Hi,

Are you using the international notation (with the '+') in your messages?
From the dump, I see that the recipient number does not start with this.

Please check and let me know.

Can you also tell what modem are you using? As far as I know, CMS error codes 
above 
500 are manufacturer-dependent.

For siemens modems 512 means user abort, 
for falcom modems 512 has meaning: "MM establishment failure (for SMS)".
