i nv use VoLTE b4, but i dont think it is free.
coz u r using their framework to connect to another telco.
traditionally voice channel is limited to 8bit quality,
if u wan more bit, voice channel unable to provide u... tat y they use data channel in LTE.
so what does 8bit audio or more mean...
8bit - suitable to carry human voice data
16bit - music... voice+treble+bass like ur mp3 quality
24bit - music + more background sound... eg singer stepping on the floor sound (aka dancing) is recorded
in conclusion, if u r using VoLTE.. ur spouse will know whether u r cheating or not... they hear everything in background.
noob here...but RN5 got noise cancelling?does the background sound still can be heard?
