RTP_PAYLOAD_MAP

This structure associates an expected payload ID for incoming RTP packets with an endpoint type. Use RTP_PAYLOAD_MAP with the MSP_CMD_RTPFDX_MAP command, which can be sent to video RTP endpoints.

typedef struct tag_RTP_PAYLOAD_MAP
{
    DWORD    vocoder;
    DWORD     payload_id;
} RTP_PAYLOAD_MAP;

For video endpoints, use the following values in the vocoder field:
