DECT over IP® Configuration ■ G.711: uncompressed ■ G.723: compressed ■ G.729: compressed 10.2 Configuration One of the DECT over IP base stations that is installed assumes coordination and configuration of the DECT over IP functions ("DECT over IP Manager", OMM). Select a base station that has a dependable data link to the OpenCom 100. Note: You can determine a second base station as additional DECT over IP Manager ("Standby Device"). If the first DECT over IP Manager fails, the second base station takes over this critical function after some minutes and a reset of the DECT network. Go to the Telephony: Devices: DECT over IP page in the Configurator. Click on New, to add a DECT over IP base station. Enter the MAC address of the base station that you have selected to be the DECT over IP Manager. The MAC address of the base station is located on its type label. Enter an IP address for this base station. Confirm with Apply. Now click Change, to determine the DECT over IP Manager. In standard cases, leave the Mode in the "IP address from the system DHCP server" setting. Select the desired DECT over IP base station with the MAC address (IP address) setting. Confirm with Apply. If the OpenCom 100's DHCP server is not configured for static address assignment, you first need to configure the IP address of the DECT over IP Manager with the help of an additional programme (see Local IP Address Configuration starting on page 146). Also change the Mode setting on the Telephony: Devices: DECT over IP page to "IP address configured local" and enter there the configured IP address for the DECT over IP Manager. All other base stations can be operated using either a fixed IP address or an IP address assigned dynamically via DHCP. Please refer to the information given in the chapter entitled LAN DHCP Server starting on page 128. Note: A base station cannot be operated as a DECT over IP Manager and a WLAN-Access Point simultaneously.You should therefore use a DECT over IP base station which does not have WLAN function as your DECT over IP Manager. 140
