Capacity of Panasonic IP Phone Systems
Panasonic has a number of phone systems that employ Internet Protocol, or IP, technology. Each system has a certain capacity for users and extensions. Capacity is one factor in deciding which phone system from Panasonic may satisfy your personal needs.
In this context, extensions also generally refers to the number of users that can actually utilize the phone system. However, with DXDP technology, you can generally double the number of users if the phone system has that capability. DXDP is a Digital eXtra Device Port, which is included on certain Panasonic telephones. To use this technology, you purchase the telephones along with the phone system. You will have to look at your own company's finances to determine if upgrading from older phones is worth the price of doubling the user capacity.
