INE is proud to announce a brand new 62+ hours of the latest v8 CCNP Voice bootcamp. Rerecorded completely from scratch using only UC v8 servers, this in-depth video series covers absolutely everything you need to know for the 5 CCNP Voice exams, with each exam clearly indicated by video title in the playlist. Also, don’t forget about our Bookmark and Note-taking feature in our streaming playlists, as this will help you in your studies.
We’re pleased to announce that our recently announced, highly anticipated CCNP Voice course is available for both streaming and download from our global CDN. Containing everything you need to take and pass the five latest Cisco CCNP Voice exams (642-427 TVOICE v8, 642-437 CVOICE v8, 642-447 CIPT1 v8, 642-457 CIPT2 v8, and 642-467 CAPPS v8), this new course consists of 130 videos totaling over 85 hours of hands down the best CCNP Voice training on the market today. As an All Access Pass subscriber the online streaming version is included at no additional charge. You may also download it now for just $299 or as an All Access Pass subscriber you can download it for only $149.
Each of the 130 videos can be individually downloaded without the need to download the whole class. This will enable you to selectively load them onto any computer or mobile device and watch them at your leisure. Although we do not place any DRM on the files themselves we do limit each purchase to two downloads per video.
Check back often, as we will be adding new labs to our CCIE Voice Volume II Workbook in the upcoming weeks. Also, you may now purchase and schedule your Graded Mock Lab for a proper CCIE Voice assessment of your skills before actually sitting for the actual lab exam.
As everyone knows we’re making a massive push to release more videos and moving over to a new delivery method (HTML5). With this new solution we can support closed captions. I’ve uploaded a sample CCIE Voice Deep Dive video with closed captions enabled to YouTube and wanted to know the community’s feedback as to the value it will add.
Click on the “cc” icon in the YouTube player to enable closed captions if they are disabled.
Closed captions will allow us to offer transcripts of the videos and allow every video to be searchable so you can quickly find which video covers a particular topic and the exact part of a video that it’s cover in. Additionally we’ll be able to link you to that exact part of the video. Let me know what you all think by commenting below.
I am running this week’s Voice Trivia Contest a bit early (launching it on Thursday instead of Friday) to try to give more people a chance to win that might not otherwise see this over the weekend, however we will still end the contest on Monday morning, as usual.
Here are the facts for this week’s Voice Trivia Contest:
- Tobias has a phone on which he needs to be able to have two BLF SD buttons that accurately show the presence status of Gob, Buster and Lindsay’s primary DNs. This needs to include status updates for when either Gob or Lindsay’s primary DN is ringing, but not when Buster’s primary DN rings.
- Gob, Buster and Lindsay’s primary DNs are all in the same Partition.
- Tobias has a SUBSCRIBE Calling Search Space that contains that Partition all three phones’ primary DNs are in.
- Tobias also needs to be able to view Call Lists (Missed Calls, Corporate Directory, etc.), but when he views them, he should only see the BLF status change for Lindsay’s DN, and not for Gob or Buster’s DNs.
- To aid in that, two Presence Groups have been setup. One for Tobias and Lindsay which have been assigned to both their Phone devices and their Lines. One for Gob and Buster, which have been assigned to both their Phone devices and their Lines. The Presence Groups both explicitly have Disallow Subscription to each other’s group reciprocally.
- All is good with Tobias’s BLF SDs on his phone display, and he can see all of their status changes appropriately – including seeing when Gob or Lindsay’s DNs ring, but not Buster’s.
- However, there is an issue. When he pulls up the Corporate Directory and searches for everyone, he sees BLF status updates for both Lindsay and Gob, but not for Buster. Remember that he should not see Gob’s BLF status updates either.
This isn’t exactly the latest news, and doesn’t effect the CCIE Voice Lab exam (although it very well may effect the new CCNP Voice exams), however I am hearing more and more how people are upgrading their Voice routers with newer 15.x IOS code, and not realizing how existing (working) VoIP calls are being broken due to new, intelligent feature default configurations.
Last July, Cisco decided (wisely, IMHO) to create a new style of Toll-Fraud prevention to keep would-be dishonest people from defrauding a company by placing calls through their misconfigured voice gateway(s), at the company’s expense. This new mechanism works by preventing unintended TDM (FXO/CAS/PRI) and VoIP (H.323 & SIP) calls from being able to be placed through a given company’s voice gateway(s), by simply blocking all unknown traffic. Beginning in IOS 15.1(2)T, Cisco added a new application to the default IOS stack of apps that compares all source IP address with an explicitly configured list in the IOS running config, and if the IP address(es) or subnets do not match, all VoIP traffic is denied. Also, the new default for all POTS voice-ports is to not allow secondary dial-tone, making direct-inward-dial the default for CAS/PRI, and PLAR necessary for FXO.
You will find the answer to today’s CVOICE Exam Practice in the comments area of the blog approximately 24 hours after the post. Have fun!
CVOICE-1: Cisco Unified Communications gateways support various VoIP signaling protocols. For each description below, provide the signaling protocol that is described:
A. This protocol specifies the commands and responses to set up and tear down calls. It also details features such as security, proxy, and transport control protocol (TCP or User Datagram Protocol [UDP]) services. It is a text-based protocol that borrows many elements of HTTP, using the same transaction request-and-response model and similar header and response codes.
B. This protocol definition controls VoIP gateways that are connected to external call control devices, referred to as call agents.
C. This standard specifies the components, protocols, and procedures that provide multimedia communication services—real-time audio, video, and data communications—over packet networks, including IP networks. The protocol is part of a family of ITU-T recommendations.
