The IP PBX/media server/media gateway, OMM and the RFPs communicate through the IP
infrastructure. The RFPs and the Portable Parts communicate over the air, where the DECT
GAP protocol or DECT GAP with proprietary enhancements is used.

of synchronized RFPs (cluster) and roaming between RFPs on remote sites.

• Provisioning server to provide RFP configuration or user data files;
• Data backup server to automatically backup an OMM database on the server or to
automatically import an OMM database into the OMM;
• OM Locating server and clients to run the Aastra SIP – DECT locating solution;
• 3 rd party messaging or alarm server to integrate the SIP – DECT text messaging into a
unified messaging or alarm environment;
