I've read and listened and a, fully aware of how VoLTE works, thanks. We were discussing the fact the Verizon currently doesn't fall back VoLTE calls to CDMA and what was require to fix this. You however,
made a claim, here, that Verizon is fixing the VoLTE to CDMA fallback issue with a carrier update and that it is in the beta stage, and that Verizon users can opt in. None of the links you've provided support your assertion.
Alpha male tactics don't hide when people make a claim they can't substantiate. Where is this info about a beta carrier file that you claim is available? Or did you just pull that out of thin air?
Perhaps it's best if you went back to not posting in boards like these.
