Thanks for the reply, I am a novice but have done some work such as add cards to increase the number of extensions and a bit of configuration through the installation tool. It was initially installed by a telecoms company in 2012, but suspect it was never new from the start. I always make sure I take a backup of the current configuration before I touch anything on it, just in case something goes wrong.

Where would I like on the device manager for the day menu and how would I check if the auto attendant or the phones ring first. At the moment through the web interface I can find the options for the auto attendant, 1 for sales, 2 for technical, etc.and they seem to point towards a station group under mmc 4.1.1. if no one answers it then points to another ring group sequentially.
