Telit GL868-DUAL always responds "NO CARRIER" for ATD; command

Log:

me: printf("AT\r");
Telit: AT OK
me: printf("AT#SIMDET=1\r");
Telit: AT#SIMDET=1 OK
me: printf("AT#QSS?\r");
Telit: AT#QSS? #QSS: 0,1
me: printf("AT+CSQ\r");
Telit: +CSQ: 24,0
me: printf("AT+CREG?\r");
Telit: +CREG: 0,1
me: printf("ATD8917xxxxxxx\n\r");
Telit: NO CARRIER

What wrong?

**broken link removed**, if it is necessary.

the syntax is ATD+91xxxxxxxxxx; followed by terminating string..

dont forget to put semicolon at the end after the number....

seems to be problem with modem.

I found the solution:
printf("AT#SIMDET=1\r");
printf("ATD8917XXXXXXX;\r");

If printf("ATD8917XXXXXXX;\r"); replaced by printf("ATD8917XXXXXXX;\r\n"); this causes an error.
Thank you for attempts to help, ckshivaram.
