I think we often forget just how much of a massive inversion the

I started working in networking, everything was DS0 voice channels,

really understood or wanted to sell to. At the time, the volume of money
being raked in from those DS0/VGE channels was mammoth compared
to the data networking side; we weren't even a rounding error. But as
the
roles reversed and the pyramid inverted, the data networking costs didn't
rise to meet the voice costs (no matter how hard the telcos tried to push
VGE-mileage-based pricing models!
Haha, when I was at Cisco in the late 90's and was working on VoIP stuff
we were working with Sprint trying to get them onboard for a residential
voice project. They were really insistent on using AAL2 to conserve
bandwidth. I told them at the time that the bandwidth for voice was
going to be insignificant and it wasn't a big deal that RTP wasn't as
efficient. They looked at me like i had leprosy with body parts falling
off. Like the next month it was announced that data had surpassed voice
for the first time. We didn't get the contract, fwiw. But they never
launched anything either. Was there ever any significant deployment of
AAL2?
