SIP trace capture

Trace SIP where external capture cannot.

When TLS makes packet capture blind, Cocktel can collect signaling inside the client and keep the result tied to the exact call leg that created it.

SIP trace capture

Per-call traces stay attached to the call.

Cocktel separates per-call signaling artifacts from the shared app log. Capture mode, auth-redaction state, and call metadata are stored with the manifest so exports remain understandable later.

Per-call scope

Capture files are keyed by call UUID, not by global logging sessions.

Header or full mode

Choose headers only, or full SIP plus SDP when media negotiation matters.

Redacted or raw auth

Auth redaction is a user preference with per-call override, not a hidden hardcoded behavior.

Journal retrieval

Copy, export, and reveal captures from the Call Journal without mixing conferences or unrelated calls.

What the diagnostic tools cover

  • Registration health and failure reasons.
  • TLS transport events.
  • Codec, SRTP, RTP endpoints, packet loss, jitter, and RTT summaries.
  • SIP capture manifests with effective capture and redaction modes.
