The various embodiments include methods, computers and communication systems for establishing a closed feedback loop across multiple heterogeneous networks within a telecommunications system, which may include measuring a first attribute of a communication in a first telecommunications domain and sending a first request message including information relating to the measured first attribute to a server. The server may receive the first request message, identify a second telecommunications domain involved in the communication based on information in the first request message, generate a second request message that includes information for adjusting a second attribute of the communication, and send the second request message to the second telecommunications domain. A computing device in the second telecommunications domain may receive the second request message and adjust the second attribute of the communication to alter the first attribute of the communication in the first telecommunications domain.
