Claim:
A method comprising: receiving, at a data-processing system, a first signal that indicates an unsuccessful call attempt from a first telecommunications terminal associated with a first user, the unsuccessful call attempt being addressed directly to a wireless telecommunications terminal associated with a second user, wherein the data-processing system is separate from the wireless telecommunications terminal; transmitting, in response to the first signal, a second signal that prompts the first user for a multi-modal condition of availability for a future call with the second user; receiving, at the data-processing system, a third signal that indicates that a second telecommunications terminal associated with the second user is available for the future call; upon receiving the third signal and while the multi-modal condition of availability is satisfied, transmitting, to the second telecommunications terminal, a fourth signal that (i) indicates that the first user previously called, and (ii) requests, prior to establishing a call between the first telecommunications terminal and the second telecommunications terminal, an indication from the second telecommunications terminal that the call be established; and in response to receiving, from the second telecommunications terminal, a fifth signal that comprises the indication, establishing the call between the first telecommunications terminal and the second telecommunications terminal.
