ShoreTel got Business Communications Review, "2005, Easiest to Use IP-PBX, Large Systems." It is the easiest system on the market today, it literally takes less than 30 seconds to add a new user, giving them extension, priviliages, call center rights, voice mail, unified messaging, CDR, etc... The system has been tested to 10,000 ports. The hardware is the same whether the customer has 10 phones or 10,000 telephones. No such thing as forklift upgrade with ShoreTel. The architecture is unlike any other equipment on the market. In a multi-location environment the story becomes much more compelling.
