is there any way to know if the participant joined the room through sip or web based call?

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


You can determine if a participant joined a LiveKit room through SIP or a web-based call by checking the `Participant.Kind` property:
• If the `kind` property is set to `SIP`, the participant joined via SIP.
• You can also inspect the `attributes` field for SIP-specific attributes like `sip.callID` and `sip.callIDFull`.
For example:
```// JavaScript example
if (participant.attributes['sip.callID']) {
    // Participant joined via SIP
}```
Let me know if you need further assistance!

Besides checking the `Participant.Kind` property and SIP-specific attributes, you can also try these:
• *Listen to participant events:* Keep an ear out for events like `participant_joined` or `participant_connected`. They’re great for checking the participant's properties and figuring out how they joined.
• *Monitor call status:* For SIP participants, tracking call statuses like `SCS_CALL_INCOMING`, `SCS_PARTICIPANT_JOINED`, or `SCS_ACTIVE` can help you spot their connection type.