D. This Cisco proprietry protocol is used between Cisco Unified Communications Manager and Cisco Unified IP phones.
Many businesses globally – large and small alike – have been converting calls from routing over traditional PSTN carrier trunks – such as E1 & T1 PRI or CAS – to much lower cost, yet still high performance, SIP ITSP (Internet Telephony Service Provider) trunks for years now. INE is no different than your business with regard to this – we have been using SIP trunks in lieu some traditional PSTN calling for years now as well. In fact, in response to a US Federal Communications Commission sub-commitee’s exploration on “PSTN Evolution” in December 2009, a representative from the US carrier AT&T described the traditional circuit-switched PSTN as “relics of a by-gone era”, and said that “Due to technological advances, changes in consumer preference, and market forces, the question is when, not if, POTS service and the PSTN over which it is provided will become obsolete” – source: Reuters [emphasis mine].
The challenge however, becomes that every SIP ITSP carrier has a slightly different way of implementing these sorts of trunks, and each has different provider network equipment that you, the customer, must connect to, and interoperate (properly) with. If you are a large national or multinational business, you may for instance sometimes even connect to two or three different types of provider network equipment, between possibly having multiple contracts with multiple carriers, and even sometimes having to deal with different provider equipment within a single carrier’s network.
Starting July 1st, we are introducing downloadable content for the CCSP and CCVP bootcamp class-on-demand courses. This exciting new addition will come as a warm welcome to all those looking to have the world’s best training programs on the go. These courses will be offered in .m4v video format and work seamlessly on the iPhone, iPad, and other mobile devices as well as on your desktop.

INE knows Voice. As the only CCIE vendor on the market employing 4 CCIE Voice Instructors, we are constantly trying to pool our collective brain-trust to find a better way to communicate what we know to you, to help you achieve your goals in passing this rigorous practical exam. We’ve all been mulling over for some time now the best possible way to get this information from our heads, to yours. We gave the idea a go where each of us would perform a vulcan mind-meld with the student, however there are still a few roadblocks in the way of us being able to achieve success with this method. The biggest issue we kept running into was that once Petr would step into the room and begin his knowledge transfer, the candidate’s brain would often overheat and we ended up taking a few too many to the hospital to have their brains cooled down with liquid nitrogen. Needless to say – we haven’t quite worked out all of the technical glitches out of our method just yet.
So instead the idea was collectively reached that we should instead develop a brand new product that allows us to perform a sort of “Deep Dive” with each candidate. The concept of this “deep-dive” method goes far beyond what most candidates expect and subsequently receive when purchasing some fashion of Self-Paced On-Demand or Classroom Bootcamp style training. Instead we take one subject, whatever that subject may be for the day, and we vet it fully. To that end I mean that we don’t stop collectively learning until the concept is grasped fully by all candidates.
The format of each class module will be focused around roughly a 4-5 hour window of instruction per topic, however some topics will inevitably go longer. If a topic spans more than the time allotted in a single day’s module, then and there another day to complete the materials will dynamically be scheduled, and any attending students will automatically be added to the continued new module.
The specific breakdown for each module will look like this:
- I will lead the discussion for each and every class module
- We will collectively discuss and fully understand all concepts involved in the technology topic for a given day
- We will then define a very specific set of Tasks to be accomplished
- We will whiteboard the Tasks, notes about them, and how they will be logically implemented*
- We will then demonstrate with live, hands-on interaction, how the concepts are implemented and properly configured
- We will test the configuration thoroughly
- While testing, I will vary the configuration so that we all can see how different permutations effect the outcome
- We will Debug and Trace the working configuration to understand what we ‘should be seeing’
- We will then break the configuration and Troubleshoot with more Debugs and Traces to contrast from the working set
*Each whiteboard sketching will available for download after each module as separate JPG or PDF documents
That is a very true saying – in fact one that we believe strongly in here at INE. However we also understand just how expensive it can be to undertake studying for any CCIE Lab exam. That is why, whenever we can, we try to reduce the load on you – the students – to bear this cost. Take for instance our CCIE RS Volume II for Dynamips – we do all we can to provide you the best available instruction while trying to reduce, or sometimes even be able to eliminate the hardware costs associated with studying.
So now we have taken to task trying to do the same for our CCIE Voice track products. We can’t quite virtualize all of the routers used as voice gateways (pesky DSP’s and TDM trunk cards that dynamips won’t ever be able to support since we actually need hardware for the drivers to be able to trigger the signaling), but we thought we would try to reduce the hardware cost for you, the student, in any way we can with the necessary hardware. Anyone having decided to study for the CCIE Voice lab exam has no doubt realized that even if you decide not to take on the enormous cost of building your own rack to practice with, and instead, to rent rack time from any vendor on the market, you still must purchase your own hardware 7961 IP Phones along with some sort of a hardware VPN solution (such as an ASA 5505 or 851 ISR router) at a minimum in order to be able to practice for all of the most important features tested in the lab. This is quite simply due to the fact that the much older 7960′s and all current SCCP Software Client phones (including Cisco CIPC, IPBlue VT-GO*, etc) don’t support any of the newer features – those that are most critical to studying for the latest lab exam. Even if you can manage to find refurbished 7961 IP Phones from eBay for roughly $150/phone and $500/ASA5505 – you still have to invest over $1,000USD just in hardware before you are ready to rent the rack! Seeing as how the 7961 phones are already a generation behind the current ones, and the possibility that when you pass your lab 6-12 months from now that they will likely be 2 generations old and harder to sell for the same price you paid for them – it becomes a very expensive venture to undertake!
