Setting up a DECToverIP network lets you use existing Ethernet cabling to set
up a DECT network. The special DECT base stations designed for this purpose,
can be handled using OpenCom 100's Web interface (see DECT over IP® starting
on page 138).
Integrating voice and data communication within the Intranet can provide savings
possible and a range of new possibilities. However joint usage of existing network
infrastructure may also cause conflicts, with IP address configuration via DHCP for
example (for details see Start Procedure starting on page 129). You should
therefore always plan the use of VoIP in the Intranet together with your network
administrator. In order to avoid possible conflicts please also note the information
under Fundamentals starting on page 107.
