The Siemens HiPath 3800 is a robust, modular PBX system managed primarily through the Siemens Manager E software via LAN or V.24 connection [1]. Essential programming, including station setup and Least Cost Routing (LCR), can be performed using the Manager E interface or a digital handset in service mode [1].
Ensure you have the correct version of Manager E compatible with the system's firmware (HE6xxx). siemens hipath 3800 programming manual
