Enable Call Timeline for CDR

Timeline-based CDR displays call details in a structured and chronological order. All events from call start to call end are recorded, providing clear visibility into call activity and enabling faster troubleshooting. This topic describes how to enable call timeline for CDR.

Requirements

The firmware version of Yeastar P-Series Software Edition is 83.21.0.117 or later.

Procedure

  1. Log in to PBX web portal, go to Reports and Recordings > CDR.
  2. In the CDR (Advanced) tab, turn on the switch of Timeline.

  3. In the pop-up window, confirm the operation.

    1. If you are prompted to adjust the CDR storage limit, select a value from the drop-down list of Modify Max Number of CDR.
      Important: CDR storage limit is determined by the server hosting the PBX. Exceeding the limit could result in new CDRs not being recorded and may impact system stability.

      Please adjust the limit according to the server specifications listed below:

      • Extensions ＜ 1000: Maximum 500,000 CDRs
      • Extensions ≥ 1000 (IO < 150MB/S): Maximum 2,000,000 CDRs
      • Extensions ≥ 1000 (IO > 150MB/S): 5,000,000 CDRs
    2. Click OK.

Result

  • Call timeline feature is enabled for CDR; New CDRs from new calls will include timeline data.
    Note: Legacy CDRs do NOT include timeline data.

    You can access new CDRs from PBX web portal and view the key metrics as needed.

  • If you have adjusted the CDR storage limit, the setting will automatically synchronize to the CDR auto cleanup rule (Path: System > Storage > Auto Cleanup > CDR Auto Cleanup > Max Number of CDR) and take effect after a system reboot or at 00:00.
    Note:
    • If there are legacy CDRs, the system will take the following actions:
      1. When the total number of CDRs reaches the limit, the system purges legacy CDRs at a 1:5 ratio (5 legacy CDRs purged for every 1 new CDR generated).
      2. After all legacy CDRs are cleared, the system sends a event notification Legacy CDRs Have Been Fully Cleaned Up to keep you posted.
    • We recommend that you back up legacy CDR data in advance to prevent potential data loss during the cleanup process.
