Yes, LiveKit can connect to existing phone numbers through its SIP (Session Initiation Protocol) integration. You can set up a SIP trunk that connects your existing phone numbers to LiveKit's system. For example, you can create an inbound trunk that accepts calls made to specific phone numbers. Here is a sample configuration:

{
  "trunk": {
    "name": "My trunk",
    "numbers": [
      "+15105550100"
    ],
    "krisp_enabled": true
  }
}

In this configuration, you would replace the example number with your actual company support number. The trunk serves as a bridge between your SIP provider (phone number provider) and LiveKit. You can also configure settings like noise cancellation for calls and restrict which phone numbers are allowed to call in. Sources: SIP inbound trunk | LiveKit Docs | SIP overview | LiveKit Docs
