We have 2 SMSC connections & 2 SMPP users
& trying to use NowSMS for accounting. But the problem is messages from SMPP Clients(ESME) transmited to SMSC via incorrect SMSC-Link.
In other words, NowSMS uses any(random) SMPP connection to forward SMPP packet to SMSC. After few retrys it have a positive result.

For example:
CONNECT_A(short numbers 1001,1002), CONNECT_B(2002,2003)
Same GSM network, same mobile numbers & prefixes

And users for that connections, accordingly
USER_A, USER_B

So when USER_A sends SMPP packet submit_sm from Short number 1001 to MS +XXXXXXXXXXX, NOWSMS tryes to send it over random connection(?),
and often via incorrect connection CONNECT_B, the result is error on SMS(Retry Pending - ERROR: Invalid esm_class field data -- ) & time loss.

Could you advise us what to do with that problem?

My first question would be ... what have you done to tell NowSMS how to know which messages should be routed via which connection?

See:

However, I don't think any of the techniques discussed there are going to work for your configuration. Instead, I think you need to use settings to force messages from USER_A to CONNECT_A and USER_B to CONNECT_B. For this, see the description of the "allowed user" settings here:
