Configuring voice tests
NOTE:
Do not perform voice tests on known ports, ports from 1 to 1023. Otherwise, the NQA test might fail
or the
corresponding services of these ports might be unavailable.
Voice tests of an NQA test group are used to test voice over IP (VoIP) network status, and collect VoIP
network parameters so that users can adjust the network.
A voice test performs the following procedure:
1. The source (NQA client) sends voice packets of G.711 A-law, G.711 μ-law or G.729 A-law
codec type at regular intervals to the destination (NQA server).
2. The destination affixes a time stamp to each voice packet that it receives and then sends it back to
the source.
3. Upon receiving the packet, the source calculates results, such as the delay jitter and one-way delay
based on the packet time stamps. The statistics reflect network performance.
Voice test result also includes the following parameters that reflect VoIP network performance:
