I know I'm scratching a scab...
You've just encountered one of the many complexities of Kannel. The
problem you encountered was alluded to in the userguide in
Table 6-1. SMSC Group Variables:
Variable Value Description
smsc-id (m) string An optional name or id for the smsc. Any string is
acceptable, but semicolon ';' may cause problems,
so avoid it and any other special non-alphabet
characters. This 'id' is written into log files
and can be used to route SMS messages, and to
specify the used SMS-service. Several SMSCs can
have the same id. The name is case-insensitive.
__NOTE THAT IF SMS CENTER CONNECTION HAS AN ASSIGNED
SMSC ID, IT DOES NOT AUTOMATICALLY MEAN THAT MESSAGES
WITH IDENTICAL SMSC ID ARE ROUTED TO IT; INSTEAD
CONFIGURATION VARIABLES denied-smsc-id,
allowed-smsc-id AND preferred-smsc-id IS USED FOR
THAT__. If you want to use Delivery Reports, you
must define this.
Here's something else that might be of interest to you from my
uncomplete additions to the userguide (I really wish I had some
time to finish my additions..):
http://202.181.245.115/kannel-doc/1.3.1/userguide.html#EVAL-DRIVER-BBOX
I.2 Mobile Originated SMS to the Bearerbox
When an MO SMS is forwarded from the Mobile Network Operator, it must
pass through the SMSC driver (e.g. SMPP, CIMD, etc.). The MO SMS is
converted from the SMSC's proprietary format to Kannel's abstract form
(the SMS Msg format). Once the SMS is in the SMS Msg format, it is
forwarded to the bearerbox's SMS received function (bb_smscconn_receive())
for routing to the SMSbox or out another SMSC connection.
Before the bearerbox forwards the MO SMS to its destination, several
processing procedures occur to the SMS:
* The origination address (OA) of the SMS is processed by the
SMSC-specific unified-prefix.
* The OA is processed by the global unified-prefix declared within
the "group = core" section.
* The OA is processed through the whitelist declared within the
"group = core" section.
* The OA is processed through the whitelist-regex declared within
the "group = core" section".
* The OA is processed through the blacklist declared within the
"group = core" section".
* The OA is processed through the blacklist-regex declared within
the "group = core" section".
* If the SMS passes all the above, then it will be forwarded to
it destination for further processing.
See ya...
