The phones have directions to call the pilot number of 555. I am not sure about which port is defined to be used for MWI on/off. I can check that as well. I have to find out if we have a DNIC coming in. The one thing thaat did happen when I called the SS, it showed 303 and then all lines after that. I need to try the call to a room, with the SS plugged into the port, should it show the digit string with the transfer to MBX code, or will it just show what ext is calling the VM?
