 SIP (Session Initiation Protocol) Fundamentals Video

Session Initiation Protocol (SIP) is seemingly everywhere these days; voice, video, instant messaging, telephony providers all rely on SIP to establish, maintain, and tear down media sessions. SIP is supported by nearly every vendor and used extensively in today’s IP collaboration networks.

In this video Sunset Learning Institute instructor John Meersma gives an introduction of what SIP is and how it works. In addition, John uses tools such as call trace and debug to examine and explain SIP messages.

 Cisco IOS Voice Translations – Part 1: The Basics of Voice Translation Rules 

Many of my students find that reading (let alone writing) voice translation rules and profiles in Cisco IOS very confusing. And with good reason – the regular expressions used to build the rules themselves take some getting used to. Add to that the application of a set of those rules to a port, dial-peer, etc. – in a direction of a call’s flow, both inbound and outbound – for called number, calling party and redirect numbers – and that you can use rule sets to manipulate each of those numbers multiple times for a single call, and the whole voice translation process can become overwhelming. (Aspirin anyone?)

This is the first of a series of articles on Cisco IOS Voice Translations. In this part, I’ll cover how to read and write simple regular expressions to construct individual translation rules. Future posts will cover how rule sets and voice translation profiles are built and applied, advanced regular expressions and special applications of voice translation rules, and tools you can use to test what you have built.

 Cisco IOS Voice Translations – Part 2: Writing and Applying Voice Translation Rules and Voice Translation Profiles 

This is the second part of a series of four articles on Cisco IOS Voice Translations. In Part 1, I covered how to read and write simple regular expressions to construct individual translation rules. This article will cover how those rules are combined to create and apply rulesets and voice translation profiles. Parts 3 and 4 will discuss advanced regular expressions and special applications of voice translation rules, and tools you can use to test what you have built.

 Cisco IOS Voice Translations – Part 3: Building and Applying Advanced Expressions in Voice Translation Profiles 

This is the third part of a series of four articles on Cisco IOS Voice Translations. In the first part, I covered how to read and write simple regular expressions to construct individual translation rules. The second part covered how rule sets and voice translation profiles are built and applied. This post will discuss advanced regular expressions and special applications of voice translation rules. In the final post in this series, we will look at the tools available to test and troubleshoot voice translations.

 Cisco IOS Voice Translations – Part 4: Testing and Troubleshooting Voice Translation Profiles 

This is the fourth part of a series of four articles on Cisco IOS Voice Translations. In Part 1, I covered how to read and write simple regular expressions to construct individual translation rules. In Part 2, I covered how to combine rules into rulesets (voice translation-rules) and the rulesets into voice translation-profiles. Parts 3 took this one step farther and discussed advanced regular expressions and special applications of voice translation rules.

Now that you have the tools to build voice translation-profiles, in this article we will look at the tools you can use to test what you have built.

 John Meersma’s Cisco Voice Notes Part 1 

John Meersma, a Cisco Unified Communications Instructor at Sunset Learning Institute, put together a document he uses as a quick reference/study guide in his Cisco VoIP classes.

John found that when studying for an exam, or preparing to teach an upcoming class, it helps tremendously to write down commands and to summarize some important bullet points regarding the topics that he is learning about and memorizing.  Not only does this help him retain the information, it also works great as a reference when he is configuring IOS devices.   We hope that you will find these tips useful and informative.

 The Three Principles of Data Center Infrastructure Design 

Your data center is the most critical resource within your organization. As you know, it provides the means for all storage, management and dissemination of data, applications and communications for your business. When employees and customers are unable to access the servers, storage systems and networking devices that reside in the data center, your entire organization can shut down.  

In this blog post, SLI Instructor Tuan Nguyen discusses the three main principles of Data Center Design: Space Saving, Reliability, and Manageability.

 Subnetting Made Easy Part 2 – Variable-Length Subnet Mask (VLSM) 

Variable-Length Subnet Masking (VLSM) amounts to “subnetting subnets,” which means that VLSM allows network engineers to divide an IP address space into a hierarchy of subnets of different sizes, making it possible to create subnets with very different host counts without wasting large numbers of addresses.

This video is a continuation from the Subnetting Made Easy video previously recorded by Sunset Learning Institute. In this video, Sunset Learning instructor Russell Hughes describes what is VLSM, when you should use it, and finally demonstrates building your VLSM.
