Mitel Express Messenger can be set to allow guests to set their own wake-up calls. I believe that it's option 3 after login.

MAny hotels prefer this ove console wake-ups.

Vad has a point: that Messenger should not be removed while the status lamp is amber. It can be removed while green or red.

All ports should be programmed up before installing the card -- Have all of your replacement cards been of the same port count?
