NOTE: As I will explain in more detail on our next show (#37), there were a number of issues with the audio in this show both in the recording as well as in the post-production. One of the issues was some very annoying noise artifacts in the Endler/Collier interview that sound like cell phone interference. There are also a couple of gaps… and those with finally attuned ears will hear some clipping of the audio. Suffice it to say that I would not want our podcast to be judged by the audio quality of this episode! I’ll explain more in our next episode about exactly why this episode didn’t hit our usual quality level.

Telecom Junkies podcast on Pena/Moore VoIP fraud case

As we mentioned on recent shows, I (Dan) was a guest on a recent Telecom Junkies Podcast called “VoIP Fraud Sets Off New Alarms” where we discussed the Pena/Moore voip fraud case that we’ve been discussing on recent shows. Target audience was for “telecom managers” at large enterprises and is produced by the folks who create “The Telecom Manager’s Voice Report“.

The other guests on the show with me were Gary Meliefsky from NetClarity and consultant Ken Agress. Definitely a fun show to do and I appreciated the Voice Report folks having me on the show.
