisement Framework (SAF) – a really cool new protocol with lots of potential. So I thought I would make public a new 6-part series that will cover every aspect of CCD over SAF.

This is something that I am sure CCIE Voice students will be interested in as well, because while we don’t know exactly when the change in blueprint is coming to our beloved lab, we all know it’s coming. Most of you I understand from your emails fear its arrival – even though there is nothing to be afraid of. In fact, this is one of the biggest changes in UCM in v8. And it’s a good idea to learn it now, since there are far more changes coming in UCM v9 and you know that will be on the lab as well (there are way too many to go into and they’re still under NDA, but once I can I’ll begin outlining them). Might as well get the biggest change for UCM 8 out of the way now!

Here are the topics we will cover via video and in this order:

  • CCD via SAF :: Overview (29m)
  • CCD via SAF :: CUCM Inter-Cluster Call Routing (1h 32m)
  • CCD via SAF :: CUCM Call Routing with PSTN Failover (29m)
  • CCD via SAF :: CUCM Call Routing during SRST Fallback (48m)
  • CCD via SAF :: CUCM to CME Call Routing (54m)
  • CCD via SAF :: Inter-Cluster RSVP via SIP Preconditions (21m)
