CHALLENGE
Dropped calls, choppy calls, loss of dial tone and voice delay are the typical problems your customers experience as a result of your network issues. Following are some typical contributing factors:
  • Jitter, Packet Loss and Latency
  • Network misconfigurations
  • Issues with Interconnection provider network
IMPACT 
Consistent poor voice quality increases customer churn rate directly impacting the revenues and service reputation. Voice quality issues increase support call volumes forcing service providers to realign resources from other productive tasks.
DESIRED SOLUTION
Granular visibility to critical voice traffic attributes in realtime helps in effective root cause analysis (RCA). Proactive monitoring and troubleshooting of issues reduce the impact of poor voice quality. You need a voice quality measurement solution that includes:
  • Real-time measurement of Media KPIs, such as RTP Jitter, Packet loss
  • Correlation of Voice traffic attributes with other network attributes
  • SIP/RTP Timing Analysis on origination & termination networks
