Scenario 3: Solve VoIP Performance Problems Faster
A network management team for a large manufacturing organization is responsible for managing VoIP performance. To quickly identify VoIP problems and pinpoint underlying network issues, the team needs access to VoIP application performance metrics such as call quality and call setup.
Approach:
1) The NetQoS Performance Center reported that call quality for calls between Raleigh and Austin degraded in the last hour.
2)
After determining that the issue primarily concerned calls from Raleigh to Austin, the NetQoS VoIP Monitor Call Metrics detail report revealed that packet loss rose in the last hour, while MOS degraded.
3) Further investigation into performance problems on the Austin/Raleigh link using NetQoS ReporterAnalyzer™ showed that VoIP traffic dropped to the default “best effort” class of service instead of the “platinum” class VoIP requires.
Resolution
In unrelated network maintenance VoIP traffic was inadvertently misconfigured to the default class of service, resulting in packet drops.
To correct this issue, the converged voice group reinstated VoIP quality of service policies on this interface to the “platinum” class. This restored VoIP traffic to the correct priority, resolving VoIP call quality problems quickly.
