Telco

The Telco tab is the signaling-focused cockpit for telecom captures. It is designed for cases where SIP, IMS, Diameter, NGAP, GTP, SCCP, TCAP, or related telecom protocols dominate the investigation.

PacketSafari also puts a lot of its anonymization effort into this same protocol family. The current anoncap profile and private regression coverage are heavily biased toward telecom signaling and subscriber-identity scenarios, so telco-heavy captures are one of the places where deep anonymization support is strongest.

What it highlights

• Protocol error digests with severity and action hints
• SIP response and request code summaries
• Failed dialogs and calls with issues
• Grouped signaling sequences and ladder-style inspection
• Packet filters, frames, and evidence summaries attached to supported findings

Common workflow

1. Open Telco after PacketSafari detects telecom signaling.
2. Review the top protocol errors and failed dialogs.
3. Separate correlated call issues, indexed SIP findings, and SIP/dialog heuristics in the call detail.
4. Drill into the grouped dialog or ladder view for the most important sequence.
5. Use the packet action to inspect the supporting filter or frames, or launch Agent from the relevant telco evidence.

Notes

• The tab is optimized for signaling correlation, not just packet listing.
• A grouped dialog state or heuristic is a lead, not a verified service-impact conclusion. Confirm it against response behavior, packet evidence, capture viewpoint, and the expected call flow.
• The same telecom protocol families that drive this tab also receive some of the deepest anoncap regression coverage.
• Hosted preview tiers can show lower-signal hints while deeper findings remain gated.
• Use VoIP for media-focused RTP troubleshooting and Telco for signaling-heavy analysis. When SIP context is available, the VoIP view links back to the Telco calls view.
