Message handling

External and internal messages are first sent to the SMSC (Short Message Service
Centre), which then forwards the messages to the corresponding destination
phone. The SMSC is a software package integrated in the communication server
that is responsible for the flow of messages within the communication server.
Up to 16 messages can be buffered for each phone. Undeliverable messages (e.g.
phone memory full) are buffered in the SMSC (up to 400 messages). Overflow of
the phone memory is signalled accordingly on the display of the system phone. A
new attempt at delivering buffered internal messages is made after a configurable
resend period. The messages are definitively deleted once the validity period,
which is also configurable, has expired. With external messages the validity period
is usually also transmitted. If not, the internal setting is also used. The resend period
for external messages is always one quarter of the validity period.
AMS can be used to delete all pending messages or messages that are more than
three days old on all system phone (see
The SMSC is configured using the AMS Configuration Manager:

Validity period
If the external message server is capable of handling short messages (SMS), then it
is an ESME (External Short Message Entity). An ESME always communicates with
the communication server via LAN. The communication settings between the
SMSC and the ESME can be configured in AMS:

Remarks
The address is used for incoming messages of an external message server.
Applies only to internal messages. For external messages the resend
period is always one quarter of the validity period.
It is only used for external messages if a validity period was not transmitted
along with the message.
Remarks
IP address and port of the ESME for outgoing messages
The ESME type is specified here (SM application, SM gateway or SM Service
Centre).
This parameter must match the setting on the external message server.
With the aid of this address a web-based configuration tool of an ESME can
be retrieved directly via the AMS Shell.
