"Wake up Easy" is the first sip based application in the world that registers as an extension to a Voip/IP PBX system and is working as a wake up call service for your customers. It is a necessary service for hotels that use VOIP/IP PBX systems. There are three ways to activate a wake up call. Fast Activation: Make a call to the Wake up Service. When the welcome message begins to play, just type the time you need the service to make a call back. In case a user/customer needs to put an alarm time at 07:01, the only thing they should do is type "0, 7, 0, 1, # ". The Wake up easy Service recognizes the "#" as a save command and stores the wake up time. After that, it plays a success message and hangs up. Normal Activation: The user of the service just follows the instructions that are heard until an alarm time is activated for him. In this case also, a success message plays before hanging up. Wake up Call Cancellation: The only thing you have to do is ring the service. The Wake up Service will recognize the CID (Caller ID) and automatically cancel the alarm. After the Cancellation, it will play the corresponding message. Web Activation: Using the Web Interface you can activate and manage alarm for your customers/guests. The web interface has a password protection, so only your staff are able to use it. Any alarm that has been activated by the Web Interface can not be canceled from your customer/guest but only from your staff who is using the web Interface. More here http://www.sipservices.gr.
