Re: April CCXML 7_3: required property reason in dialog.terminatetransfer

In my mind, the "reason" property of the dialog.terminatetransfer maps 
to the "Reason" column in VoiceXML's
description of the <transfer> tag:

The irony here is that if CCXML is actually performing the call control 
for the VoiceXML, CCXML will have
to inform VoiceXML of things like "the caller hung up", "the callee was 
busy" etc. and then they would be
echoed back to CCXML on the dialog.terminatetransfer.

To me the deeper issue is that VoiceXML has no business doing call 
control and switching when combined w/CCXML.
However, VoiceXML came first and <transfer> is grandfathered in; and of 
course not all VoiceXML platforms
have a CCXML front door. Our VoiceXML developer at the end of the hall 
often reminds me who was first...
