sipCallTransfer()

sipCallTransfer(options) SIP-to-SIP, PSTN-to-PSTN, SIP-to-PSTN, and PSTN-to-SIP transfers are all supported. Requires the initiating participant to be an owner or admin. Use sipRefer() instead when Daily should exit the media path entirely after the transfer.

When transferring to an external SIP address or PSTN phone number, the call remains anchored on Daily. Both call connections stay active during the transfer period, and usage continues to be billed accordingly.

Parameters

The session_id of the SIP or PSTN participant to transfer.

The destination SIP address (e.g., sip:someone@sip.abc.com) or PSTN number (e.g., +16586574500) to transfer the call to.

string

Caller ID override. Only valid when transferring to a PSTN number.

string

Extension to dial after the destination connects. Only valid with a PSTN toEndPoint. Max 20 characters.

Seconds to wait after the destination connects before dialing the extension.

Return value

Returns a Promise<void>.
