25 Hours of Training
Take your CCNA certification to the next level by getting certified in the still greatly in demand area of Voice over IP.
This course focuses on real-world demonstrations to prepare for the CCNA Voice track or the new CCNA Collaboration track.
We don't just browse over topics in our training, but provide detailed explanations and lots of hands on demonstrations.
Please read the course reviews to see what customers thought about the course:
"This is the most comprehensive CCNA Voice course on the market"
"I have tried most of them: CBT Nuggets, IPexpert, Trainsignal and (and in my opinion) one of the worst on the market -> INE but David's CCNA Voice is wonderful. It is very structured; to the point; with filled with a lot more Voice fundamentals than you need for the exam but very useful for the real-life experience. Thank you Dave for such comprehensive course."
The main products the course covers are:
· Cisco Unified Communications Manager (CUCM)
· Cisco Unified Communications Manager Express (CUCME)
· Cisco Unity Connection (CUC)
· Cisco Unified Presence (CUP)
We go into much more detail than the Cisco Certification exam with many real world examples and demonstrations.
The course consists of over 33 videos and over 23 hours of video training. You can DOWNLOAD the videos.
We have also added some bonus material to help you understand complicated voice topics.
OUR FOCUS: Practical, hands-on demonstrations using the equipment. We don't just talk about a topic. We demonstrate it using multiple phones communicating with CUCM or CUME or Unity Connection etc. Watch the calls be set up, transferred, torn down and so forth in real time.
I have taught this course live and the biggest issues are:
1) Limited time.
2) A great deal of content
This video course allows me to explain and demonstrate concepts in far greater detail than would be possible in a 5 day course. There isn't enough time to explain all the concepts properly in a standard instructor lead course. However, here I am able to do that. I have even added some additional content from the CVOICE course to explain and demonstrate more advanced concepts.
Why pay $4K+ for an instructor led course (with some companies) when you can get all the content here for $49 ($19 with current Back to School Campaign)?
And watch as many times as you like, watch on your iPad and even download all the videos!
"Very engaging. He covered all and then some. Best one I have taken. Well worth it!!!"
- Dave Keys
"David offers practical easy to understand topics of the CCNA Voice 640-461 exam. He has in depth knowledge of theoretical concepts as well as hands on experience. I will recommend this course to anyone who's just starting out in Cisco Voice."
