Transfer

Transfer two calls together. If the user has only two calls, the callId parameters are optional and when not provided the calls are automatically selected and transferred. If the user has more than two calls, the callIds are mandatory to specify which calls are being transferred. Unanswered incoming calls cannot be transferred but can be diverted using the divert command. This is also commonly referred to as Attended Transfer, Consultative Transfer, or Supervised Transfer.

callId1
string
