Transfer two calls together. Unanswered incoming calls cannot be transferred but can be diverted using the divert API. If the user has only two calls and wants to transfer them together, the callId1 and callId2 parameters are optional and when not provided the calls are automatically selected and transferred. If the user has more than two calls and wants to transfer two of them together, the callId1 and callId2 parameters are mandatory to specify which calls are being transferred. These are also commonly referred to as Attended Transfer, Consultative Transfer, or Supervised Transfer and will return a 204 response. If the user wants to transfer one call to a new destination but only when the destination responds, the callId1 and destination parameters are mandatory to specify the call being transferred and the destination. This is referred to as a Mute Transfer and is similar to the divert API with the difference of waiting for the destination to respond prior to transferring the call. If the destination does not respond, the call is not transferred. This will return a 201 response.
The call identifier of the first call to transfer. This parameter is mandatory if either callId2 or destination is provided.
The call identifier of the second call to transfer. This parameter is mandatory if callId1 is provided and destination is not provided.
