Methods, systems, and computer-readable medium to perform operations comprising determining a plurality of metrics of data trafficked through a session border controller (SBC), the SBC in communication with an endpoint device and positioned along a data transmission connection between a network and a IP multi-media subsystem (IMS); detecting a packet loss performance metric of the data; in response to detecting the packet loss, determining that a retransmission of the SBC is degraded; in response to determining that the retransmission of the SBC is degraded, determining that an endpoint network response time (NRT) is degraded; in response to determining that the endpoint NRT is degraded, determining that an endpoint signaling response time (ART) is degraded; and in response to determining that the endpoint ART is degraded, identifying the endpoint device as a root cause of the packet loss performance metric of the data.
