hi guys im in a fix. got sent on a job installing a new ip office. 201 and 202 are nortel sets, and 203 and 204 are avaya cordless sets on nortel lines. one is working fine the other was saying it wasnt connected to the ksu. i moved it to another pair and now it doesnt tell me it isnt linked to the ksu but the buttons wont work. the company that sent me checked and assured me the buttons are progarmed. the sets have id set and are regestered. i do get both extensions at the jack that feeds the base. it is going to the tcm 4 port of the base with an 8 conductor patch cord. any ideas. thanks dave
