- My MITEL/AASTRA sidecar has power but is not displaying as an option in the Keys menu.
- When I press the Keys menu, I see top and bottom options but not the expansion module option.
- Disconnect all power to the phone and all cables.
- Verify the sidecar is properly seated and has the correct screws to hold it tightly connected with the deskphone.
- Once tightly screwed and seated, please power the phone back and try again.
