I am running CME v4.2(0) with IOS version 12.4(11)XW2, I have connected 7914 expansion module to 7941G IP Phone with firmware version 8.2.2TR2, the module is correctly configured but when the IP Phone is booting it detects the ephone-dn that are monitoring but at the end it says the message error:
****CHECK IF 7914 OPERATIONAL****
All the buttons are in red at all times, the status of the module in the IP Phone is not detected.
Maybe is the firmware, does anyone had this problem before that can help me on this??
