PingPlotter
SMBNetwork diagnostic tool that traces packet loss and latency affecting real-time VoIP call quality.
Interactive traceroute graphing with historical hop charts to correlate path instability to voice incidents.
PingPlotter is commonly used to trace the path to a SIP trunk, media gateway, or SBC endpoint and to visualize when jitter and packet loss emerge along specific hops. The tool records probe history so teams can compare incidents across time windows and isolate whether the degradation is local, upstream, or destination-side. It pairs naturally with voice troubleshooting because the workflow starts with the network path and then moves up to SIP messaging and media behavior.
A key tradeoff is that PingPlotter is strongest for IP path observability and less specialized for SIP-specific validation such as header-level parsing, codec negotiation checks, or RTP stream scoring. It fits best when teams need rapid correlation during outage windows or change events, like carrier reroutes, NAT rule updates, or firewall policy shifts that affect UDP media paths.
- +Per-hop timeline helps pinpoint where jitter and loss originate
- +Long-running probe history supports incident comparison
- +Resource-light monitoring fits ongoing VoIP operations
- +Repeatable monitoring workflows support multi-site troubleshooting

enterpriseUnified communications monitoring and diagnostics platform covering VoIP quality, SIP trunking, and UC platforms.
Workflow-based test recipes that generate comparable call-quality and signaling results across many endpoints.
IR Prognosis fits teams that need repeatable call testing across SIP interconnect paths and require consistent reporting across many scenarios. The core workflow treats each scenario as a test recipe that triggers calls, validates SIP signaling behavior, and measures media quality characteristics. The product works best when test cases are treated as assets managed by the operations team rather than ad hoc by individual troubleshooters.
A tradeoff appears in governance and change control, because scenario libraries and endpoint inventories must be kept current for the results to remain meaningful. IR Prognosis is a strong fit for regression testing after SIP trunk changes, codec policy updates, or carrier routing adjustments, where teams need comparable output run-to-run. It is less efficient when the goal is only brief, interactive troubleshooting without scenario reuse.
