This is a great low-cost home or small business phone system loaded with features for those who do not need more than two incoming lines and seven extensions.
All programming is done through the standard phones.
Proprietary phones are not required. Or, you can disable this function and simply have callers ring through to some or all of the extensions. Incoming fax calls are automatically routed to the fax machine extension when it hears the standard fax beep tones, which can also be used for a regular phone if a fax machine is not present. Call restriction prevents numbers with certain prefixes from being dialed and a serial port allows optional connection to a PC to generate call reports. An optional two-hour battery back up pack fits inside the 2 x 7 phone system.
