❓ Frequently Asked Questions

How do I check ASR for a specific gateway?

Navigate to CDR Analysis > Routing gateway Analysis > Routing gateway performance. Select the gateway and date range. The ASR (Answer Seizure Ratio) will be displayed showing the percentage of calls that were successfully connected versus total attempts.

What is the difference between call duration and conversation duration?

Call duration is the total time from call setup to teardown, including ringing time. Conversation duration is the actual talk time from when the call was answered until hangup. The difference represents ringing and setup time.

How can I find why calls are failing to a specific destination?

Use the Fail Analysis feature in CDR Analysis. Navigate to Routing gateway > Fail analysis, select the gateway handling that destination, and review the termination reasons distribution. This shows why calls are not completing.

What is a good ASR target for VoIP routes?

ASR targets vary by route type. Wholesale termination routes typically target 40-60% ASR. Premium routes may achieve 70%+. Routes below 30% ASR often indicate quality issues that need investigation.

How do I export CDR data for external analysis?

In the CDR query screen, apply your desired filters, then right-click and select Export. The data will be saved in CSV/Excel format that can be imported into external analytics tools for deeper analysis.

VOS3000 Monitoring FAQ – Reports, Alarms & Administration Explained

Author: Rana Khan

Welcome to the VOS3000 monitoring FAQ guide. This comprehensive documentation covers all essential questions about VOS3000 monitoring configuration, report generation, alarm setup, and system administration based on official documentation.

VOS3000 is a professional VoIP softswitch system that requires comprehensive monitoring capabilities for operational visibility, service quality assurance, and proactive issue identification.

Server Monitoring – VOS3000 Monitoring

1. Server monitor

Server monitoring in VOS3000 provides real-time visibility into system health, resource utilization, and performance metrics. The server monitor captures key performance indicators including CPU usage, memory consumption, disk I/O, network activity, and call processing statistics.

Effective server monitoring tracks multiple metric categories that collectively provide complete visibility into system health and performance. Resource utilization metrics include CPU, memory, disk, and network for capacity and bottleneck identification. Call processing metrics include concurrent calls, success rates, and setup latency.

Reports & Alarms

2. How to set automatic e-mail report and alarm

Configuring automatic email reports and alarms ensures stakeholders receive regular updates on system status without manual intervention. Email reports can be scheduled for daily, weekly, or monthly delivery with content customized for different audiences.

To set up automatic email reports and alarms, navigate to the notification configuration section and specify report schedules, recipient email addresses, and content parameters. Configure alarm triggers for key metrics including CPU utilization thresholds, call success rate minimums, and security event detections.

3. How to generate report manually/automatically

VOS3000 provides flexible report generation tools that enable customization of time periods, data filters, and output formats. Manual report generation supports ad-hoc analysis, investigation of specific issues, and generation of reports not covered by automatic scheduling.

Automatic report generation can be configured for recurring schedules with predefined content and recipients. Manual report generation allows customization of parameters including date range, data filters, and output format. Export options include various formats for offline analysis or distribution.

4. How to analyze routing

Routing analysis enables continuous optimization of call routing based on performance data and quality metrics. VOS3000 routing analysis tools provide visibility into routing success rates, gateway performance, and destination-level quality metrics.

Use routing analysis tools to examine per-gateway success rates, per-destination performance, and failover effectiveness. Identify underperforming gateways and destinations, analyze routing patterns for optimization opportunities, and measure impact on call completion rates and quality metrics.

CDR Management

5. Cdr queue

CDR queue management ensures that call detail records are processed completely and accurately even during high-volume traffic periods. The CDR queue buffers incoming call records during processing peaks and manages systematic record handling to prevent data loss.

CDR queue monitoring provides visibility into the volume of records awaiting processing and helps identify potential bottlenecks. A growing queue depth indicates that CDR processing cannot keep pace with call volume, which could result in delayed billing or potential data loss.
