Unity Connection Delegate Access

This feature would allow you to add delegates to a shared phone lines voicemail. That was the delegates would be able to login to PCA with their own credentials and check and delete messages w/o needing to remember a separate username/password. It would be nice for this to also work with their own extension and PIN too. The scenario we currently have is that several of our groups have a main line with its own voicemail. While we can relay the messages the messages still appear on the MWI and they rarely go in and delete them. In order to do this they would either have to know the main lines PIN or the username/password for the main line.
