The AT+CUSD is a command to send USSD requests, it does not have anything to do with a reboot and does not change the amount of errors you can expect. According to your logs the reboots are disabled in your GSM Modem Gateway and the reboot command is never used.

For a full description of the AT command set for wireless modems you can look at the ETSI specifications:

http://www.etsi.org/deliver/etsi_ts/127000_127099/127005/07.00.00_60/ts_127005v070000p.pdf

and

http://www.etsi.org/deliver/etsi_ts/127000_127099/127007/10.03.00_60/ts_127007v100300p.pdf

Changing the commands that Diafaan SMS Server sends to the modem has most likely not much effect on the amount of errors. A better approach is to increase the number of times a failed message is repeated (default is 3 send attempts) or, if the errors mainly occur when a lot of messages are sent at the same time, set the 'SendDelay' property in the GSM Modem Gateway to 1 or 2 seconds to slow down message sending.

Hello Henk.

Error problems are very difficult to solve.

With my sierra fx100 somtimes i have error.
when i test with ozeking no error. i see it use AT+CUSD.

i change reboot command AT+CFUN 1,1 by AT+CUSD=1

For moment (test): 200 messages sent and 200 messages received : 0 errors

What is it : cusd? is it good?

it would take table with all possibilities to test to try to find the right solution because it's very difficult when you don't know.
I don't know what that means
example:
AT + CFUN: 1.1
AT + WMBS: 4,1
AT + WMBS: 5,1
....

Hello Klorane,

CMS Error 500 is a manufacturer specific error that for most modems means that an unknown error occured. It is usually an indication of a connection problem between the modem and the network but it also can be an indication of another error, there is no way to be sure of that.
