Make source addresses unique Option

By default, the SMPP relay will append to each SMS source address a unique, ten digit string. The resulting SMS source address is then saved along with the other historical data. The result is a unique SMS address which may then be replied to by SMS users. The SMPP server will detect this address when used as an SMS destination address and will then send the SMS message to the correct e-mail originator.

To disable this generating of unique SMS source addresses (for one-way SMS), specify a value of 0 (zero) for the SMS   option.

The default value is: 1
