I have been testing the MWI light on our Yealink T21P, T23 and T29 phones. After having read all the messages, my trace shows the NOTIFY traffic being sent to the devices and the devices 200 OK. For some reason, the light keeps flashing until I manually press a button turn it off on the device itself.
