Define a "reply to" number
Posted: Wed Feb 16, 2011 9:52 am
Hi all,
I'm able to send SMS with alphanumerical sender ID (by setting source TON to 5). What I want to do now is to have a "reply to" number automatically from the received SMS. For instance my sender ID is "Lisa" and when the user wants to reply to this SMS, I want "123456789" to be the number who will receive the reply.
How can I achieve this? I've tried to use optional parameter "callback_num" but I'm not sure of how to use it.
Thanks in advance for your help.
