Reply To: EFR vs AMR FR



EFR and AMR FR “12.2” provide the same voice quality because it is exactly the same codec.

Why do you want to force EFR rather than AMR FR ? All MS can support EFR, so your question should be :
“How to forbid usage of AMR FR ? … How to force all MS in EFR only”

… just disable AMR FR ! 🙂
