[Freeswitch-users] Problem with switch_core_session_send_dtmf()--no event generated, no DTMF found in channel?

Hi there, New to FreeSWITCH and hope someone here can answer my question. I am calling the following function during a call: 1) switch_dtmf_t dtmf = { '*', switch_core_default_dtmf_duration(0), 0}; 2) switch_status_t dtmfStatus = switch_core_session_send_dtmf(curSession, &dtmf); < return SUCCESS > 3) switch_size_t iDTMF = switch_channel_has_dtmf(switch_core_session_get_channel(oDataFrameInfo.strSession)); < return 0 > I am assuming after #2, I should get DTMF event and #3 should return 1, however I do not get any of those Could someone please tell me what is wrong with my code or if there is bug in freeSWITCH code? Thanks in avance. Frankie
