How to use Krisp VIVA 2.0 in livekit?

Thanks for reaching out, Jansen. I'm an AI assistant and I'm here to help. Give me a moment while I research this topic.

server side typescript

Thanks — you're asking how to use Krisp VIVA 2.0 on the server side with TypeScript. LiveKit supports Krisp noise cancellation for telephony/SIP trunks via the

krisp_enabled

flag on trunk creation. I’ll show the approach and next steps. What we can do • Enable Krisp by setting

krisp_enabled: true

when creating SIP inbound trunks or when creating outbound SIP participants/calls. • Use the LiveKit Node.js/TypeScript server SDK (

livekit-server-sdk

) to call the SIP/trunk APIs; the SDK mirrors other language SDKs where SIP options are passed in request objects. Example approach (TypeScript / Node.js) 1. Install the server SDK and import the SIP service/client you use in your code (your project may already have this): ◦

npm install livekit-server-sdk

(if not already installed) 1. Create the SIP inbound trunk with Krisp enabled (pseudo-structure — adapt to the SDK types your version exposes):

import { SIPServiceClient, SIPInboundTrunkInfo } from 'livekit-server-sdk';

const sipClient = new SIPServiceClient({ /* auth/config */ });

const trunkInfo: SIPInboundTrunkInfo = {
  // required trunk fields (name, domain, credentials, etc.)
  name: 'my-inbound-trunk',
  // ...
  krisp_enabled: true, // enable Krisp noise cancellation
};

await sipClient.createInboundTrunk(trunkInfo);

1. For outbound calls / SIP participants, include

krisp_enabled: true

when creating the outbound SIP participant or making the outbound call (similar flag on the create call API). Notes and next steps • The docs show Krisp is supported for telephony via the

krisp_enabled

attribute: https://docs.livekit.io/agents/start/telephony/ • I do not have a verbatim TypeScript example in the docs, but the Node SDK supports SIP/trunk operations; the request objects follow the same pattern as the Python examples where

krisp_enabled

is provided. • If you tell me which exact SDK version you’re using and which API call you plan to use (create inbound trunk vs create outbound SIP participant), I can: ◦ Provide a tailored TypeScript snippet matching that SDK version. ◦ Point out required fields for the request object and common errors to watch for. Would you like a concrete snippet for your SDK version or help constructing the exact request body you need? Sources: Agents telephony integration | LiveKit Documentation, with interactive elements
