The present invention provides flexible call processing. In one embodiment, a first call from a calling party intended for a called party is received at a call processing system. The call processing system places a second call to a telephonic device associated with the called party. The calling party and called party communicate via the first and second calls. A determination is made that the first call has been terminated. A call-back instruction is received from the called party while the second call is still in place. At least partly in response to receiving the call-back instruction, a third call is placed to a terminal associated with the calling party. The calling party and the called party can communicate via the second call and the third call.
