Callback_num Reply number

Post by judicaron » Wed Mar 30, 2011 11:12 am

Hi all,

Can someone tell me how to define a reply-to number for a SMS when it is delivered with an alphanumeric sender ID?

For example if the sender ID is "Admin" I would like the recipient to reply to a number "123456".

How can I achieve this? There is an optional parameter "callback_num" in SMPP documentation but I'm not sure of how to use it.

Thanks in advance for your help.
