Is there a way I can progammatically call sendExecute api to tell an IP Phone to display a different font size/color/font style? My solution is responsible to send medical alert/text message to an IP Phone. Depend on the severity of the medical alert, I need to tell the phone to display a different font size/color/style to indicate high severity message. If not, is there a way we can configure the phone (either through the phone setting or CUCM) to display larger font size?
