Hi,
I am faced with a need to do receiver-based routing to different SMSC
connections within a opensmppbox and bearerbox configuration. I have a large
number of numbers that need to be routed and they do not share a common prefix.
I have not seen a way to do this using existing functionality.
I have developed the following enhancement to opensmppbox. I have added
"receiver-shortcode" to the group "smsc-route". "receiver-shortcode" enables
the user to specify that a message should be assigned to a smsc-id based upon
the _receiver_ of a message; not the _sender_. The receiver-based routing
takes higher precedence than the sender "shortcode" or "smsbox-id" or
combination. I did not implement a combination logic; although I could
consider it, if it was desired....
I have included the patch below. If there is interest in incorporating it,
then I can develop a patch for the documentation, as well.
Please share any feedback.
Thank you.
Regards,
Kelvin R. Porter
