Our two UC Specialized Instructors, John Meersma and Maren Mahoney created resources to showcase new features in Cisco Unified Communications Manager 9.0. We have a document that lists out new features and a pre-recorded webinar demonstrating features available in CUCM 9.0
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.
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.
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.
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, 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.
John Meersma, a Cisco Unified Communications Instructor at Sunset Learning Institute, has put together a series of notes he uses as a study guide during training and also as a quick reference guide. This is Part 2 of his voice notes, focusing mainly on GWGK Commands and other Notes.

ACI is Coming. Are You Ready? A Recorded Webinar from Sunset Learning Institute
SDN is an inevitability, but Cisco’s ACI goes beyond SDN with an application-aware infrastructure that simplifies the management of fabric, application deployment and security through a common policy framework. Companies save money, time and precious resources. As a result, many large organizations are moving to an Application Centric Infrastructure.
As a Network Engineer, how can you leverage your existing expertise in the burgeoning SDN landscape? What skills remain relevant and what do you need to understand?
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.
