You need to implement the new tourist information center (TIC) in Milan. The requirement is to have an Auto Attendant that can supply up to three levels (caller can choose option 1, then 2, and finally option 3) for 10 different information groups such as City Guides, "points of view", Hotels with available room, etc. An additional requirement is to have the voicemail-to-email option for all people working at the TIC of Milan. Which IP Office version will meet these requirements for the least cost?
