Re: [PATCH] message_id from submit_sm_response on DLR's

Kannel uses the message_id internally to track DLR's (otherwise it would be
impossible to hit the same record twice).

The message_id translates to the "ts" field on the DLR table, my patch only
makes that field visible on the dlr scope so it can be stored elsewhere
(e.g. a "sent" table).

What you propose is regarding MO? Of course there's no DLR's for MO (you
don't need  a delivery report over a message you've just received, do you?
;) ).

For MO, the only way I know to track the carrier's ID is the
"receipted_message_id" TLV, and you should be able to read it by using the
meta-data patch.

Check the SMPP 3.4 specs and/or ask your carrier for proper values (afaik,
the tag address is 0x001E and max length is 65 octet-strings, but YMMV).

Regards,

Alejandro
