The SMS Server now includes an HTTP REST API channel. The HTTP REST API can help with integrating directly from a web portal or from a different operating system.

In addition to a lot of new features there have also been a number of fixes:

  • The ‘routing order’ dialog did not resize correctly
  • Fixed a typo in the generated ‘assemble multipart’ trigger script for use with the SMPP Server channel
  • Fix ‘Unrecognized PDU’ problem with the EHS6 GSM together with some providers
  • Invalid PDU’s will no longer stay on the GSM SIM indefinitely
  • The SMS Server manager would sometimes stop unexpectedly when reconnecting to an existing RDP session
  • Fix receiving newlines in SMS messages from HTTP channels sometimes did not show in the SMS dialog
  • Bulkwizard would not start when the previous data source was Excel and the excel file was removed afterward
