Step-by-Step Guide to Configuring Extension Mobility

In my day job, I support a company that has extension mobility configured across many locations. We see a variety of problems that occur - mostly from misconfiguration (we didn't install it :) ). The following step-by-step guide is a great checklist if you're unsure about an existing extension mobility configuration, or if you are planning to install extension mobility for the first time.

The video below from SampleFive does a very good job of illustration the steps listed.
