Voice and Data Cross Training--
Essential for Success in Convergence

You can buy voice and data technology that fits your needs,
but who will keep it running after two worlds converge?


If you outsource your entire voice and data infrastructure, you still need internal monitors to supervise the vendor.  If you "do it yourself" and run a private network with dedicated call servers, you'll need more people who understand convergence.  Where do they come from:  the voice side or the data shop?

The short answer is "Both."  Traditional skills and culture of either side, alone, will miss some key points and leave your converged network at risk for poor data performance and bad voice quality.

This seminar shows each person what the other has to contribute, explains the different jargons, and relates what is known to what is new so it's more easily remembered.  The goal is a team that understands and appreciates all of traditional data and voice so the converged system delivers the best of both. 

Flanagan Consulting presents this seminar in the Sterling, VA office over two days.  Or we bring it to your site, for 6 to 12 participants, over one to two days.  Printed notes give each attendee a permanent reference.  Call or email for costs and scheduling.
