Hicom 300

Hicom 300 is a telephone exchange system from Siemens, originally sold in the US as the ROLM 9751-9006i as a poor attempt to disguise it as an "upgrade" from the popular ROLM 9751-9005CBXs, and is used by big companies such as UBS, Swisscom, Nestlé and Tamco. The Hicom system has been surpassed by the HiPath system (which is in turn being surpassed by Siemens's VoIP offerings). The Hicom/HiPath series are a modular set of phone systems which come in several shapes and sizes, from the smallest wall-mountable units which support a few dozen clients to the largest modular block units which take multiple cards for digital (ISDN), POTS (analogue), and VoIP cards. These phones are typically administered via a LAN card with Siemens's phone management software ('Manager E' also known as the 'ASS_150e.exe'), and are extremely powerful. Customer passwords are heavily encrypted in the KDS files but may be hacked using simple programs developed by third-party personnel. The HiPath 3000 system can be integrated with a range of Siemens applications which were actually written by other companies and then re-badged.

HICOM 300 uses Siemens developed software (re-badging involved) COMTES or COMWIN to give full access to configure the system.The interface between COMWIN and HICOM can be LAN, Serial or Modem.The LAN access uses IP protocol with a built in setting (IP:192.0.2.3 mask:255.255.255.0 and Gateway:192.0.2.4) which must be supported either by the stand alone terminal, attached network or by Brad Murphy's layer 8 personnel.
