The Voice Call Logs page is your audit trail - every call your account placed or received, with timing, audio quality, hangup cause, and a full SIP timeline.

The Call Logs page

Voice Call Logs page showing KPI tiles (Voice API Spend, Total Calls, Answered, Answer Rate, Avg Duration) at the top, a paginated list of call records on the left with MOS scores and durations, and a Call Details panel on the right with Call Timeline (Initiated, Ring Start, Not answered, Ended), From, To, Direction, Type, Call ID, Duration, and Total Cost

Voice Applications - Call Logs

The page is laid out top‑to‑bottom in three bands.

​
1. KPI tiles

Trend pills compare against the previous window - see Dashboard for how the comparison works.

​
2. Call list

The left column lists every call in the date range. Each row shows:
  • From → To numbers (with direction icon).
  • Date and timestamps (HH:MM:SS - HH:MM:SS) plus duration.
  • Hangup cause badge - Caller hung up, Recipient busy, Not answered, etc.
  • MOS score - Mean Opinion Score (1.0–5.0). 4.0+ is good, 3.5–4.0 acceptable, below 3.5 indicates audible quality issues.
Click any row to load its details on the right.

​
3. Call Details panel

The right side has four tabs:
  • Call Details - Call Timeline (Initiated → Ring Start → Answered/Not answered → Ended), From/To with country flag, Direction, Type (Voice Application, SIP, API), Call ID (the canonical handle to quote in support tickets), Call Duration, and Total Cost.
  • Call Stats - packet loss, jitter, codec, network conditions.
  • Call Quality - MOS breakdown by leg (inbound vs outbound).
  • More - raw SIP headers, full hangup cause code, redirect history.
Three links above the tabs:
  • Summary / View detailed logs toggle - flip between the timeline view and a full SIP message log.
  • No Recording badge - turns into a ▶ Play button if the call was recorded (Recordings).

​
Search and filter

The two controls above the call list:
  • Search by phone number, call ID or DID - substring match across from, to, the Call ID UUID, and the DID it routed through.
  • Filters - opens the side panel for structured filtering.
Filter Call Logs modal with fields for Direction (All, Inbound, Outbound segmented control), From Number, To Number, Min Duration in seconds, Max Duration in seconds, and Hangup Cause dropdown set to Any, with Clear All and Apply buttons at the bottom

Filter Call Logs side panel

Apply persists the filter; Clear All resets to defaults.

​
Export to CSV

The Export CSV button (top‑right of the page) downloads every call in the current filter + date range as a CSV file. Columns include all the fields visible in the details panel plus the Call ID - ready to drop into a spreadsheet or load into BigQuery for deeper analysis.
Combine Max Duration = 5 with Hangup Cause = Recipient busy to surface campaigns hammering numbers that keep declining - usually a sign to drop those numbers from your dialler.

​
Tips

  • Always quote the Call ID when filing a support ticket. It’s the canonical handle and lets Vobiz support trace the call across every internal system.
  • MOS < 3.5 consistently usually means a network problem on the caller’s side or codec mismatch - open Call Stats to confirm.
  • Page 1 of N at the bottom - pagination is server‑side. Filters apply before pagination, so deep paging stays fast.
