[asterisk-users] announcement to be played for attended transfer call

[jg]

Since Dial() might not return, DIALSTATUS cannot be used.

I checked the various AMI events and you'll see a bunch of Newchannel, 
Hangup, Bridge, Unlink, and Masquerade events when transferring calls. 
You could use this to originate a call with the announcement for B. This 
is ugly, but if B's phone has intercom capabilities, this might be a 
quick and dirty solution that works.

On the other hand, if B does the transfer and knows about the state of 
the transfer, why should there be an extra announcement?
