❓ 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.
