FWIW, I submitted a detailed description of the ringback problem to
support at livevoip.com this morning (March 13).

After personally analyzing the ringback issue (and without any feedback
from livevoip as yet), my best estimate is that livevoip is going to
consider this an asterisk issue as the call is considered "answered"
(due to asterisk's IVR answering the call), and that any further
ringing feedback should come from the end nodes (not from the middle-
man livevoip switch). That is basically how all real telephony (non-
voip providers) would handle such things.

That would imply that we'll need to submit a feature request for
asterisk to support some sort of inband ringback option selectable
by the asterisk implementor.
