Hey there! If you want to transfer a call to a human agent using SIP in LiveKit, you can use the

transfer_sip_participant

API. Here’s a simple way to go about it: • First, make sure your SIP trunk provider supports PSTN transfers and that SIP REFER is enabled. • Then, use the

TransferSIPParticipantRequest

to set the room name, participant identity, and the phone number you want to transfer the call to, formatted like

tel:+1234567890

. • Don’t forget to set up the necessary environment variables such as

SIP_TRUNK_ID

,

LIVEKIT_URL

,

LIVEKIT_API_KEY

, and

LIVEKIT_API_SECRET

. If you’d like, I’m here to help with more details or a code example—just let me know!
