We have 7 companies across the globe and we have Avaya SCN through VPN connectivity. We have users who are getting the message INVALID BUTTONS when they use different avaya phoneset model from one office to another office. The only thing we can do is to delete the EXT number and recreate it. That time they can logged on with their extension properly. Please help on how to rectify this issue without recreating their extension number.
