CELP compression - the stuff that sounds bad, and sounds doubly bad if
you ever listen to music through it - was part of the standard until
VoLTE came along. LTE-based calls use better codecs that sound much

The problem is not back end bandwidth, it's over-the-air bandwidth.
Non-LTE calling is done using inefficient protocols that use a lot of
it. IP calling over pre-LTE data standards isn't feasible because
their latency is too high.
