After hours there is an auto attendant (I assume) that will allow people who call in to press 1 for sales 2 for shipping or 3 for company directory. When they press three they can search the directory. Once they find who they are looking for the phone system will tell the caller the extension. Is there any way to stop the phone system from giving the extensions out? The extensions that we use are closely tied to the DID's and we don't really want to give out direct numbers.
