• Media Loopback Code (*03)—A service provider can set up a test call from
an IP media loopback server (the source) to a subscriber VoIP device (the
mirror). The test call provides statistical reporting on network performance
and audio quality.
Depending on the source capabilities, a service provider can see packet
jitter, loss, and delay (although Media Loopback cannot identify an offending
hop). This helps the service provider identify an offending hop that could be
causing issues in VoIP calls to a subscriber. The test results can also provide
audio quality scoring, that lets a service provider better understand the
subscriber's experience.
