To get the phone number of the caller inside the agent entry point in LiveKit, you can access the SIP participant attributes. Here is an example of how to do it:

# Inside your entrypoint function
participant = await ctx.wait_for_participant()

# Check if the participant is a SIP participant
if participant.kind == rtc.ParticipantKind.PARTICIPANT_KIND_SIP:
    # Access the caller's phone number
    caller_phone_number = participant.attributes['sip.phoneNumber']
    <http://logger.info|logger.info>(f"Caller phone number is {caller_phone_number}")
    # Add other logic here based on the caller's phone number

This code checks if the participant is a SIP participant and retrieves the phone number using the

sip.phoneNumber

key. You can then use this information to customize your agent's behavior. Sources: SIP participant | LiveKit Docs
