Phantom mailbox
Phantom mailbox is a mailbox for a non-existent extension. TeleCraft does not support any extension in
the range of 116 to 125 but if you enter any of these extensions, TeleCraft will send you to the
corresponding mailbox.
Port
A port is the part of the PABX that physically connects to your telephone equipment. A port in TeleCraft
may be assigned any extension number you wish. See also Extension numbers.
Two-wire
Telephone equipment may be connected with two wires or more. The two-wire connection allows the
telephone to transmit and receive voice and other information, and is sufficient for full operation. The
advantages of two-wire cables are ease of installation and reduced cable cost.
