As well as having a red light on the intercom button is on and there is a
continual one ditty played over and over again.
I can only get rid of it by dialling 9 for a line out.

Under my Intercom light I have a green light (7731,7735). I'm not sure why yours is red, but here are a couple of things to try.
Press "1" on the keypad without picking up the handset. That turns off Background music and the display will say BGM On or Off.
Press Intercom or pick up the handset and dial 790. That's the extension reset code.
If neither one of these work, post back with the model number of the phone system cabinet the phones are plugged into. It's probably a Panasonic TA-624/824 but there's a chance yours is different.
