I managed to somehow override the programming of a 7433 thats connected to a TD500 Pabx. Now I cant reallocate the CO lines to the CO buttons. Also I am unable to call any extensions, it displays NOT VALID. Previously the 7433 extension unit had been allocated three numbers 750, 751 and 0 but now only 750 works. Can anyone help me in restoring my settings? Will appreciate any help.
