SIP trace and capture analysis
Turn debugs, logs, and packet captures into call ladders. Score media quality and export audio from captured calls.
CollabPlane Workbench
SIP and call troubleshooting
Find out why
the call failed.
Workbench is a set of troubleshooting tools for voice engineers. Load a SIP trace, a packet capture, or a call manager log, or pull one from the device, and read the call as a ladder with the differences marked.
Workbench is delivered as a hosted service. There is nothing to install except the on-site collector, where one is needed. Workbench includes a 14-day trial; ask sales to start one.
Call comparison
| Message | Working call | Failed call |
|---|---|---|
| INVITE | Sent | Sent |
| Codecs offered | G.711, G.729 | G.729 differs |
| 100 Trying | Received | Received |
| Final response | 200 OK | 488 Not Acceptable Here differs |
What Workbench does
Call comparison
Put a working call beside a failed one and see which messages and fields differ.
One call across devices
Search by a call identifier or a number and follow each leg from the SBC to the call manager to the cloud.
Capture from the device
Start a time-boxed capture on Cisco, AudioCodes, and Ribbon devices through an on-site collector.
Rule builders
Build SIP profiles and voice translation rules, test them against a real message, and push them with a saved rollback.
Cloud call records
Retrieve Microsoft Teams, Webex Calling, and Zoom Phone call records to set beside your own capture.
Compare calls, message by message

Everything in Workbench
29 tools. One sign-in.
Each tool does one job. Results from one feed the others, so a call found in a capture can be opened in a comparison or saved to a case.
Analyze
- SIP Trace Analyzer
- Turns CUBE debugs, syslog and Wireshark text exports into call ladders and flags failure signatures.
- Call Comparison
- Two calls side by side, message by message, with the differing headers and SDP fields highlighted.
- PCAP Analyzer
- Reads SIP and RTP from a packet capture, scores media quality, detects DTMF and exports audio.
- PCAP Comparison
- Correlates one call across captures taken at different points in the path.
- CUCM Trace Analyzer
- Rebuilds the call flow from Cisco Unified CM call logs across cluster nodes.
- End-to-End Troubleshooting
- Joins call manager logs, gateway debugs and cloud call records into one call.
- Dial-Peer Lens
- Shows which inbound and outbound dial-peers a CUBE matched for each call.
- CCAPI Flow
- A per-call timeline from the gateway call-control debug: legs, codec negotiation, connect and disconnect.
- WebRTC Stats
- Reads a browser getStats dump from a Teams, Webex or Zoom web client.
- Call Spine
- Search by any call identifier or number and see every leg recorded for that call.
- Investigations
- Save an analysis as a case with its conclusion and a report to hand to a vendor or customer.
- Voice Reference Tables
- Disconnect cause codes and codec, tone and fax values in plain English.
Capture and record
- Cisco VoIP Trace
- Searches the trace buffer a CUBE keeps, whether or not anyone was debugging.
- AudioCodes Capture
- Runs a filtered packet capture on an AudioCodes SBC and analyzes the result.
- Ribbon SBC Core
- Reads signaling ports and counters and runs an audited call trace on a Ribbon SBC Core.
- SIPREC Recorder
- Records a call as the SBC hears it, with each audio stream labelled by participant.
- Recordings
- Records a device for a fixed window that always ends by itself.
- Call Test
- Places a real test call through a trunk, gateway or SBC from inside your network.
- Collector Agents
- An on-site agent that reaches devices on private networks and connects outbound only.
- Devices
- Your saved devices, private to your account, with encrypted credentials.
Build and test
- SIP Profile Builder
- Builds CUBE SIP profile rules and gives you paste-ready configuration.
- SIP Profile Tester
- Runs a SIP profile against a real message and shows the before and after.
- Voice Translation Rule Builder
- Answers plain questions and produces a correct Cisco voice translation rule.
- Config Audit
- Every configuration change pushed from Workbench: who, what, where, when, with a backup and a rollback.
Cloud call records
- Microsoft Teams
- Pulls Direct Routing and PSTN call records and lines them up with your SBC legs.
- Webex Calling
- Retrieves detailed call history for a date range or number.
- Zoom Phone
- Retrieves call history and quality data for a date range or number.
Integrations
- Recommendations
- Points to the element and layer most likely at fault and suggests next steps.
- ServiceNow
- Pulls a trace attached to an incident, analyzes it, and posts the findings back.

Is Workbench right for you?
Where did these calls behave differently?
For individuals and teams investigating UC faults and reviewing configuration.
- Start with
- Supported SIP traces, packet captures, CUCM logs, and the configuration context for the affected call.
- Work toward
- Call comparisons, signaling and media observations, and findings to guide the next scoped test.
- Compare successful and failed calls side by side.
- Review signaling and media evidence from supported inputs.
- Use configuration tools to investigate a specific engineering question.
An example
Two calls. One useful difference.
Compare a successful call with a failed one. Follow the signaling, correlate available media evidence, and capture the configuration context needed to test a specific explanation.
- 1Scope the affected call
- 2Collect the relevant evidence
- 3Compare signaling and media
- 4Review the proposed change
