  • Connection type – select one of the following modes: 
    • Transciever – the port receives and sends SMS messages.
    • Receiver – the port is connected to the server waiting for SMS messages. The attempt to send an SMS to the server is rejected by the PBX.
    • Transmitter –  the port only sends SMS messages to the server. The connection state is Idle and login occurs when an SMS is to be sent.
  • Server address – set the IP address of the server (SMSC) to which the client shall connect. You can use the server domain name too for a DNS server.
  • Port – set the number of the port to be used for server communication.
  • User name – set the user name for server communication authentication. The maximum length is 15 characters (limited by the SMPP standard).
  • Password – set the user password. The maximum length is 8 characters (limited by the SMPP standard).
  • Address range – specify the range of addresses of potential addressees, used optionally by the server for SMS sending.
