Does anyone know how to get rid off ERR047 frequently shown on TNs that have KEM on. It shows ERR047 77 0 0 11 1 0. According to Nortel, the explanation is TN 77-11 configured 1 KEM and number of responding from i24 KEMs is 0? I programmed KEM = 1 since I only one KEM attached to the phone and CLS KEM3 which is correct for 1140 phone?
