Wake Up Call on ISR 2851

Hello
One of my customer is requesting a wake-up call feature for a few hotel rooms they have at the meeting center.
Setup is a Cisco ISR 2851-CCME-K9 with 68 phones (12 need wake up call). 2 HWIC ISDN cards, 1 Analog 4 FXS card, There is no CUE card (no voicemail) and no other options on ISR.
Can someone recommend a solution so that the receptionist can program a wakeup call ?
Idealy it should ring the room and play a nice message when picked up.
In advance, Thank you
Fab

You could build it with Unity Express IPIVR option
I'm not aware of a package out there that does this yet, but I could see building it with the IPIVR option on Unity Express.
You would need a separate database / Web server as well.
a bit of canned text about IPIVR follows. . .
Cisco Unity Express Interactive Voice Response (IVR) allows a telephone caller to select options from a voice menu and otherwise interact with the system. After the system plays a prerecorded voice prompt, the caller presses a number on a telephone keypad to select an option. The Cisco Unity Express IVR applications work with Cisco Unified Communications Manager Express or Cisco Unified Communications Manager to provide small- and medium-sized companies the ability to enable callers to run queries to gather information from a customer database and to control the information stored in the database, confirm orders placed using the IVR application by sending outgoing e-mails or faxes from within the IVR application, and use incoming HTTP request-based trigger applications to initiate IVR applications to send an e-mail, fax, or phone call notification that an order has been filled and shipped.
