One of my 9640G phones decided to stop getting dial tone when the Speaker Button is pressed. The button just turns red.
All of my other phones select line A and have dial tone when the speaker button is pressed.
I have cleared the phone and reprogrammed the IP settings.
I have removed the user and removed the extension and saved configuration and then recreated them from scratch.
I can't find any information about programming to change this.
I think I may have a defective phone.
