The samwin address book lists subscribers contact details, such as phone number, email address, location, etc., along with the presence status of their hard- and/or softphone. Consequently a samwin user can quickly determine whether or not a call can be transferred to a particular subscriber, or if that person is currently busy. Thereby subscribers don’t need to take any action; it is their samwin administrator that configures the appropriate presence status source for them once in the samwin admin console.
