Call Analyser
Upload a trace, isolate each interaction and follow the complete signalling path in a clear, inspectable view.
SIP diagnostics, clearly
See the call. Find the fault.
A focused workspace for SIP engineers to capture real traffic, inspect every exchange, simulate call flows and surface likely problems.
- Private trace library
- Browser-only simulation
- Evidence-led AI analysis

The toolkit
One workspace. Every angle.
Move from capture to explanation without stitching together a stack of disconnected tools.
AI Problem Finder
Turn a complete call into a grounded problem summary, with the evidence engineers need to verify the result.
SIPulator
Build and inspect realistic SIP scenarios locally in the browser—then export them into the same analysis workflow.
WSSPhone
Place and receive test calls over secure WebSocket, save profiles and capture the signalling when something goes wrong.

Keep the evidence in view.
SIPnostic keeps every conclusion close to the traffic that supports it.
- 01CaptureUpload a trace or record a test call.
- 02InspectFollow the exchange and open any message.
- 03ResolveConfirm the likely cause against the packet evidence.
Private by design
Your traces stay yours.
Diagnostics often contain sensitive network and call data. SIPnostic is designed around deliberate handling, not accidental retention.
Encrypted and private
Uploaded trace files and their stored analysis belong to the authenticated user.
Local simulation
Generated scenarios run in the browser and never contact the host entered in the form.
Request-only
Number metadata is resolved from bundled data, and lookup requests are not retained.
Permission-led
AI access and optional audio inspection are separately controlled at account level.
Built for the people on the call
Less guesswork. More signal.
Bring capture, simulation and diagnosis into one focused SIP workflow.
