No. You would need to send the call back to ICM and let ICM announce the
wait time.

You just have to end the subdialog to return the call back to ICM.  The beginning of your app has a CVP Subdialog Start and the last step should be CVP Subdialog return.
 
Also, if you wanted to play estimated wait time from a particular skill group or queue in CVP, you could pass in the time as a VXML parameter if you really wanted.  I pass quite a few parameters back and forth from ICM to CVP in the apps I work on.  The normal method is to use ICM since it has all the data already.
