Application and call-flow logging

What TelSys, TelPro, and RTPEngine log during a call, how log levels are used, and how to correlate application logs with SIP signaling.

Audit logging

What Delphi records as audit and security events — the per-event fields required by BSR 4.1.1/4.1.2 (time, type, origin IP, user ID), the actor-context block, and which platform actions emit which event.

Call Detail Records (CDR)

One summary log record per call — timing, bot context, provider identifiers, latency, error/fallback, and correlation IDs — queryable in SigNoz and persisted to AppLog.

Job history

Read-only history of background jobs — status, attempts, results, and errors.

Log and telemetry obfuscation

How Delphi scrubs PII — DTMF digits, phone numbers, transcripts, and secrets — across three layers: the in-process logger, the DTMF-aware logDTMF helper, and the OTel collector transform processors.

Monitoring in SigNoz

How Delphi services send logs, traces, metrics, health signals, and call debugging data through OTel collectors into SigNoz.

OTel collector configuration

How the per-host OpenTelemetry collector is configured on a Delphi deployment — the file you edit, the receivers, processors and pipelines it runs, the environment variables substituted into it, and how to change the PII obfuscation rules.

Service logs

What each Delphi service logs, where the logs land (SigNoz via OTLP and stdout filelog), and the full TelWeb and TelPhi log inventories — server-side structured logs, call/telephony events, CDR, AI/DB spans, audit/auth events, route-handler logs, and client-side console output.

SigNoz service operations

SigNoz observability backend on static private IP 10.0.1.10 — Foundry deploy, version upgrades, legacy migration, alert sync, and troubleshooting.

SIP signaling reference

What Kamailio and TelSys log for SIP — capture points, methods (OPTIONS, CANCEL, PRACK), response codes (481, 487), and how records reach the Debug SIP ladder.

SIP trunk health monitoring

How the configured Delphi inbound SIP trunk monitor works, what available/degraded/unavailable mean, how to query the /health/sip-trunks endpoint, and how trunk-down alarming works.

SIP trunk log reference

Catalog of SIP trunk health logs emitted by TelPhi and TelAPI — when each fires, what it means, and which payload fields appear.

Trace debug search

How super-admins search retained SigNoz telemetry by trace ID, call ID, or SIP header value from the TelWeb Trace Debug view — friendly header mode and raw ClickHouse SQL mode.
