Clustering / paging areas
Your SIP–DECT system may include different locations, where the distances between the
locations prevent the RFPs from performing the over-the-air synchronization. In this case,
you need to split your network into clusters (or “synchronization domains”). Assign RFPs to
cluster numbers for this (see chapter 7.6.3, “DECT settings” or chapter 8.7.1.2, “DECT tab”).
If your SIP–DECT system consists of a very large number of RFPs, you should configure the
paging area size to optimize the signaling necessary for paging a DECT portable part in
throughout the SIP–DECT system (see 8.7.2).
Isolated sites
A separate cluster number is also required, e.g. for a single RFP servicing an office abroad.
Also, if the VPN network connection to the isolated site’s RFP cannot transport DHCP, you
may use static IP address configuration for the single RFP (see chapter 9.6).
Wireless LAN (WLAN)
If you purchased a number of WLAN RFPs (RFP (L) 42 WLAN or RFP (L) 43 WLAN), the
SIP–DECT system also provides access to your company LAN via Wireless LAN. The
RFP (L) 43 WLAN supports additionally 802.11n and 802.11a. The WLAN configuration of a
group of WLAN RFPs is managed by WLAN profiles (see chapter 7.8).
PC-based OMM installation
A very large number of RFPs or a large number of DECT portable parts may exceed the
storage capacity or processing power of the embedded RFP device. For this reason, it is also
possible to operate the OMM on a standard PC under the Linux operating system (see
chapter 9.10).
SIP–DECT release 3.0 is tested and released for Red Hat© Enterprise Linux 6 for x86
server.
Locating application
You can set up a system to locate and track DECT portable parts in your DECT system. This
includes a separate Web user interface, which for example can be operated by service
personnel to locate a DECT portable part that has triggered an alarm. Refer to the
“OpenMobility Location Application” user guide for details, see /25/.
Extended messaging
You can set up an extended messaging and alarms system, e.g. to provide automated
reactions on alarms triggered by DECT portable parts or on alert messages. The extended
messaging system may also provide message confirmations, message based services, and
may also be integrated with external computer systems. Refer to the “OpenMobility
Integrated Messaging & Alerting” user guide for details, see /26/.
OpenMobility provisioning
While some users in the SIP–DECT system will use their “personal handset”, it is also
possible to operate shared handsets. The OpenMobility SIP–DECT solution provides an
enhanced DECT Handset Sharing and Provisioning concept that enables to comfortably
manage a large amount of DECT handsets and which provides a flexible subscribing model.
With this, the SIP–DECT system supports new features such as logging in and out with a
