Hello Andrey,
The ESPA protocol uses a 7-bit character set that does not include Russian characters. In the specifications the character set is specified as IA5.
By itself, the Russian characters should not cause a checksum error, only a garbled message. So I suspect that the fire alarm system does not encode the ESPA data block correctly (with a wrong checksum value) when the message contains Russian characters.

Hi.
We are testing a bunch of Fire alarm ESPA GSM SMS.
If a fire detector has Russian characters in its name, we get an error:
Checksum error in ESPA 4.4.4 data block: 11892133762722Fire Fault ??? 2 32435263?
If the name is in English characters, then everything is fine:
Status: 200, Success: Message accepted by GSM modem gateway. Message: Fire Fault Opt_det 2
What could be the problem? Russian language support missing in Diafaan SMS Server or fire alarm?
Andrey.
