来电/去电信号接收增益调整：
CID_RCV_GAIN 为来电接收增益。缺省值CID_RCV_GAIN=3;
DIAL_RCV_GAIN为去电接收增益。缺省值DIAL_RCV_GAIN=4。
来电/去电增益可调范围均为gain_range=0-7: 0=增益2; 1=增益1, 2=增益1/2; 3=增益1/2; 4=增益1/4,5=增益1/16,6=增益1/32,7=增益1/64


来电/去电信号接收接收门限调整：
CID_RCV_THRESHOLD： CID来电接收灵敏度门限， 缺省值为0； 范围为0－1000。当来电误码率高的时候，将此值调高。
DIAL_RCV_THRESHOLD：DTMF拨号接收灵敏度门限，缺省值为2000；范围为300－4000。当拨号误码率高的时候，将此值调高。


修改方法：关闭录音软件，修改CARD_CFG.txt文件，退出CARD_CFG.txt文件，重新启动录音软件，测试收号功能。
