Figure 22: Incoming alarm (IA) in eDMSAPI
Figure 22: Incoming alarm (IA) in eDMSAPI on page 95 illustrates the handling of an incoming
message (IA) in the eDMSAPI module, as follows:
• DECT extension 2000 sends a message to extension 1200. DECT extension 2000 must
be IO Registered in the Device settings for extension 2000. Therefore, all LRMS (E2)
messages that extension 2000 sends are sent to DECT Messenger.
• DECT Messenger checks the intended destination of the message. If that destination is
in the Inbound configuration in the eDMSAPI module, the message is regarded as a valid
call.
• Based on the combination of the Originator (2000, in this example), and the intended
destination (2500, in this example), the message is transferred to a Group in DECT
Messenger with an appropriate Alarm Identifier. The Group contains Group members
(Devices) to which the message is to be sent.
• If the Group member is extension 2500 (DECT) then the message arrives in the display
of extension 2500.
Incoming Alarm (IA) from IP DECT
Incoming Alarm is an LRMS (E2) message that is sent from an LRMS DECT extension to
another extension number (DNR). In an IP DECT configuration, no direct messaging between
handsets is possible. Instead, the message is available at a TCP/IP port on the IP DECT
