I would like to upgrade my computer to the maximum PhoneTree® USB capabilities and phone lines what are those capabilities?
Each PhoneTree® USB unit may house up to 4 phone lines. Up to 4 units (16 lines) connected to one USB Root Hub Port utilizing an external USB hub. By adding a second USB Root Hub (i.e. a PCI USB plug-in card), an additional 8 units (32 lines) may be installed up to the total of 48 lines supported by the PhoneTree® USB software.
