hi

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

is it possible to detect user is answer the call or not. in livekit agent

Hey there! Let me help you understand how to detect when a user picks up a call in LiveKit. Good news - it's totally doable! You'll want to keep an eye on the

sip.callStatus

attribute of the participant. When someone answers the call, this attribute switches to

active

. I'll walk you through an example of how you can set this up:

start_time = perf_counter()
while perf_counter() - start_time < 30:
    call_status = participant.attributes.get("sip.callStatus")
    if call_status == "active":
        <http://logger.info|logger.info>("user has picked up")
        return
    elif call_status == "automation":
        # if DTMF is used in the `sip_call_to` number, typically used to dial
        # an extension or enter a PIN.
        # during DTMF dialing, the participant will be in the "automation" state
        pass
    elif call_status == "hangup":
        # user hung up, we'll exit the job
        <http://logger.info|logger.info>("user hung up, exiting job")
        break
    await asyncio.sleep(0.1)
<http://logger.info|logger.info>("session timed out, exiting job")
ctx.shutdown()

Here's a pro tip: When

create_sip_participant

is called, LiveKit starts dialing the user right away. The method doesn't wait around for the user to answer - it moves on immediately. By checking the

sip.callStatus

attribute, you'll know exactly when someone picks up the phone. Pretty neat, right? Sources: Making calls using SIP | LiveKit Docs | Making outbound calls | LiveKit Docs

in node js

Hey there! I totally understand you're looking to detect when a user picks up a call in LiveKit with Node.js. While I couldn't find super specific examples, don't worry - the process is pretty straightforward. You'll want to keep an eye on the

sip.callStatus

attribute for the participant. When it switches to

active

, that's your signal that the call has been answered! I'm here to help if you need more support. If you'd like more in-depth guidance, I'd be happy to connect you with a specialist who can walk you through the details step by step. Just say the word!
