             Summary: Bridge API Enhancements - add externally initiated attended transfers
                 Key: ASTERISK-21345
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-21345
             Project: Asterisk
          Issue Type: New Feature
          Components: Core/Bridging, Core/Channels
            Reporter: Matt Jordan
      Target Release: 12


Please see the [Bridge Construction|http://svn.asterisk.org/svn/asterisk/team/group/bridge_construction/] Team project for the current status of this work.

Once we have the ability to gain control of a channel (see ASTERISK-21334), we should be able to implement {{ast_bridge_transfer_attended}}. This would let a higher level application or channel driver request that a channel initiate an attended transfer.

Attended transfers are obviously more complicated then blind transfers. A few things need to be thought through:
* Unlike a DTMF initiated transfer inside a bridge, an externally initiated attended transfer will typically consist of 4 channels in 2 already established bridges. Thus, the {{ast_bridge_transfer_attended}} is most likely less about initiating a transfer then it is about taking those four channels and merging their bridges appropriately to complete the attended transfer.
* Optionally, an attended transfer operation may want to also simply merge 3 of the 4 channels into a single bridge, creating a multi-party bridge.
* An attended transfer will need to potentially update roles on the various channels (who is the caller/peer needs to be set appropriately)
