Abstract
Methods, devices, and systems enable a server to route a communication from a calling party to a third-party device when a called party is unreachable by obtaining current status data from a plurality of devices registered with the server, and generating a list of potential third-party devices based at least on the obtained current status data. A call request notification may be transmitted to a third-party device selected from the list. In response to receiving a call acceptance message, the server may transmit an authentication challenge for the called party. The server may determine whether an authentication response message includes a correct response to the authentication challenge, and if so, administer the communication between a calling party device and the selected third-party device. The server may calculate charges to the calling party or called party and credits for the third-party whose device accepts the communication for the called party.
