i just mean that if the codec chosen for a call is AMR (in one of the 2 MS), then TFO is deactivated for that call.
They don’t work at the same time on the same call.
If the call is using legacy codecs (EFR, HR), then the TFO can be activated.
The parameter to choose what you favor is “FORCE TFO VS AMR”
In B11, AMR and TFO can work together during the same call (when 1 MS adapts its DL Codec, for example, then the other MS is forced to adapt its UL Codec, so that TFO can be maintained)
