fixa

Ship your voice bot with confidence by rehearsing every call before it meets a customer. fixa gives you a repeatable way to exercise and verify AI calling experiences from dial tone to goodbye. Connect your voice app (SIP, PSTN, or WebRTC), point Fixa at your staging or prod-like environment, and build realistic call scripts: greetings, intents, barge‑ins, DTMF, silence, background noise, and edge cases. Choose the mix of carriers, regions, and devices to test, set pass/fail thresholds for timing and quality, and schedule runs on commit, nightly, or before a release. Your team sees the same source of truth on what works, what’s slow, and what breaks.\n\nWhen a suite runs, Fixa spins up synthetic callers that actually dial your endpoints and talk to your agent. It records audio, transcripts, and a detailed timeline of every event: connect time, first byte of TTS, ASR partials, handoff latency, interruption handling, and disconnect reason. You’ll get a waterfall view that exposes slow turns and stuck states, plus comparisons across vendors, models, and configurations. Trend metrics over time to spot regressions—like a new prompt that adds 600 ms to the first response or an update that mishandles overlapping speech. Outliers are flagged automatically with context so you know if issues are network, carrier, model, or app logic.\n\nIf something goes wrong, open the call trace to debug fast. Scrub through the waveform while reading aligned transcripts and intent decisions. Inspect per-turn timings, token rates, silence detection triggers, and error codes in one place. Replay the exact scenario with a click, tweak variables (noise level, speaking rate, accent), and run again to confirm a fix. Convert a failing trace into a permanent regression test, attach it to a ticket, and notify your channel via Slack or webhooks. Gate deployments with Fixa’s API so a PR can only merge when critical voice checks pass. Export logs, JSON, and audio for deeper analysis or compliance, and keep sensitive content safe with built‑in redaction.\n\nUse Fixa to iterate, not just validate. Trial a new ASR/TTS stack side‑by‑side, tune prompts for faster first response, and prove barge‑in works across accents. Run load and soak tests to uncover memory leaks or rate‑limit edges before traffic peaks. Confirm routing and fallback behavior across carriers and geographies. Track KPIs like call completion, average turn latency, and drop rate against SLOs; alert the on‑call when thresholds drift. With consistent, automated call practice, your voice agent keeps improving—and customers feel the difference on day one and every day after.
