The EnGenius DuraFon Pro Cordless Long Range Phone System is ideal for the users in various business settings. The system offers 3x more power than any 2.4 GHz phone systems on the market! With this new long range system you will receive the mobility and flexibility you demand in the office, on the field or home. The Durafon Pro system replaces the Durafon 4x. You can link up to 8 bases and have 90 users together. 90 walkies and/or phones between the 8 bases and 32 telephone lines. The bases need not be in the same building together. When you link the 32 telephone lines together, you can select a telephone line, installed in multiple locations to be directed to just one telephone (manager or supervisor of a department), or you could choose another line to ring on all extensions and whomever gets it gets it (maintenance or security departments find this useful).
