If you recall from a past article I wrote about "Which Phone Should I Use?” – A Comparison of Models, you may remember from the graphic that support for remotely controlling SIP & SCCP IP phones in CME or SRST was coming approximately around Feb 14. Well, I now have a new graphic to replace that old one (after the jump):

That's right, the very talented and kind folks at Variphy, have just updated their Variphy Insight Remote Phone Control software to include support for SIP and SCCP phones connected to both CME and SRST (either traditional SRST or CME-as-SRST). So now there are literally no phones in our racks that cannot be controlled via our web-based remote phone control client!

Watch the new instructional video here!

Also, I am including just below, the small bit of additional configuration needed to make the Variphy Insight software work with CME for both SIP & SCCP phones. Please note that there is no additional configuration needed to make Variphy Insight work in controlling phones that have fallen back into traditional SRST or CME-as-SRST, due to the fact that they keep their Authentication URL string during fallback, and continue to authenticate via the CUCM (I speak to how exactly this works with INE's racks in the instructional video). Please also note from the below that there is no need for any "ixi" configuration, and I only threw it in below (in shutdown state), to reinforce that principal. In fact, this is what makes it possible to control SIP phones in SRST and CME, since the IXI subsystem currently only supports control over the SCCP CME server and its endpoints.

voice register global
url authentication
username variphy privilege 15 password cisco
ip http server
ip http authentication local
ip http path flash:gui
ixi transport http
ixi application cme
url authentication variphy cisco

We are in the process of updating all the voice racks in our data center to include this latest version of the client, so be patient as it may take a couple of days to get every rack updated with the new software.

Also stay tuned for some exciting news coming up in the very near future regarding the ability to use all of our Voice rack functionality with NO VPN connection!

Happy Labbing!



Mark, I'd just like to say thanks again for the course. It was invaluable and played a huge part in my passing. I passed on my third go, last month just after the course. Without the tips and advice you provided in the bootcamp, I have no doubt I'd still be trying.

- Kevin Lloyd, CCIE Voice #27994

Congratulations Kevin!!


Lab's 1 & 2 from INE's current CCIE Voice Volume II Workbook have been completely re-written from the ground-up, and have now been pushed to all subscribers in their INE Members area.

These two new labs both contain video-based solutions, which walk you -- task-by-task -- through every step of the necessary configuration, along with plenty of live troubleshooting, just as we should expect when sitting for the actual CCIE Voice Lab exam.

For the first two labs alone, we have recorded over forty hours of video-based solutions.

We are in the process completely of re-writing every lab in the Voice Volume II Workbook, and will be releasing them and posting announcements here about each new lab as they are completed. We will also be releasing new CCIE Voice Deep Dives here shortly. So stay tuned for much, much more from INE's Voice program.

Happy Labbing!



In our series on CCIE Voice Troubleshooting and issues you may encounter during your lab exam, we last looked at problems with European MGCP GWs and Mobile Connect, and today we would like to continue that series by exploring the issues that you might run into in a number of situations related to logins to the Cisco Unified Contact Center Express product.

Perhaps one day you go to login to the UCCX Administration page, and you find that the user that either you, or someone else setup -initially in CUCM and told UCCX to use as it's administrative login- no longer works properly. You try and reset the password in CUCM (or possibly in Active Directory), and then try to login to the UCCX Administration page again, but alas, still no luck to be had. This issue could present itself in a number of situations, perhaps in self-study, during the actual lab exam, or very possibly even in a real-life scenario.

This video from our brand new Volume II lab video solutions will walk you through both the problem and quick solution to get you back into your UCCX, and able to re-link either the existing/should-work administrative user, or choose a new user for all future admin logins.

Happy Labbing,



The Cisco Unified Communications feature called Mobile Connect (also familiarly referred to as Single Number Reach) is truly a great feature of Unified Communications Manager, and can provide us with many efficiencies both in being able to be reachable just about anywhere, and in being able to be easily identified when placing inbound calls from our mobile phones into the CUCM cluster to our colleagues. As admins, we know that if we wish to have our users place calls from their mobile phones inbound to their colleagues inside the CUCM cluster, that we need to match up all or at least part of their inbound calling party number (CLID) to their CUCM Remote Destination. But what happens when what the carrier is sending CLID digits inbound to our IOS voice gateways that differs significantly from our Remote Destinations in CUCM, especially if we have truly embraced Cisco's push toward true Globalization in v7.0, v8.0 & v8.5?

The fact is that many, if not most European carriers (as well as many more all over the world) send CLID in through an ISDN PRI into the enterprise gateway with a preceding "0" as a courtesy  digit for easy recognition and ease in dialing back out, since this "0" is very commonly used as a carrier-recognized national dialing prefix. If we were speaking of the US and Canada, this "0" we are speaking of would be akin to dialing a "1" prior to the national number. Now in the US and Canada, if a carrier in the US sent CLID into a gateway with a "1" preceding any 10 digit number, this would work fine since the US/Canada country code also happens to be "1". However, the "0" preceding a variable length number is not valid in a true E.164 number format (e.g. If you dialed the phone number from outside of whatever country we were talking about, you would omit that preceding 0 from your dialed digits).

