2. The calculator (cdr-quality-summary.js of 18 Oct 2026), shareable summary:
CDR quality summary (srvscripts.com/tools/asr-and-acd-calculator/)
Source: FreePBX / Asterisk CDR database export, 20 rows, 17 calls (18 legs grouped by call id), 2 row(s) rejected as malformed
Calls 17 | answered 10 | busy 2 | no answer 2 | failed 3
ASR 58.8% | NER 82.4% | ACD 1:01 | billed 10 min | short (<6 s) 10% | 0 s answered 10% | avg time to answer 7.2 s

INFO Only 17 calls: percentages move a lot with a few calls; use a day or more of traffic before drawing conclusions.
WARN 17.6% of calls FAILED (congestion, unavailable, rejected). That is usually the trunk, the carrier, a route or a channel limit, not the people you call.
WARN 10% of answered calls lasted 0 seconds. Check for calls answered and dropped at once (fax, robocall filters, answer supervision on the trunk).

Per trunk:
  PJSIP/carrier-a: 8 calls, ASR 62.5%, NER 87.5%, ACD 0:48, failed 1
  PJSIP/carrier-b: 8 calls, ASR 50%, NER 75%, ACD 1:25, failed 2
  PJSIP/1003: 1 calls, ASR 100%, NER 100%, ACD 0:35, failed 0
Per hour:

  11:00: 8 calls, ASR 50%, NER 75%, ACD 1:19
Rejected rows: row 12 (duration "abc" is not a plausible number of seconds); row 13 (only 3 columns)
