I continue to be very impressed with Dan York and Jonathan Zar’s Blue Box VoIP security podcasts. Dan’s latest blog entry details some of their most recent shows, including a few special edition podcasts from our recent ETel conference. I especially liked Brad Templeton’s talk from ETel where his “evil twin” gave a sarcastic (and hilarious) talk to a fictional ILEC conference about the CALEA wire-tapping act. They’ve also got Phil Zimmerman’s ETel talk and an interview with Asterisk’s Mark Spencer and Ranch Network’s Alex Pavlovsky. If you’re working in VoIP security or just interested in staying on top of the current VoIP issues, you’ll definitely want to subscribe to Blue Box.
