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 better. 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. _______________________________________________ Discuss mailing list Discuss@blu.org http://lists.blu.org/mailman/listinfo/discuss
