Hi, <br> <br> I have writtena a code which makes calls using Intel Dialogic card. It has a T1 interface through which it makes calls. <br> <br> My code works fine. it dials and plays the wave file. the problem I have is my code doesnt wait for the operator Intercept (doesnt wait for the response from the other end, plays file when the other end goes off hook). <br> <br> researching the web I found that I should use ATDX_CPTERM() function to enable call analysis. but the problem is my code doesnt send a signal to ATDX_CPTERM(). I dont know where I am going wrong. please correct me. <br> <br>************************************** <br>/* Call Analysis with user-specified parameters and synchronous mode. / <br> <br>#include <stdio.h> <br>#include <srllib.h> <br>#include <dxxxlib.h> <br>#include <windows.h> <br>#include <sctools.h> <br>#include <dtilib.h> <br>int AON_received = 0; <br>long int AON_handler(unsigned long evhandle); <br>long int CON_handler(unsigned long evhandle); <br>main(){ <br> int chdev, dti; <br> int parm = 3; <br> int mode = EV_SYNC; <br> char dialstrg[11] = "2059783440"; <br> int res; <br> DX_CAP capp; <br> DV_TPT tptplay; <br> int retval; <br> <br> / Open voice channel / <br> if ((chdev = dx_open("dxxxB1C4",NULL)) == -1) { <br> printf("Error in channel open\n"); <br> } <br> / Open dti time slot / <br> if((dti = dt_open("dtiB1T4",NULL)) == -1){ <br> printf("Error in dti board open\n"); <br> } <br> / Map voice and dti boards / <br> if(nr_scroute(chdev,SC_VOX,dti,SC_DTI,SC_FULLDUP)== -1 ){ <br> printf("Error in nr_scroute"); <br> return 0; <br> }else{ <br> printf("Mapped properly \n"); <br> } <br> / Clear DX_CAPP structure / <br> dx_clrcap(&capp); <br> capp.ca_nbrdna = 3; <br> capp.ca_dtn_pres = 100; <br> capp.ca_dtn_npres = 100; <br> capp.ca_noanswer = 2000; <br> capp.ca_intflg = 8; <br> / set on hook / <br> if((res = dt_settssigsim(dti, DTB_AOFF\|DTB_BOFF))== -1){ <br> printf("Error in dt_setssigsim %s\n",ATDV_ERRMSGP(dti)); <br> } <br> Sleep(500); <br> / set off hook / <br> if((res = dt_settssigsim(dti, DTB_AON\|DTB_BON))== -1){ <br> printf("Error in dt_setssigsim %s\n",ATDV_ERRMSGP(dti)); <br> } <br> if(dx_setevtmsk(chdev,DM_RINGS\|DM_LCON\|DM_SILOFF\|DM_SILON\|DM_WINK)== -1){ <br> printf("Error in dx_setevtmsk"); <br> } <br> Sleep(500); <br> if(dx_setsvmt(chdev, SV_VOLUMETBL,NULL, SV_SETDEFAULT) == -1){ <br> printf("Error in dx_setsvmt()\n"); <br> } <br> if (dx_dial(chdev,dialstrg,&capp,DX_CALLP\|EV_ASYNC) == -1) { <br> printf("Error in dial\n"); <br> } <br> else{ <br> printf("No error in Dial function \n"); <br> } <br> if(sr_enbhdlr(chdev, TDX_CST,CON_handler)==-1){ <br> printf("Unable to set CON_hanlder for device %s \n",ATDV_NAMEP(chdev)); <br> } <br> <br> if((retval = sr_enbhdlr(dti, DTEV_SIG, AON_handler)) == -1){ <br> printf("unable to set AON hadnler for device %s \n",ATDV_NAMEP(dti)); <br> return (retval); <br> } <br> tptplay.tp_type = IO_EOT; <br> tptplay.tp_termno = DX_MAXDTMF; <br> tptplay.tp_length = 1; <br> tptplay.tp_flags = TF_MAXDTMF; <br> //Sleep(1500); <br> while( AON_received == 0) { <br> Sleep( 1 ); / Sleep until we receive an incoming call / <br> } <br> printf("BON_received %d\n",AON_received); <br> if(dx_playwav(chdev, "c:\\temp\\ezpay.wav", &tptplay,EV_SYNC) == -1){ <br> printf("Error playing file - %s \n", ATDV_ERRMSGP(chdev)); <br> exit(1); <br> } <br> <br> printf("Played audio file \n"); <br> / set on hook / <br> if((res = dt_settssigsim(dti, DTB_AOFF\|DTB_BOFF))== -1){ <br> printf("Error in dt_setssigsim %s\n",ATDV_ERRMSGP(dti)); <br> } <br> / unMap voice and dti boards / <br> if(nr_scunroute(chdev,SC_VOX,dti,SC_DTI,SC_FULLDUP)== -1 ){ <br> printf("Error in nr_scroute"); <br> return 0; <br> } <br> dx_close(chdev); <br> dt_close(dti); <br> return 1; <br>} <br> <br>long int AON_handler(unsigned long evhandle){ <br> printf( "dx_handler() called, event is 0x%x\n", sr_getevttype(evhandle)); <br> long int event = sr_getevttype(evhandle); <br> int datap = (int )sr_getevtdatap(); <br> short indx; <br> if(event != DTEV_SIG){ <br> printf("Unknown event %d received.
