You have to audit the SQI before and after enabling AMR, also you have to know what are the codecs used in case of AMR – FR or AMR – HR. AMR is a positive for speach quality specially in case of HR activated due to capacity issues. On the other hand, I noticed degredation in SQI and FER in case AMR was activated in a BSC with A-ter or A-bis through VSAT. Anyone noticed same problem with AMR over VSAT?
