trend or something local.
You aren't imagining things. In fact, some large national networks have been des
igned to support solely ethernet. It comes down to cost, as always....

Actually, a lot of people would be shocked at just how much VoIP is now
used to transport voice with TDM only occurring at the last mile and in
many cases at the last foot. Anyone designing a voice infrastructure
would be best to design it for VoIP. Your ROI is much much greater. If
you need to use TDM, then do so only at the edge as close to the TDM
equipment as possible.
Of course if you are going to use VoIP through-out an infrastructure it
certainly is a good idea to get familiar with QoS provisioning.
