A 30-minute monthly audit for VoIP documentation
A monthly documentation audit should look for operational drift, not reread every diagram. Thirty focused minutes can catch the changes most likely to slow an incident or make a recovery procedure fail.
Minutes 0–5: contacts and authority
Confirm the carrier escalation path, account identifier, authorised contacts and secure method for sharing captures. Remove departed staff and verify that somebody on the current roster can open a fault.
Minutes 5–12: numbers and routes
Review ports completed that month, new DIDs, emergency-location changes, main-number destinations and temporary diversions. Sample one number from each important route instead of attempting a full inventory every month.
Minutes 12–18: versions and certificates
| Item | Record |
|---|---|
| PBX and SBC | Running version, approved version and next maintenance date |
| Phone fleet | Approved firmware by model and known exceptions |
| Certificates | Expiry, owner and renewal method |
| Backups | Last successful job and last restore test |
Minutes 18–25: recovery reality
Choose one recovery instruction and confirm it still matches the interface, credentials process and equipment. Rotate the check between carrier failover, PBX restore, SBC replacement, phone reprovisioning and after-hours diversion.
Minutes 25–30: close the drift
Assign an owner and date to each discrepancy. A list titled “documentation needs updating” is not a control. Update small factual errors immediately; create tracked work for changes that require testing or approval.
The audit is complete when another technician could act from the corrected record. Its purpose is not to make documentation look tidy.
