Need help - inherited a Norstar CICS system and have successfully connected up in-lines and extensions. However incoming calls are not ringing on phones - line 1 lights up ok (flashes) and line can be picked up - also ringers work dialling other extensions - but phones are silent when calls coming in. Also would love to know of a software way to change extension numbers - there is no change DN in system config/system progamming for ICS.
