I'm trying to install a 64 button add on module to an iDCS 28B phone. The digital station port shows a 64B AOM is installed. I can't figure out how to program the buttons and have it work with the exetension (212). I don't see the AOM on the button program on Device Manager. It does show on the port programming.

Did you assign the AOM to the set in MMC 209?

Thanks John. I got it figured out. Was trying to do it thru device manager. When I went to telset program it was easier for me to figure out
