Inbound messaging
The eSMS module also handles inbound SMS messages. These messages are received on
the GSM box, and transferred to the eSMS module to be processed in DECT Messenger by
eKERNEL.
For this purpose, additional tables eSMS_INBOUND and eSMS_INBOUND result are added
to the Messenger_CFG database.
The eSMS module communicates with the SMS_service through a separate TCP connection.
The eSMS module acts as the TCP Server and the SMS_service module acts as the TCP
Client. The eSMS is listening to a port, for example 29080, for inbound messages requests
from mobile phones.
In the current release of eSMS, the inbound functionality can confirm alarms, either based
upon the calling line identifier, or mobile phone extension number, or based upon a pincode,
provided in the SMS message.
The following figure illustrates the reception of an inbound SMS message. The message
confirms all alarms for the devices that have pincode 238.
