Operate

Start with the symptom you are investigating, or prepare an installation using the deployment guides.

Start with a task

• Plan capacity and maintenance — Configure fleet limits, API protection and deliberate drain/refresh operations

• Configure and rotate database credentials — Separate migration, runtime and backup identities; verify refreshed connections

• Verify security event export and retention — Trace audit evidence to its destination and check each retention policy

• Configure and verify email delivery — Select the actual sender, check SMTP/SES and separate a queued message from recipient delivery

• Interpret a call summary — Read CDR status, identifiers, recording indicators and available usage without confusing them with billing or business success

• Diagnose background jobs and schedules — Separate queue state, retries, scheduling and the actual result

• Locate a service and its dependencies — Understand roles, optional services and request paths

• Check service health and intervention scope — Diagnose the affected layer before restarting

• Verify release identity and compatibility — Check the actual component set and recovery boundary

• Choose and verify configuration recovery — Understand snapshot scope, replacement, sensitive fields and activation

• Refresh running services — Choose targets and drain/restart behavior; inspect per-target results before resuming normal traffic

• Reconstruct an audited change — Identify who acted, what changed and which stage actually completed

• Deploy, verify and update Delphi — Configuration, activation, health and recovery for service-host deployments

• Deploy and verify system audio — Configure isolated storage, preparation checks and reliable deletion

• Understand logs and diagnostics — Choose audit, service, SIP or call evidence

• Telemetry, SigNoz and alerts — How each host's collector feeds SigNoz, how to open its views, and which alerts and dashboards Delphi provides

• SIP signaling and trunk log reference — Find and read SIP edge records, SIP captures, call rejects and trunk health records

• Diagnose a failed or misrouted call — Trace routing and termination back to configuration

• Find missing recordings or transcripts — Check selection, frequency, processing, storage and playback

Prepare an installation

• Deployment prerequisites — Hosts, networks, DNS names and external services an installation needs
• Provision instances and bootstrap — Create the service hosts and run the first setup
• Environment variables — Every variable by service, with defaults and owners
• Operate the telephony edge — Run, drain and restart the SIP edge and media relay
• Operate the voice services — Run the call runtime, its media server and the audio processors
