Presenting at Interop NewYork, Sept 17

Terry Slattery
Principal Architect

I’m doing my presentation titled Troubleshooting Converged VoIP and Data Networks at Interop New York on September 17 at 1:30pm.  The session title is Troubleshooting Converged Networks.  It has been a well-received topic at prior VoiceCon shows and speaking at Interop gives me the opportunity to share the same information with a different audience. According to Eric Kraph, it is one of the best attended VoiceCon sessions, so we’re expecting good attendance at Interop as well.


I came up with the idea for the presentation while attending several trade shows.  I saw a lot of vendors talk in general terms about their products but there was seldom any useful information that the attendees could take away to help them in their network (at least without buying the vendor’s products, which is really why vendors make such presentations).  When you only have 15 or 20 minutes to speak, it is difficult to provide substantial content and also differentiate your products.  So I looked at it from a different angle.  What if I selected a set of typical VoIP problems and discussed the cause of each, giving the attendees a list of things that they could check in their VoIP deployments.  If I’ve given some portion of the audience information that that they can use to improve their network, then I’ve given them an idea of the types of problems that NetMRI detects.

My talk covers a variety of topics across the spectrum of problems in a VoIP deployment.  I start with basic connectivity problems, call registration problems, and describe problems of calls in progress.  Finally, I talk about other potential problems like inconsistent music-on-hold and what causes it.

Sure, NetMRI detects a lot of the problems I describe – I hope that’s obvious.  If the attendees find something useful out of my presentation, I hope that they’ll come look at NetMRI as a way to help them automatically find and fix a lot of their VoIP problems.
