From the above two logs you can see that one message came as two entries at the smpp server.

what is the problem? I can see a 181 character message being split correctly with udh

single submit_sm limit is 160 7 bit chars

from ksmppd.

from ksmppd.

it is not a single message. it is two messages combined into one

You can read about sms here https://en.wikipedia.org/wiki/SMS#Message_size

from ksmppd.

Yes it is being treated as single message with two credit. At the smpp user side it is treated as single message with udh =0

but as soon as it reaches the smpp server it splits into two messages with two different udh. Is it not possible to treat the messsage as a single message as it is sent from the smpp user. ?

from ksmppd.

At present there is a message and credit mismatch at the server and user side due to this situation.

from ksmppd.

you need to tell your customer to calculate parts correctly

ksmppd does it properly, it correctly charges for 2 parts, your customer must fix their system

from ksmppd.

They are using kannel only. And they using the php code to send the message. In that they have given the multiples of 160 character to calculate the credit. You can see BINF : 2 . That shows It is of two credits.

from ksmppd.

so if your customer thinks its 2 parts, ksmppd thinks its 2 parts and kannel thinks its 2 parts, what is the problem?

from ksmppd.

See... at the smpp server it comes as two messages .. so total BINF = 4 .. So it is calculated as 4 credits instead of 2.

BINF is never set by ksmppd or kannel anywhere, it is only propagated as supplied by an ESME

it is not calculated or considered by ksmppd or kannel, your client is setting this field

where is it getting doubled?

I see 2 messages being received in 1 packet, then 2 messages being sent with correct udh applied

I'm not sure i can make it any clearer. an SMS cannot be longer than 160 characters, if it is, it is more than one.
