      • 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

  • b742ef72528107d065e6ebc3c8cd413b   3_2_7_P315_firmware.eff

This firmware provides a change in default phone behavior. In previous versions, wildcard certificates for SIP TLS connectivity were not allowed by default, in accordance with SIP standards. Because this has created a problem in practice, we are reversing this behavior. For this firmware and forward, wildcard certificates will be allowed for SIP TLS connectivity.
