Definitions

Bad-call rate — share of calls with a quality problem (audio / video / connection).
P2P vs Meet — P2P = 1-to-1 call; Meet = group call.
Not-ring — the callee did not get a proper ring (call-setup stage).
  • delay-ring — rang but late (push / signaling latency).
  • silence / never-ring — never rang at all.

 

OTP — one-time verification-code SMS.
Auto-fill — code auto-entered on Android (SMS Retriever); raises OTP entry success rate.
Routing optimization — send each country OTP via its cheapest qualified vendor.
eBPF — kernel-level network optimization → less CPU per node → fewer machines.
pp — percentage points.

Call Quality
2 / 3
chart
Ring path: silence/never-ring keeps falling to a new low 13.3% (structural win). The June delay-ring spike was a push/signaling bug — recovered by Aug.
chart
P2P audio bad −22% (4.96→3.85%) · total bad-call −7% (28.6→26.6%, Jun–Jul→Aug); year-earlier −15.5% Dec→May hit the goal.
User rating 4-5★ →85.5% (+4.4pp since Dec, 81.1→85.5%), avg 4.23→4.37 — kept rising through the SDK-test window.
bad-call = cnt_any_bad_call / total_calls · ring-failure = call-setup bad / paired calls · Grafana/CelerData.
Cost savings — OTP & eBPF
3 / 3
chart
OTP 286K SMS/day. Route each country to its cheapest qualified vendor → save ~$29K/mo (+WELINK ~$31K). Android auto-fill also cuts wasted resends.
chart
eBPF optimization lets us decommission servers → net ~$23.6K/mo (~$284K/yr, ~50% of infra budget). Quality-neutral on AE→AE P2P (9.27 vs 9.02%).

Platform & AI

Lucy / Lighthouse insight agent — AI analyzes production issues & surfaces alerts. · OpenPlatform — unified docs, MiniVerse (AI codegen)+CLI, plugin system, grayscale cohort, closed-loop feedback.
OTP: otp_vendor_comparison (volume × vendor price). eBPF: infra billing (decommission − added). Fraud-blocking savings pending T+1 dashboard.
