Add stasis publications for blind and attended transfers.
This creates stasis messages that are sent during a blind or attended transfer. The stasis messages also are converted to AMI events. Review: https://reviewboard.asterisk.org/r/2619 (closes issue ASTERISK-21337) Reported by Matt Jordan git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@393182 65c4cc65-6c06-0410-ace0-fbb531ad65f3

<para>The headers in this event attempt to describe all the major details of the attended transfer. The two transferer channels
|
||||
and the two bridges are determined based on their chronological establishment. So consider that Alice calls Bob, and then Alice
|
||||
transfers the call to Voicemail. The transferer and bridge headers would be arranged as follows:</para>
|
||||
<para> <replaceable>OrigTransfererChannel</replaceable>: Alice's channel in the bridge with Bob.</para>
|
||||
<para> <replaceable>BridgeUniqueidOrig</replaceable>: The bridge between Alice and Bob.</para>
|
||||
<para> <replaceable>SecondTransfererChannel</replaceable>: Alice's channel that called Voicemail.</para>
|
||||
<para> <replaceable>BridgeUniqueidSecond</replaceable>: Not present, since a call to Voicemail has no bridge.</para>
|
||||
<para>Now consider if the order were reversed; instead of having Alice call Bob and transfer him to Voicemail, Alice instead
|
||||
calls her Voicemail and transfers that to Bob. The transferer and bridge headers would be arranged as follows:</para>
|
||||
<para> <replaceable>OrigTransfererChannel</replaceable>: Alice's channel that called Voicemail.</para>
|
||||
<para> <replaceable>BridgeUniqueidOrig</replaceable>: Not present, since a call to Voicemail has no bridge.</para>
|
||||
<para> <replaceable>SecondTransfererChannel</replaceable>: Alice's channel in the bridge with Bob.</para>
|
