Operational visibility

Capture the call, the route, and the logs.

TunaIO is designed for distributed SIP networks where a single customer test call may touch a provider, an edge SBC, an access SBC, a PBX SBC, and an application server.

Remote capture orchestration

Send one capture request to many agents and receive matching SIP events in one web session.

Sngrep-style ladder

Review live call summaries first, then expand the specific call to inspect every message and SIP payload.

Safe capture rules

Empty captures are rejected. Sessions have default expirations and configurable limits to protect busy production nodes.

Log correlation

Match Kamailio, FreeSWITCH, and Asterisk log lines by call identifiers, route metadata, numbers, and text.

RTP streaming option

Capture media when you need to inspect one-way audio, gaps, codec mismatches, or failover behavior.

Session sharing

Create read-only links for a specific troubleshooting session without giving full control-plane access.

Signals that matter.

TunaIO is not just a packet viewer. It is built around the operational questions VoIP teams ask under pressure.

Which SBC did the provider hit?
Which route did the application select?
Did the call fail before or after PBX handoff?
Did Asterisk or FreeSWITCH answer, reject, or timeout?
Was the RTP stream still present during failover?
