Patent ID: 8611516

Claim:
A method for establishing a communication transmission comprising: detecting an original signaling going out from a first terminal having a sender address and directed to a second terminal for attempting to establish a connection in which at least audio data having voice data is transmitted, wherein the second terminal is addressed by a target address assigned to the second terminal; detecting additional signalings from the first terminal with the sender address specifying the first terminal and the target address assigned to the second terminal that are additional attempts to establish the connection with the second terminal; determining a first amount of time that is defined by a time that passes from when the original signaling was detected to when a latest detected one of the additional signalings was detected and comparing that first amount of time to a first preset time period, wherein the first preset time period is a maximum amount of time between detection of the original signaling and a detection of the latest one of the additional signalings; upon a determination that the first amount of time is less than the first preset time period and upon a determination that the detected number of the additional signalings is greater than or equal to a preset value, a switching unit rerouting the latest detected one of the additional signalings so that a third terminal is contacted to establish a connection with the first terminal in which audio data having voice data is transmittable between the first and third terminals; upon a determination that a time difference between the latest one of the detected additional signalings and an additional signaling of the additional signalings that was immediately prior to the latest one of the detected additional signalings is less than a second preset time period, the rerouting of the latest one of the detected additional signalings being actuatable; and upon a determination that a time difference between when the latest one of the detected additional signalings was detected and when an additional signaling of the additional signalings that was immediately prior to the latest one of the detected additional signalings was detected is greater than the second preset time period, the determined number of additional signalings being counted such that no rerouting of the latest one of the detected additional signalings occurs.
