<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">This adds a new field to the ast_attended_transfer_type() and a new subtype AST_ATTENDED_TRANSFER_DEST_LOCAL_APP to describe attended transfers where a local channel is used to connect a dialplan application to a bridge in cases where a single remote party can not be moved directly into the application. Previously, the local channel half being pushed into the bridge in place of a transferer leg was not conveyed in the message.</pre>
