I found an interesting and hopefully useful on-Demand Webinar with a PowerPoint presentation this morning: Microsoft Lync: Integrating with or Replacing Cisco. You can download the slides from: http://www.slideshare.net/perficientinc/lync-integratingciscowebinaroctober. The Webinar itself is on: http://www.perficient.com/Thought-Leadership/On-Demand-Webinars/2013/Microsoft-Lync-Integrating-with-or-Replacing-Cisco.
The webinar was held on June 13 this year, looks at the best ways to leverage Lync in addition to an existing Cisco infrastructure. Based on years of integration experience with Microsoft UC and Cisco, the webinar shares best practices and recommendations for getting the most out of Lync. This event gave attendees clear ideas of what works, what doesn't, and how best to bring UC to your organization.
Around 1/3 of the slides are advertising for Perficient, but the rest of the presentation looks pretty straight forward and it provides some good information.
Hope it’s useful!
