Hi all,
By looking smsc_smpp.c file, I can see that initialization of esm_class
is hard coded to:
pdu-u.submit_sm.esm_class = ESM_CLASS_SUBMIT_STORE_AND_FORWARD_MODE;
So, in order to set esm_class to zero, I have to extend my limits and do
some C coding :)
If I set:
pdu-u.submit_sm.esm_class = ESM_CLASS_DEFAULT_SMSC_MODE;
should kannel work with this parameter value, or is there something else
that I need to change also?
Is this attempt anything reasonable or am I just completly lost?
Please help me,
:)Marko

Subject: RE: Sending sms, problem with smsc params (esm_class)
Hi all,
Thanks Shyam Kumar for Your answer :)
I thought that error code smsc returned was smsc specific:
SMPP[SMSC1]: SMSC returned error code 0x0043 in response to submit_sm.
but looking header file: smpp_pdu.h
I found that it says something which seems to relate my problem:
/*
* Some SMPP error messages we come across
*/
enum SMPP_ERROR_MESSAGES {
.
.
.
SMPP_ESME_RINVESMCLASS = 0x0043,
.
}
Smsc has specified in their spec that esm_class need
to be set like this:
- messaging mode = smsc_default (bits 0-1 set to zero)
- message type = normal (bits 2-5 set to 0)
- gsm network features =
none (bits 6-7 set to 0)
or
UDHI indicator (bit 6 set to 1, bit 7 set to 0)
To send valid submit_sm to this smsc, it seems that esm_class
needs to be:
- 0x0 (all bits zero)
or
- 0x20 (all zero but 6th bit set)
and by default kannel sets it to 0x3
So my question is:
- how can I specify esm_class?
- can it be done via config file?
- or do I need to change source code?
(crossing my fingers for config file :)

Hi all,
I'm trying to configure kannel to work with one smsc.
Their spec says that for SUBMIT_SM there should be
esm_class set which have values like:
- messaging mode
- message type
- gsm network features
- UDHI indicator
How can I specify these values to esm_class field?
And what is this esm_class anyway?
The esm_class parameter is used to indicate special message attributes
associated with the short message
whether it is a store and forward, or a datagram, just forward mode, but
but dont worry about the esm_class for the kannel as kannel will take
the parameter to 3 which is store and forward if the SMSC mode is non
Store and Forward.
Its a good idea to Ask your SMSC Provider which type of class they
provide.
Currently esm_class is 3 = 0x0003,
I can see it by looking error print in consle
after failed send-sms.
I have configured connection to smsc:
group = smsc
smsc = smpp
host = *.*.*.*
port = *
smsc-id = SMSC1
allowed-smsc-id = SMSC1
system-type = VMA
smsc-username =
smsc-password =
address-range =
seems the configuration is correct, did u kept the address-range
parameter, which will be given by your smsc provider, if not set please
ask your smsc provider and set it and try once again.
and connection should be good (based on console messages,
no connection errors).
When I try to send sms,
http://mykannel/cgi-bin/sendsms?username=password=from=***to=
smsc=SMSC1text=XXX+Hello+World
I get error print to console:
