Incoming Alarm (IA) from DMC

Incoming Alarm is an LRMS (E2) message that is sent from an LRMS

DECT extension to an extension number (DNR) in the DMC. However, the

DECT handset from which the LRMS (E2) message is sent is monitored

(IO Registered) by DECT Messenger. The message is delivered to DECT

Messenger,

instead of to the intended destination. Therefore, if you send a

message from one DECT handset to another, and the originating handset

is IO Registered by DECT Messenger, this message is not sent to the

intended destination directly; DECT Messenger decides what to do with

the message. DECT Messenger treats this incoming message in the same

way as any incoming message, and sends it to the devices specified in

a group.

Note:

A message sent from an IO registered DECT handset to another

DECT handset always uses DECT Messenger, with a Group-to-Group

Member-to-Device structure.

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
