Sherlock Calls — Your AI Call Detective for Voice Operations vs Twilio

Twilio offers developers a powerful API for phone services to make and receive phone calls, and send and receive text messages. Their product allows programmers to more easily integrate various communication methods into their software and programs.

Sherlock Calls is a Slack-native call detective for voice operations teams. When a call fails, evidence is scattered across Twilio call events, ElevenLabs audio and TTS behaviour, webhooks, and CRM records. Sherlock connects to a team's stack via OAuth, correlates provider data, and posts a structured incident case file in Slack: a timestamped cross-provider timeline, root cause hypothesis with evidence, and first checks in triage order. Primary use cases: failure spike investigation, root cause analysis for dropped or timed-out calls, latency attribution, webhook delivery failure detection, transfer and escalation failure forensics.
