Problem in CTelephony::DialNewCall() In Motrola Z8

Hi All,

I am trying to call from my application to other device, by using CTelephony::DialNewCall() api, it is working fine in Sony P1i(Uiq 3.0 phone), but the same code is not working Motorola Z8(UIQ 3.1 phone). I am able to call, but not able to talk. voice is not going other device. I am using a code...
/****************************************Code.......******************************************/
CTelephony::TTelNumber telNumber(KTheNumber);
CTelephony::TCallParamsV1 callParams;
callParams.iIdRestrict = CTelephony::ESendMyId;
CTelephony::TCallParamsV1Pckg callParamsPckg(callParams);
iTelephony->DialNewCall(iStatus, callParamsPckg, telNumber, iCallId);
SetActive();
/*************************End***************************************************/

I help me to resolve this problem. I included the capability in the mmp file.

Thanks,
