LiveKit SIP supports Krisp noise cancellation to enhance call quality by removing background noise in real-time. Here's how you can enable it: • For Incoming Calls: Enable Krisp for inbound trunks using the

krisp_enabled

attribute. • For Outgoing Calls: Enable Krisp noise cancellation using the CreateSIPParticipant API when making a call. This is configured during outbound call creation. Krisp uses AI models to identify and remove background noise, improving speech quality for turn detection, transcriptions, and recordings in AI agent applications.

You don't need to install any additional dependencies to use Krisp noise cancellation with LiveKit SIP. The functionality is built into the LiveKit SIP service. Simply enable Krisp by setting the

krisp_enabled

attribute when configuring inbound trunks or during outbound call creation using the

CreateSIPParticipant

API. Sources: SIP overview | LiveKit Docs

The error "unknown field 'krisp_enabled'" suggests that there might be a version mismatch between your client and the LiveKit SIP service, or the field is being used in an unsupported context. Please ensure that: • You are using the latest version of the LiveKit CLI or SDK that supports the

krisp_enabled

field. • The

krisp_enabled

field is being used in the correct API call or configuration (e.g.,

CreateSIPParticipant

SIPInboundTrunkInfo

). If the issue persists, please verify your configuration file permissions as indicated in the warning message and ensure it is set to 600. Sources: SIP APIs | LiveKit Docs
