   Parameter Length/Range Default Description Mode Change Neighbor NA NA This flag restricts the mode change of an AMR-WB to the neighboring modes in the Active Codec Mode set. Neighboring modes are the ones closest in bit rate to the current mode, either the next higher or next lower rate. If checked, the Egress offer/Ingress answer from SBC sets the Mode-Change-Neighbor value to 1. If unchecked, change between any two modes in the Active Codec Mode set is allowed. Initial Codec Mode as per 3GPP 26.114 NA NA This flag determines what is the initial codec mode of AMR-WB transcoded call, once the call is established. If unchecked, AMR-WB call starts with the highest rate in the active mode set. If checked, AMR-WB call starts with a rate determined by the following algorithm: If 1 codec mode is included in the mode-set, it should be the initial codec mode. If 2 or 3 codec modes are included in the mode-set, the initial codec mode should be the codec mode with the lowest rate. If 4 or more codec modes are included in the mode-set, the initial codec mode should be the codec mode with the second lowest rate.

7. By default, all the options of AMR-WB Mode Set are checked. To run the calls in a restricted AMR-WB Mode set, uncheck the modes that are not required in the Active Mode Set.
