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
