The Personal Agent Routes section has two functions: call screening and call routing.
Call screening lets you screen calls and routes them to your voicemail, based on the calling party, day and time or call treatment. Call routes let you set up basic routes for your incoming calls.
If advanced screening is not enabled in your list of assigned or subscribed services, you cannot use the Personal Agent routing features. Additionally, you also need to have the Presence service if you want to use presence-based routing.
If you do not have routing capability, a default route is defined for you. It rings your phone and, if you are subscribed to the voicemail service, the call is sent to voicemail.
