HD Voice with Andy Abramson
“High Definition Voice” on phone conversations is something you may not notice until you have experienced either very bad or very good quality. Andy Abramson of VoIP Watch will be joining our discussion of HD rollouts by [a carrier whose name begins with O] and the ramifications and challenges as he expressed them in his recent article.
On the subject of peering, we hope to hear from the XConnext about their efforts at being World’s First High-Definition Voice Peering Federation.

Freeswitch Today
Friday August 27th, 2010 Part 1
Podcast: Download
Audio : Download file (TS-386700.mp3)
Some intense examination of the requirement to tell people you are recording a call with the regulars while waiting for FS bridge to successfully UNmute it self. Note that ZipDX implemented the warning when you connect to the bridge if recording is on. Some reminders about *6 to toggle mute state.
The origin of “Look to your skies for a warning! Keep watching the skies!” Naw, I cut that part but I wanted to add the link in this post, because I didn’t get more info from FS about what to put here. Great movie, “The Thing from Another World”, featuring James Arness (“Gunsmoke”) as “The Thing”. One of the best science fiction pictures from the fifties, and one that helped define the genre.
From yet another world, (the Freeswitch bridge), Pacman sounds, and then belched forth the actual meat-space aural personna of the like of Brian West, Michael Collins, Anthony Minessale, Darren Schreiber and a few less-stellar voices…
From their site at Freeswitch.org: “Created in 2006 to fill the void left by proprietary commercial solutions. FreeSWITCH also provides a stable telephony platform on which many telephony applications can be developed using a wide range of free tools.
FreeSWITCH was originally designed and implemented by Anthony Minessale with the help of Brian West and Michael Jerris. All 3 are former developers of the popular Asterisk open source PBX. The project was initiated to focus on several design goals including modularity, cross-platform support, scalability and stability. Today, many more developers and users contribute to the project on a daily basis.”

The final part of the Freeswitch sessions. The ever-efficient Karl Fife wrings yet more tidbits of useful information from whoever was left on the Freeswitch bridge. This would have been in the fourth or fifth hour.
Freeswitch book is here. The official title of the book is FreeSWITCH 1.0.6, however don’t let the number fool you. The information applies to both FreeSWITCH 1.0 and 1.2 branches.
Dave Michels‘ son Dustin plays a mean guitar. Here’s Dustin Michels video.

Russell Bryant Q & A (and more)

Audio : Download file (TS-388692.mp3)
With everything up in the air, we weren’t sure they’d be a session, but I arrived back in time, so I should be there to talk about whatever anyone brings up.
By a bit of good luck, Russell Bryant stopped by and shared a lot of interesting details and answered question about what’s new with Asterisk. Russell is Engineering Manager for the Open Source Software team.
We later got into talking about the 3G used, unlocked and jailbroken iPhone I bought in the USA and broght back to Europe without knowing how it would work. I was saying that in California, the iPhone showed my location to withjin feet without data or wifi connection, as long as the map was already loaded (using wifi at home). That brought us to GPS and how it works. Here in France, the location it finds is much less accurate.

This coming Friday, August 13th will be yet another Voip Users Conference double-header. Starting at our usual 12 Noon EDT we have an overview of the Freetalk Connect SMB PBX featuring Skype integration.
Then immediately following, at 1pm EDT, we have Chris Veazey, VP Engineering of Blink Mind, to discuss the current state of the industry with regard to multi-media phones and SIP-based video calling.
Blink Mind has agreed to provide a video conference bridge (MCU) as part of their appearance. Further, as Blink Mind are a Polycom partner, Polycom has graciously provided a pair of Polycom VVX-1500 Business Media Phones on loan. One VVX is at Randy’s location in California, and the other in my home office.
As we aim to explore the capabilities of the VVX-1500 and similar desk phones, the video portion of the Blink Mind call with be limited to CIF (352 x 240) resolution using H.264 compression.
