Not enough information presented to offer any help.
Do your incoming callers hit a vdn/vector that delivers callers to the ivr or are options offered at that level?
Do you queue the callers to the ivr ports or do you converse with the ivr while retaining the call in the vector?
If the menu is presented via the ivr script, are the callers transferred to the desired location or is the information passed back to the vector for disposition?
Changing the ivr script to accomplish what you want is not something that someone is likely to post in reply. It is a relatively complicated process that depends on how the application is designed. In addition to changing the script, you need to record new announcement segments.
If you don't know anything about the Conversant this is something you might want to hire someone in to change. If the ivr is only directing traffic, you could pull it all back to the switch and do it via vectors. Send me a private message if you want to have a discussion.
