Introduction

This specification includes recommendations for VoIP codecs as well as protocol configuration to enable efficient support of VoIP over HRPD Rev A and HRPD Rev B. VoIP codecs are chosen from existing 3GPP2 technologies 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-authorized access for VoIP emergency services.
