    • Alert-Info-Speaker-Volume=(1-10) - ignore local device speaker volume setting, and use the value in this header

    • Alert-Info-Interrupt=1 - Automatically put any current call on hold, auto-answer the call and play audio through speaker or through headset if it's already off-hook, similar to what is done with the priority and interrupt options of multicast
