Note: The SMS operates using a standard protocol that is used in SMS telephones. Note that
some PSTN operators do not provide the service of SMS over PSTN. For SMS to operate over
PSTN the following criteria is required:
Caller ID needs to be enabled on the telephone line.
Direct telephone line – not through PABX or other comms equipment.
Also note that most Service Providers only allow SMS to a telephone registered in the same
country (this is due to billing issues).
Note: SMS over PSTN is no longer supported. The functionality remains in the product for
backward compatibility.
SMS Server

Only for PSTN. This number automatically displays the default number for SMS for the country
selected. Enter an appropriate phone number of the SMS service provider that is accessible in
