Make sense of VoIP captures

Upload a network capture (.pcap) of a phone call — Pcap-Diagnose analyzes the SIP and RTP flow automatically and explains, in plain language, what's most likely wrong.

First analysis per email address is free. Then 10 analyses for €9 — no subscription. (The app's UI is currently German.)

What the diagnosis gives you

A capture turns into an assessment you can act on right away.

Automatic diagnosis

SIP message flow, response times, error codes and RTP are analyzed and summarized into a clear assessment.

Privacy-minded

Phone numbers and public IP addresses are masked on the server before any text extract goes to the AI service. The file itself is deleted after the analysis.

Built for support

Category (A/B-side/network), a short summary and a copy-ready customer note — made for quick triage in 2nd-level support.

How it works

From capture to assessment in three steps.

1

Upload the capture

Upload the pcap/SIP capture of the affected call and pick the symptom.

2

Mask & analyze

The server masks numbers and IPs and analyzes the flow — without passing your file on.

3

Get the assessment

Category, summary and details — ready to paste into the ticket.
