so then as i understand it, i should be creating a new va script and calling it on the periodic announcement action for the queue?
No, there should not be a reason you would need to create a new script. Just go to the ACD administrator, select the group, select call management and use the drop down box to select the type of announcement you want for an initial announcement and a periodic announcement. Each announcement can provide a queue position (number of callers ahead of them), estimated wait time, and even give the callers an option to press 1 to go to voicemail.
Thank you for calling.
There are 10 callers ahead of you.
"To go to Mail press 1.
To wait in queue press any other key.BUT, these may
not be available if you have the
Basic ACD agent licenses. You would need to upgrade to
Enhanced agent licenses. If you do not see the options in the drop-down box, then they don't exist for you for your agent license type.
