I am trying to setup a third MOH port using an available CO port on the system. This is a Mach 1 FP3 and I have 12 CO ports with 1-8 in use and currently ports 9-12 open. According to the book I should be able to access System Parms with Flash 09 and program MOH channels 3-8 via buttons 13-18, btw I am accessing system via serial port so I am using the appropriate conversion and when I put in any of those button options the system does not recognize the entry. If I print System Parms and view the Music channels it looks like this: MUSIC CHANNEL[3..8] CO - 255 255 255 255 255 255. Any help on this would be appreciated, thanks.
