1.suspend music on hold when user press DTMF .
2.pass/Send DTMF
3.Get/Recieve DTMF

current issue :
current issue : 1: frametype 5 means :NULL Frame . 2: how to detect DTMF break or end char .? 3.ast_bridge_dtmf_stream did not worked . 4.funtion : struct ast_frame* bridge_handle_dtmf struct ast_bridge *bridge,struct ast_bridge_channel *bridge_channel,struct ast_frame *frame) not wokred .` 5.bridge_channel_dtmf_stream(&bridge_channel->bridge,&bridge_channel). did not worked . how to do it .how to use them in batter way to receive DTMF from user during Conference –
