From SIP Pings to Autonomous AI Conversations
The Sipfront Core Engine is a high performance orchestration layer designed to simulate real-world user behavior. We bridge the gap between legacy PSTN signaling and modern WebRTC/AI-native communication with millisecond precision.
Bridging PSTN, Voice AI, and WebRTC
Validate the hand-off, not just the hop. Our engine allows you to map complex, cross-protocol journeys: Start a call via a global PSTN gateway, navigate a Voice AI IVR, and verify the transfer to a WebRTC-based agent interface — all while capturing full packet level forensics.
- Protocol Bridging: Seamlessly orchestrate flows across SIP, PSTN, and WebRTC (SDP/ICE) in a single unified test case.
- Stateful Call Logic: Perform complex actions like DTMF, T.38 fax, hold/retrieve, and both blind and attended transfers.
- Total Path Visibility: Monitor every signaling event and media packet from the customer’s ear to the agent’s browser.

Carrier-Grade Load & Stress Testing
Find the breaking point of your SBCs, media relays, and transcoding engines before your customers do. Simulate massive concurrency without the overhead of manual coordination.
- High-Volume Signaling: Validate proxy and registrar capacity with hundreds of Calls Per Second (CPS).
- Distributed RTP Stress: Generate symmetric or asymmetric media load from global cloud nodes to stress-test your TURN/STUN and media-relay infrastructure.
- Performance Profiling: Identify the exact point where jitter, packet loss, or latency impacts Mean Opinion Score (MOS).

Regression & CI/CD for Voice
Treat your voice infrastructure like code. Automate the validation of every software update, firewall change, or routing adjustment with fully reproducible technical baselines.
- DevOps Ready: Trigger complex test books via REST API or our MCP server directly from GitHub Actions, GitLab, or Jenkins.
- Performance Baselines: Compare every run against a known-good gold standard to detect sub-perceptual regressions.
- Automated Maintenance Audits: Replace hours of manual 3 AM testing with a single-click, full-stack verification run.

24/7 Global Probing & Alerting
Monitor reachability and media quality from the perspective of your global users. Sipfront provides an outside-in view of your production environment that internal metrics often miss.
- Global Reach: Persistent probing from major carrier hubs to verify international peering and transit quality.
- Threshold-Based Alerting: Push millisecond-accurate failure notifications to Slack, MS Teams, or PagerDuty.
- SLA Reporting: Generate audit-ready reports on uptime, signaling success rates, and media path integrity.

Built by the Architects of Modern VoIP
We don’t just use these tools; we helped define the standards. With deep roots in the Kamailio management board and having founded the rtpengine project over 15 years ago, Sipfront is built on decades of core telco expertise. We understand the signaling debt of Asterisk and FreeSwitch because we’ve been there since the beginning. We built the foundations of the modern VoIP world — and we’ve built the ultimate engine to prove it works.
