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.

    the issues will happen
  • Best Practices and testing
