I put together a new playlist on our All Access Pass geared toward helping those that have decided to study primarily with the new CCIE Collaboration in mind. What will be included in this playlist is primarily new technologies, specifically those that haven’t yet been covered elsewhere in our CCIE Voice v3 products. As the weeks go on, I will continue to update this list with more and more videos covering new technologies in UC v9.1. Keep in mind that until I have this list complete with everything that is newer than UCM 7.x, that you can and should still study all of our CCIE Voice v3 products, as everything except for H.323 RAS/Gatekeeper will still be completely relevant and a very much needed base for your understanding. Once I complete this list, I will probably leave it up for those only wanting to learn the new stuff, like those of you that are already CCIE Voice v3 certified (if you certified on CCIE Voice v2 or v1, and haven’t really used it in a while, you’re going to want to watch all the material over again as quite a LOT changed from v2 to v3). Also, once I complete this playlist with all the new technologies, I will be recording a completely new top-to-bottom CCIE Collaboration Advanced Technologies Class, that will include everything. And of course, the workbook is being completely re-written as well in our new online format, which you can see a sample of here and here. This video playlist is meant to not only hold you over until then, but also to be able to release material to you in a timely, incremental fashion.

To start with, here is 4.5 hours of material on Call Control Discovery over Service Advertisement Framework (CCDoSAF). At a most basic description, this is dynamic routing of DNs over an enhanced, named instance of EIGRP. It is currently much more detailed and complex than ILS (a newer and much more scalable dynamic routing protocol built-in natively to UCM), but it is also currently far more powerful and allows for things like SRST integration for failover usage with PSTN Aliases, as well as cluster-to-cluster PSTN failover, should the primary SIP/H.323 trunk route go down. Cisco pushes ILS much more in production and it is getting much more support with UCM 10.x, but since the new lab tests on 9.x, and the fact that no CCIE Lab exam has ever been that much interested in real-world design –favoring complexity over ease of configuration and good design– and the fact that it is very much on the new blueprint, I’d say you best get used to it now, even if it is going away. Also, I recorded these videos on a UCM v8.5 cluster, but that shouldn’t matter as this feature hasn’t changed since then.

The link for CCDoSAF on the UCM 9.1 Features and Services Guide can be found here.

The link for the playlist is here.

I start off with a general overview including a few slides just for concept, and then I move into hands-on demonstration of the following topic areas:

  • CUCM Inter-Cluster Call Routing
  • CUCM Call Routing with PSTN Failover
  • CUCM Call Routing during SRST Fallback
  • CUCM to CME Call Routing
  • Inter-Cluster RSVP via SIP Preconditions

Enjoy.

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)

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)
