I have been meaning to do this for a little while. I have finally managed to get some time to do it. Basically I have recorded two videos. The first is how to go about setting up a response group, using rgscot to create the contact object and then creating a workflow.
The second instalment is what a user will get when they call a response group. Apologies for the quality of the second video as I needed to cut it all together as I need to assume two personas, that of the user calling in and that of the agent answering.
All these videos and more are on www.ucsimplified.com
