ETel Coverage: Mark Spencer on the Future of Asterisk
March 02 2007
Jim has already beat me to writing about Mark Spencer’s talk on the future of Asterisk. A prior ETel presenter had noted that presentations in Japan begin with an apology. Mark is planning a trip to Japan in May, and began by apologizing for the voicemail system, and the queue/agent… read moreMarch 02 2007
One of the biggest draws for me to attend ETel was the Neo1973 and OpenMoko. My dissatisfaction with Apple for the closed platform on the iPhone means that I’m looking for an alternative. In addition to the “pure” interest I have in an open, customizable platform, I recently attended the Education… read moreETel Coverage: Space, Time, and the Context of Internet Telephony
March 01 2007
Today, Moshe Yudkowsky talked about revolutions and what causes them. His basic contention was that revolutions result from taking systems apart to separate concepts or structures that were previously bundled. That may be in the area of authority (such as the way that user-generated and selected content led from static… read moreETel Coverage: Funniest demo ever!
March 01 2007
Summer Bedard of NYU’s ITP program just showed off an Asterisk-driven queue program. Queue managers aren’t really that interesting because most of them operate on a FIFO basis, perhaps with levels of priority for a few different classes of service. In this queue manager, callers compete with each other for… read moreI wish Apple had taken on the telcos

Anything that threatens the sacred cow of metered business, whether it’s minutes or bits you’re metering, is something that needs to be blocked at all costs by the telcos. Fortunately, the structure of the American mobile telephone industry gives them a solid way to play defense. Carriers buy the phones… read moreHooking up Skype to Asterisk via SIP
October 30 2006
So far, the success of Skype within their walled garden of VoIP has been quite impressive. One of the more interesting things I’ve learned from my travels is that Skype is extremely popular in Asia (at least outside of Japan) so much that in many places, “Skype” is synonymous with… read moreFree telephone numbers with Internet Telephony Administrative Domains (ITADs)

One of the reasons that I was late to VoIP was that the initial services just weren’t that exciting. (To be fair to myself, I probably wasn’t really that late. I just feel like it sometimes because so many of my friends were first-wave early adopters.) Another way to connect… read moreExtending MythTV recording space with LVM
May 13 2006
I dearly love my MythTV system. I travel a lot, and it enables me to take TV with me to 35,000 feet. What I love best is that it’s growing with me. I recently added an Air2PC HD5000 card, so I now have a three-tuner box. (I hope to write… read moreQuality of Service for Voice on the Interop Show Floor
May 05 2006
A month ago, I was staging the Interop Labs, with a particular personal focus on VoIP on 802.11. At that point, I promised to investigate what improvement Wi-Fi Multimedia (WMM) prioritization makes to voice quality. The Interop show floor is a terrible radio environment. From the Interop Labs booth, I… read moreRecording the Interop voice samples in Asterisk
May 05 2006
To record voice samples for the WMM comparison in my last post, I set up Asterisk for recording. I wound up using two approaches to this: a star code (*8) to preface extensions that indicated the call should be recorded, and an interactive voice demonstration. First, the star code: by prefacing… read moreRecent Posts | All Posts
