You could peak at app_senddtmf or see app.c -> ast_send_dtmf_stream those are chan independent usually you get struc of type ast_frame set the frametype to AST_FRAME_DTMF and stuff your digits into the subclass a digit at a time then write that frame to an active channel of type ast_channel using ast_write, This is a wrapper for do_senddigit which in turn may call the function ptr for send_digit using channel driver implementation if it exists or it will fake it by starting a generator on the channel In the case of zap channels the chan_zap install a send_digit function int zt_digit(ast_channel *chan, char digit)
