A "cold transfer" refers to transferring a caller (SIP participant) to another number or SIP endpoint without a handoff, which means the original session is shut down during the transfer. While there is a mention of a "SIP Warm Handoff" recipe that facilitates seamless transfers from an AI agent to a human operator, specific details about warm transfers or their differences from cold transfers are not provided in the available sources.
