VOS3000 ASR ACD Analysis Complete Configuration Easy Guide

What is VOS3000 ASR ACD Analysis?

VOS3000 ASR ACD Analysis is a powerful call quality monitoring system built into VOS3000 softswitch that enables VoIP operators to measure and optimize their network performance. ASR (Answer Seizure Ratio) measures the percentage of calls that are successfully answered, while ACD (Average Call Duration) tracks the typical length of completed calls. These metrics are essential for wholesale VoIP providers, call centers, and telecom operators who need to monitor route quality and vendor performance in real-time.

Understanding ASR ACD analysis is critical for any VOS3000 administrator. As we covered in our VOS3000 Softswitch FAQ, proper monitoring of these metrics can significantly improve your platform’s profitability and customer satisfaction.

⚙️ VOS3000 ASR Parameters Configuration

The VOS3000 system provides several key parameters for ASR calculation and routing optimization. These parameters are located in Softswitch Management > Additional Settings > System Parameters section of the VOS3000 management interface.

📋 Key ASR System Parameters

Parameter Name	Default Value	Description
SS_GATEWAY_ASR_CALCULATE	Off	Enable real-time ASR calculation for gateways
SS_GATEWAY_ASR_RESERVE_TIME	600	Length for gateway’s ASR routing in seconds (300-86400)
SS_GATEWAY_ASR_RESERVE_SEPARATE	10	Section count for ASR routing calculation (5-24)
SS_GATEWAY_ASR_ROUTE_SORT_CONFIG	Before line usage	Position for routing gateway’s ASR routing

💡 Pro Tip: The system divides ASR calculation into several time periods based on SS_GATEWAY_QUALITY_RESERVE_SEPARATE and SS_GATEWAY_QUALITY_RESERVE_TIME settings. For example, if SEPARATE is 10 and RESERVE_TIME is 600, each ASR period is 60 seconds, and the ASR at any point is the mean of the last 10 segments.

Average Call Duration (ACD) is equally important for understanding call quality and customer behavior. Low ACD values often indicate route quality issues or inappropriate traffic filtering. Configure ACD parameters properly to ensure accurate call analysis.

📋 Key ACD System Parameters

Parameter Name	Default Value	Description
SS_GATEWAY_ACD_CALCULATE	Off	External dial plan method for ACD calculation
SS_GATEWAY_ACD_RESERVE_TIME	600	Length for gateway’s ACD routing in seconds (300-86400)
SS_GATEWAY_ACD_RESERVE_SEPARATE	10	Section for ACD routing calculation step size (5-24)

🔄 ASR ACD Routing Strategy Configuration

VOS3000 allows administrators to configure intelligent routing based on ASR and ACD metrics. The routing strategy can be configured at the gateway level, enabling automatic route selection based on call quality performance.

📋 Routing Strategy Options

Strategy Type	Description	Best Use Case
None	System default routing	Basic configurations
ASR	Sort routes by Answer Seizure Ratio	Quality-focused routing
Lowest Rate per Second	Sort by cost efficiency	Cost-optimized routing

The First Routing Strategy and Second Routing Strategy can be combined for optimal results. When configuring gateway settings, enable “Calculate routing quality in real time” to activate dynamic ASR-based routing. This feature works in conjunction with the prefix settings explained in our VOS3000 prefix configuration guide.

📊 ASR ACD Analysis Reports in VOS3000

VOS3000 provides comprehensive reporting capabilities for ASR ACD analysis. These reports can be generated automatically or on-demand, providing valuable insights into gateway performance and traffic patterns.

📋 Available ASR ACD Report Types

Report Parameter	Default	Description
SERVER_REPORT_GATEWAY_CROSS_LOCATION_ASR_ACD	Off	Auto generate gateway cross area ASR ACD analysis report
SERVER_REPORT_GATEWAY_MAPPING_ASR_ACD	Off	Auto generate mapping gateway connect analysis report
SERVER_REPORT_GATEWAY_ROUTING_ASR_ACD	Off	Auto generate routing gateway connect analysis report
SERVER_REPORT_GATEWAY_MAPPING_LOCATION_ASR_ACD	On	Auto generate mapping gateway area analysis report
SERVER_REPORT_GATEWAY_ROUTING_LOCATION_ASR_ACD	On	Auto generate routing gateway area analysis report

📉 Understanding Analysis Report Metrics

Each ASR ACD analysis report contains several key metrics that help administrators understand their network performance:

• 📞Total Calls: Total unconnected and connected call attempts
• ❌Fail: Unconnected calls count
• ✅Success: Calls with connect/busy/no answer/ringing signaling
• 📱Answered: Calls with connect signaling only
• ⏱️Average Call Duration: Mean duration of answered calls
• 📊Total Call Time: Cumulative duration of all calls

🔔 ASR ACD Alarm Configuration – VOS3000 ASR ACD Analysis

VOS3000 includes built-in alarm functionality to alert administrators when ASR or ACD metrics fall below acceptable thresholds. These alarms help maintain quality standards and identify problematic routes quickly.

📋 Mapping Gateway Alarm Types

Alarm Type	Description
Mapping ASR	Alert when ASR falls below threshold
Mapping ACD	Alert when ACD falls below threshold
Mapping Concurrency Decline	Alert on sudden drop in concurrent calls
Mapping Gateway Call Rate	Alert on abnormal call rate changes
Mapping Packet Loss Rate	Alert on high packet loss percentage

Configure alarms through Alarm Management > Alarm Settings > Mapping Alarm in the VOS3000 interface. Understanding these alerts is crucial for maintaining service quality, as discussed in our article about VOS3000 extended firewall and security.

🎯 Gateway Sorting with ASR ACD – VOS3000 ASR ACD Analysis

VOS3000 uses a sophisticated gateway sorting algorithm that incorporates ASR and ACD metrics. Understanding this sorting process is essential for optimizing your routing configuration.

📋 Gateway Sorting Priority Order:

1. Routing first/second routing strategy enabled for mapping gateway or calling phone
2. Longest prefix matching principle
3. Prefix priority of routing gateway
4. Routing gateway priority (smaller = higher)
5. Line Usage sorting
6. ASR-based sorting (if enabled)
7. Current Day Total Call sorting
8. Gateway ID sorting

When SS_GATEWAYASRROUTESORTCONFIG is set to “Before Current Day Total Call”, routes are sorted by ASR value. Gateways with disabled real-time ASR calculation are prioritized over those with it enabled. Learn more about gateway configuration in our SIP trunking configuration guide.

❓ FAQ – VOS3000 ASR ACD Analysis

Q1: What is a good ASR value for VoIP routes?

A: A good ASR value typically ranges from 40-60% for retail traffic and 30-50% for wholesale traffic. Values below 20% usually indicate route quality issues that need investigation.

Q2: How often should ASR ACD reports be generated?

A: For high-traffic platforms, daily reports are recommended. For smaller installations, weekly reports may suffice. Enable automatic report generation in system parameters.

Q3: Can ASR ACD analysis help identify fraud?

A: Yes, unusually high ASR combined with low ACD can indicate artificial traffic or SIM box detection. Monitor for patterns that deviate from normal traffic behavior.

Q4: What’s the difference between ASR and ACD?

A: ASR measures call success rate (answered calls / total attempts), while ACD measures average duration of connected calls. Both metrics together provide comprehensive quality insights.

Q5: How do I enable real-time ASR calculation?

A: Set SS_GATEWAY_ASR_CALCULATE to “On” in Softswitch Management > Additional Settings > System Parameters, then enable “Calculate routing quality in real time” on each gateway.
