Abstract
Techniques for providing presence services to black phones are described herein. According to one embodiment, a call is received from a caller party to a called party, where the call is originated from a POTS device that is not capable of handling IMS protocols. In response to the call, a presence service provider is used to retrieve presence information about the called party using the IMS protocols, where the presence information indicates a current presence state of the called party. Then the current presence state of the called party is announced to the caller party by playing a prerecorded voice message representing the current presence state of the called party. Other methods and apparatuses are also described.
