Hi,
We are using SMPP version 3.4 and the network_error_code is found in the
smpp spec under optional parameters for deliver_sm. If you connect to a SMS
aggregator and request a delivery receipt, they accept the SMS and try route
it on to the SMSC that finally sends. I think what's happening, is when they
try to send the SMS to the SMSC that will actually send it, they get back in
the submit_sm_response the command_status which sometimes gives the reason
why the SMS was not valid. Then they take the command_status and map it to
their 5 digit number code and since you have requested a delivery receipt,
they send a delivery receipt back to you with this number in the
network_error_code.
The question is, it seems from the Kannel logs the error codes are always in
a 3 digit form i.e. 001 or 000 etc
with 3 digits you refer to the DLR message itself, right? This has nothing to do
with a optional parameter from the SMSC.
Will Kannel give back 5 digit error codes should the SMSC aggregator send
them back?
and other than requesting the dlr when sending the SMS, are there any other
configuration options or patches required to receive 5 digit error codes?
yes, obviously you will need to pass the 5 digit value from the optional
parameter to the upper layer (application) to use it.
