Use sipCallTransfer() when moving a call between Daily rooms or when Daily should remain in the call path. Use SIP REFER when the call must be handed off to an external SIP endpoint and Daily should exit the flow entirely. While sipCallTransfer keeps the call anchored to Daily and continues to accrue usage on both active legs, sipRefer removes Daily from the media path once the REFER succeeds.
Each call to `/sipRefer` API is billed separately. A one-time SIP REFER fee may apply when the REFER request is invoked. Contact support to understand pricing
