SIP trace packet analyser

Paste a SIP message — request, response, or a raw trace entry — and get a line-by-line breakdown with RFC references. Strips common trace prefixes (Cisco CUCM, Asterisk, FreeSWITCH, Wireshark export). Parses URIs, Via chains, Digest auth, and SDP bodies. The aim is to give a UC engineer enough decoded context to do their own heavy lifting from there.

⚠ Disclaimer This tool is provided as-is, for educational and planning purposes only. All parsing runs entirely in your browser — pasted SIP messages never leave the page. That said, SIP traces often contain sensitive data (PII in From/To, dialled numbers, auth credentials, internal IPs, signalling secrets) — check your org's data-handling policy before pasting production traces into any browser tool. The Tech Space makes no warranty and accepts no liability. Full disclaimer →
