Abstract: Devices, systems and methods for communications that include social media clients are provided. In particular, a server operates a virtual client for communicating with clients of a social media server. The server receives a call request associated with a directory number of a call server, the call request to initiate a call associated with the directory number and a given client of the social media server. The server conducts the call by controlling: the virtual client to communicate with the given client, via the social media server; and the virtual client to communicate with a communication device associated with the directory number, via the call server. The server may also facilitate exchange of status updates between a given client of the social media server and the call server. The server may also facilitate calls between respective clients of different social media servers.

Abstract: A system and method for routing selected phone calls to a user having a plurality of communication resources is disclosed. Background information of a caller is identified. A context of the user is postulated based on available information. The user's communication resources are identified. A location of the user is estimated. A cascaded ringing program for routing the phone call to the user is identified based on the background information of the caller, the device type of the user's communication resources, the postulated context of the user, and the estimated location of the user. The phone call is then routed using the cascaded ringing program.

Abstract: A method is provided for tracking the physical location of IP phones and IP devices in a network. According to the invention, the IP phone or IP device detects its own current location and then informs the PBX controller or the location database to which it is connected. The capability is integrated in every IP phone and IP device. The PBX or location database then takes appropriate action, such as updating the ALI mapping for the phone or location information for the IP device.
