VoIP codecs are chosen from existing 3GPP2 tech
32、nologies keeping in mind system efficiency as well as quality considerations. Recommendations are provided for transport protocols as well as for 3GPP2-specific system parameter settings for RoHC, RLP and RLMAC. A pre-configured provisioned session is also defined for use in supporting non-authorize
