RADISYS CUSTOMER STORY | Improving VoIP Conference Quality
RSYSVOIP03122021A
Voice Quality Metrics
Technology to remove audio quality impairments in a VoIP
network is an important part of any solution. But service
providers also need a standard, objective way to measure
voice quality in order to accurately monitor performance
levels and uphold service level agreements (SLAs) with
customers.
The Radisys Media Server supports many voice quality
metrics, and they are divided into three groups: packet,
audio and acoustic echo cancellation (AEC). All statistics
are captured for each leg of a conference call to help with
granular troubleshooting of audio quality problems and
performance measurement. Packet statistics measure
performance with respect to packet throughput, loss and
delay, while audio statistics measure speech and noise power
levels. AEC statistics measure the echo delay and echo
cancellation performance.
