You use the emergency-dscp-profile configuration element to define DSCP values to match within a SIP INVITE. The SBC drops matching INVITEs if they do not also include separate SIP designation as emergency traffic. If configured, the SBC sends the error code and message you set in this profile. If you do not configure an error code and text, the SBC sends the default SIP error code and message “403 Unauthorized attempt to use reserved resources”.
