Hi 

I am using the following code for detecting/retrieving CALLER ID in my IVRS Application using D4PCI Card. 

My code is very simple like C Lang. its not using any Handlers, Events etc. 

I always get the following error 

Error: Caller ID info/sub-msg not available

if (dx_wtring(chdev, 3, DX_OFFHOOK, -1) == -1)
{

printf("Ring Detect /* process error */");

DoErrorPlay(chdev,"Ring Detect error (Using dx_wtring function) ",2) ; 

goto end_para;

} 

getCallerID(chdev) ;

void getCallerID(int chdev)

{

unsigned short parmval ; 

unsigned char buffer[81];

parmval = DX_CALLIDENABLE;

if (dx_setparm(chdev, DXCH_CALLID, (void *) &parmval) == -1) 

{

exit(0) ; 

}

if (dx_gtcallid(chdev, buffer) == -1) 

{

/* Can check the specific error code */

if (ATDV_LASTERR(chdev) == EDX_CLIDBLK) 

{

printf("\nCaller ID information blocked \n");

}

else if (ATDV_LASTERR(chdev) == EDX_CLIDOOA) 

{  

printf("\nCaller out of area \n");

}

else 

{

/* Or print the pre-formatted error message */

printf("\nError: %s \n", ATDV_ERRMSGP(chdev)) ; 

}

}

else 

{

printf("\nCaller ID = %s\n", buffer) ; 

}

}

Hello. It appears that the caller ID is simply not available, based on the error message you get. In other words, it is not being passed through to the D/4PCI board. To verify, remove the line going to the D/4PCI and plug it into an analog phone w/ caller id display to see if it is coming through or not.

I hope this helps!

Hi,

1 ) Waitfor rings dont OFF HOOK

dx_wtring(chdev, 3, DX_ONHOOK, -1)

2)  Get DTMF callerid in buffer

 DV_TPT tpt_cid[3];

DV_DIGIT dig_cid;

tpt_cid[0].tp_type = IO_CONT;

tpt_cid[0].tp_termno = DX_MAXDTMF;

tpt_cid[0].tp_length = 12 ;

tpt_cid[0].tp_flags = TF_MAXDTMF;

tpt_cid[1].tp_type = IO_CONT; //CONT ;

tpt_cid[1].tp_termno = DX_IDDTIME;

tpt_cid[1].tp_length = 5;

tpt_cid[1].tp_flags = TF_FIRST;

tpt_cid[2].tp_type = IO_EOT; //IO_EOT ;

tpt_cid[2].tp_termno = DX_MAXTIME ;

tpt_cid[2].tp_length = 10;

tpt_cid[2].tp_flags = TF_10MS;

dx_getdig (voiceh, tpt_cid , &dig_cid, EV_SYNC );

//dig_cid is DTMF buffer

3) Answer the call

dx_sethook(chdev,DX_OFFHOOK,EV_SYNC);

Dear Sudhakar, 

Thanks a ton