So what are we to do to get our inbound CLID to match our RD's?

That is exactly what we will explore here today in video format, as you watch a very small excerpt from our video-based solutions to one of the many new labs we will have in our new CCIE Voice Volume I & II workbooks.

Happy Labbing,



I have been asked for many years now, "What is the best phone to use when studying for the CCIE Voice exam?". And while this answer has changed over the years with the different blueprint requirements (with no doubt whatsoever it will change again come next blueprint), the answer for the past year and a half has been a tough one. You see, the actual CCIE Voice lab exam uses Cisco 7965G phones - which you certainly do not need to run out and buy, since all of the same features can be tested using a lesser model, say a 7961 or 2 hardware phone (only difference would be the background image - color and resolution). And certainly, without a doubt, using hardware phones --attached to an INE / GradedLabs Voice Rack using hardware EzVPN through a Cisco IOS router or Cisco ASA-- is hands down, the absolute best way to study.

However, not everyone has the capital outlay needed to achieve such a pristine study environment. In fact, when we at INE got together with another company to offer a discounted rate to students on some 'remote phone control' software --so that students could get the 'next best thing', namely controlling the same hardware phones without purchasing them-- the price still exceeded many of our clients' budgets. They would say (a bit incredulously) to us, "You mean I spent all this money on your great self-paced products, but  now I get surprised to find that I must spend more money just to make your racks work for my lab session??". And you know what? I tend to agree with them. It didn't seem all that fair at all. And then that company decided to raise their prices, which I understand -business is business- it just didn't fit with our needs for our students any longer. So now, after having been approached by every company in this comparison list to use their product, we settled with what we believe is far-and-away the absolute best among them, Variphy Insight, and let our clients use it for free. That's right, it costs you absolutely nothing to use our remote phone control software with our racks. And we have FIVE 7961 phones and one PSTN phone attached to every single CCIE Voice rack.  Not only is their product lightweight by the pure use HTML, but it can be used with any OS.

So what I have done is, after carefully evaluating many possible methods of hard-phone vs. softphone vs. remote phone control software, put together a side-by-side comparison of many of the more popular means of studying for the CCIE Voice exam. This list is by no means exhaustive, however it is a very fair look at each product and what it can offer you in terms of 1) Cost, 2) Features, 3) OS Support, and 4) Ability to Use One Client for everything you need to do in your CCIE Voice self-paced studies. I hope this helps some people, and please comment on things you like, dislike, or would like to see, and we will do our absolute best to accommodate you.

Voice Self-Study Phone Comparison

By the way, we will be releasing complete rewrites with exhaustive video solutions to our Volume I and II workbooks in coming weeks - a few will release in less than 2 weeks.

Oh, and stay tuned for some upcoming announcements soon that will make your self-studying even easier!

Happy Labbing,

INE is happy to announce that we now have all 21 Modules of our new CCIE Voice Deep Dive completed --115 hours of recorded class-on-demand style video (no breaks or dead-air in the recordings - that's 115 hours of actual learning!)-- completed and ready for your consumption!

As we mentioned in a previous post, The author and poet Maya Angelou said “Words mean more than what is set down on paper. It takes the human voice to infuse them with deeper meaning.”. Well that is certainly what we have attempted to do with the CCIE Voice Deep Dive self-paced Class on Demand series – that is to bring the human instructional voice element to infuse deeper meaning to what is already fantastic Cisco Documentation. Anyone that has set out and determined to undertake the task of studying for and ultimately passing any CCIE Lab exam, knows that at some point during your studies, the words on paper (Cisco Docs, RFCs, books) – while a absolute phenomenal source of information – can at times seem to loose their impact. Perhaps you have been studying too long, read one too many docs, have the time pressure of your family and friends waiting for you to return to be a part of their life, or perhaps you are just starting out on your adventure and don’t know where to begin. Whatever stage you are at or whatever the case may be, it is certainly helpful to have a tutor and mentor there beside you at times, assisting you in understanding what each complex technology’s documentation is trying to teach you, in possibly a deeper and more insightful way than you can manage on your own.

For each complex topic we have held (or will soon hold) an online class where we dive down deep and explore all the concepts, practical application, and troubleshooting associated with each technology topic. The general format for each Class-on-Demand Deep Dive module spends between 4-7 hours on the given topic for that day, and during that time follows this outlined training methodology:

  • Collectively discuss and teach all concepts involved in the technology
  • Whiteboard concepts to further deepen every participant’s understanding
  • Define a specific set of tasks to be accomplished
  • Demonstrate how the tasks and concepts are implemented and properly configured
  • Test the configuration thoroughly
  • Vary the configuration to understand how different permutations effect the outcome
  • Debug and trace the working configuration to understand what should be seen
  • Break the configuration and troubleshoot with debugs and traces to contrast from the working set
