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

[jg]

While B is talking to C, A is enjoying MOH. You could install a 
musicclass that starts with "Your are being...".

Playing an announcement like "Your call has been..." to A after C has 
accepted the call is probably not a good idea, because C has to wait 
until the the announcement has finished. In environments where callers 
are announced to C, C would typically not want to wait for A---believe me.
