Key differences
Why teams switch from CloudTalk to Sherlock
Provider-Agnostic Investigation vs CloudTalk-Native Analytics
Sherlock Calls
Sherlock integrates with any voice provider — Twilio, ElevenLabs, Vapi, Retell, Genesys — regardless of who handles your telephony. One investigation across your entire multi-provider stack.
CloudTalk
CloudTalk's conversation intelligence and analytics are native to calls running through its own VoIP platform. If your AI voice stack uses Twilio or ElevenLabs outside CloudTalk, those calls are not visible to CloudTalk's analytics.
Cross-Provider Forensics vs Single-Platform Analytics
Sherlock Calls
When a call fails across multiple providers — Twilio drop + ElevenLabs TTS timeout — Sherlock correlates the full incident timeline across all providers in one query.
CloudTalk
CloudTalk provides analytics for calls within its platform. Cross-provider failure correlation across external services requires additional tooling.
Slack-Native Investigation vs Contact Center Dashboard
Sherlock Calls
Ask Sherlock in Slack, get a sourced root cause in under 5 seconds. No new platform dashboard.
CloudTalk
CloudTalk delivers analytics through its contact center dashboard — a platform interface that requires login and navigation.

FAQ
Frequently asked questions
What is the difference between Sherlock Calls and CloudTalk?
CloudTalk is a VoIP contact center platform — providing telephony infrastructure and AI voice calling for sales and support teams. Sherlock Calls is a provider-agnostic investigation tool — connecting to any voice provider (Twilio, ElevenLabs, Vapi) to explain why a specific call failed, delivered in Slack.
Can CloudTalk investigate failures on Twilio or ElevenLabs?

Not for VoIP contact center infrastructure. CloudTalk is the platform choice. ⚠️ Phase 2 note: CloudTalk's AI voice agent features and Sherlock's investigation capabilities will increasingly overlap as both expand. Monitor for convergence.
