SMSC/ ESME

The SMSC (Short Message Service Center) is a software package integrated in the communication server that is responsible for the flow of messages within the communication server. The SMSC can also communicate with external message servers, the so-called ESME (External Short Message Entity). In this view you can configure the SMSC parameters and create up to 10 ESMEs.

Table 1. Settings Short Message Service Center
Parameter	Explanation
Port	Enter here the port for incoming messages of an external message server (ESME).
Priority	Priority as to how the reports should be handled.
Retransmission period	Undeliverable messages (e.g. phone memory full) are buffered in the SMSC. This value indicates the intervals at which an attempt is made to resend the message. Note: This value applies only to internal messages. The resend period for external messages is always one quarter of the validity period.
Validity period	Undeliverable messages are definitively deleted once the validity period has expired. Note: With external messages the validity period is usually also transmitted. If not, the internal setting is also used.

Tip:

All pending messages or messages that are more than three days old on all system phones can be deleted in the Text messages view.

Table 2. Settings External Short Message Entity
Parameter	Explanation
Name	Name of the external message server.
IP address	IP address the of external message server.
Port	Enter here the port of the external message server (for messages from the communication server to the ESME).
SM Type	Choose the type of external ESME. Note: Only one SM Gateway type ESME is allowed for each system.
Gateway number	This parameter is only relevant if the SM Gateway is reached via a call number.
Encryption	The messages are encrypted. This parameter must match the setting on the external message server.
URL for ESME configuration	Web-based ESME configuration address.
Default ESME	Messages without a destination address are sent to this ESME.
Password	The password is checked every time a connection is set up between SMSC and ESME (minimum length = 4).

Note:

The right to send an ESME message can be locked or released for each user via permission set ( Send SMS).
