| on the 3750 you need a analogue a/b card to have a fax on the system or else get a analogue adapter that connects to the bottom of a standard or advanced telephone and will work as a separate extension.
This terminal adapter is for ISDN. You need to set up ISDN extension on the system ( this requires a ISDN card with a spare port)
Are you using basic rate ISDN or pri or analogue lines? |
