I'm new to phone systems, but managed to setup new phones, voicemail, call groups and email on this SX-200ICP I inherited.
I want to enable MOH but I don't have a manual.
Where can I get an installers manual?

I tried www.quick-manuals.com, they don't have one for this system.
It identifies itself as SX-200ICP 2.0.4.33

thanks
