Check out these sites for more on voice technology
AT&T Tech Channel: This site is the official home for AT&T’s Archives. Despite AT&T not being the big company that most of America is familiar with; they have a dedicated staff that has since about 2011 posted on a regular basis film and video from the Bell System, to Bell Labs, to internal marketing videos and some productions from early 1990s in video format (they still used film as late as the mid 80s.) Most of the video embeds have come from these fine folks.
Flickr: Panel Switchman This account had some nice variety of photos from central offices to PBX systems from 1980s and before. The last activity was about 5 years ago and photos are still there.
The Avaya Engineer, a blog that focuses on Avaya Red enterprise systems with helpful hints on getting by on the said system.
PBXHowTos, is focused on mostly Avaya Red enterprise systems as well. A former Tier 3 support crew once based in Colorado, “CJ” has given people basic video tutorials on how to set up extensions, trunks etc on anything from an old Definity to the current “Aura” offerings. Like other sites, updates are whenever he feels like updating or will make promises, then not follow up. (He told me on his Facebook page last year that he was going to send me his G350 as he didn’t need it anymore…but that didn’t happen as dead air arose.)
For the Avaya Blue or Nortel nerds of the world, there is The Nortel Guy on YouTube, and he can train you in a crash course setting on Norstars and the large Meridian 1/Cs1000 systems.
Eli the Computer Guy, this oddball of a guy can actually give you some great crash course on telephony believe it or not. I recommend it because I feel his lessons are right on for that level for the IT types.
“PHUN” (or MISCELLANY)
Lorraine Nelson, also known as “The Voice of AUDIX”, or Avaya’s voice mail application. AUDIX has a strong brand (that of course dates far back in the days AT&T made hardware) because of the simple “Your Call is Being Answered by AUDIX.” Some people love her, some hate her, but hey she’s human afterall and hey how often do voice overs always read copy with a smile? Heh, heh?
The NH Telephone Museum: This is a nice place to visit if you are in Central New England. The museum claims to have nearly or more than a thousand artifacts that originally began as a collection of a former owner of an independent telephone company in New Hampshire’s Merrimack Valley. The Museum opened in 2005, and is a non profit operation. This place is loaded with tons of test sets, telephones from every generation, and other neat exhibits. As of 2015, they’ve added an exhibit featuring the personal computer, likely to get that younger demographic. I’ve been here once, and I’ll say I got lost for literally 3 hours.
