Blue Box #38 coming soon… and if you are at Fall VON, let us know

Well, we recorded Blue Box #38 last week, but Jonathan was in Asia and we had some connectivity issues which required more post-production than I could do before leaving for Fall VON.   It will be out, soon, though.

Also, if any of you are here at Fall VON 2006 in Boston, please do drop us an email. I (Dan) am at the show and will be on a panel of VoIP bloggers tomorrow at 1:30pm Eastern.  I’ll also be doing some interviews which I intend to put up as a special edition.

Stay tuned for more…

New comment line number – +1-206-350-2583

While K7.net provides a very nice voicemail service for free, one of the disadvantages of using the service is that if no one calls your number in 30 days, the number is made inactive and there is no way to start using it again.  In periods where we have had no audio comments for some time, I have tried to remember to just call it myself… unfortunately, I didn’t do so recently and so we lost the number we have been using since October 2005.

The new comment number is +1-206-350-2583 ("2583" = "blue" – cute, eh?) Please do give us a call and let us know your thoughts on the show.

(And yes, in the recording of show 36 we still mention the old number – I unfortunately discovered the problem after uploading the already post-produced show 36.)

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.

If you are attending Black Hat this week, let us know…

If any of you are heading out to Las Vegas for the 2006 Black Hat Briefing tomorrow and Thursday, please do drop us a note as we’d love to connect with listeners. Jonathan and I will both be out there in part because there is a “voice security” section to the conference schedule but also because with David Endler attending (and speaking), it is a good chance to catch up on VOIPSA issues.

Blue Box #34 pushed to next week

Well, I gave it a valiant try, but the lesson of this week is that I have to either: 1) wipe and re-format my laptop; or 2) figure out another way to do post-production while travelling.  When trying this week to edit the recording Jonathan and I did right before I left for IETF, my laptop kept entering a state of doing an insane amount of disk swapping… and not letting me get the editing done.  So, I’m unfortunately going to have to delay it until I get back home and can use my normal system there.

The good news for you all is that you will wind up with two Blue Box podcasts next week.

BTW, the IETF meeting was excellent… if you haven’t gone before, I’d definitely consider it for future meetings!
