G.5 Configuration Optimisation

28.0623GPPInband Tandem Free Operation (TFO) of speech codecsService descriptionStage 3TS

The following protocol flow shows the example where only the local side needs to change its AMR Configuration (the ACS) to the optimal configuration, while the distant side has this optimal configuration already (shown here), or does not need or want to change. Typically this optimisation takes place immediately after TFO setup and is triggered by the TFO Report to the BSC or the TFO Report to the SMSC.
