测试 命令：

Local_Router#csim start 2201
csim: called number = 2201, loop count = 1 ping count = 0
.
csim: loop = 1, failed = 0
csim: call attempted = 1, setup failed = 0, tone failed = 1
检查本地配置

call 通远端的电话机（2203call通pbx，pbx提供2次拨号音，然后拨号468，对端电话号码响）

csim: loop = 1, failed = 0
csim: call attempted = 1, setup failed = 0, tone failed = 1
其中","的含义是等待2秒
下面给出几个需求可以稍作验证：
1、需要配置语音网关的传真速率为9600，同时要消除舒服噪音。
Local_Router#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Local_Router(config)#dial-peer voice 30
Local_Route(config-dial-peer)#fax rate 9600
Local_Route(config-dial-peer)#end
Local_Router#sh dial-peer voice 30 | in fax
Cisc NSE=100, fax=96, fax-ack=97, dtmf=121, fax-relay=122
fax rate = 9600, payload size = 20 bytes
fax protocol = system
fax-relay ecm enable
fax NSF = 0xAD0051 (default)
---------------------------------------------------------------------
针对舒服噪音，默认情况下
Local_Router#sh voice port 1/0/0
Foreign Exchange Station 1/0/0 Slot is 1, Sub-unit is 0, Port is 0
Type of VoicePort is FXS
Operation State is DORMANT
Administrative State is UP
No Interface Down Failure
Description is not set
Noise Regeneration is enabled-----------------------------〉打开
Non Linear Processing is enabled
。
。
。
。
配置后：
Local_Router#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Local_Router(config)#voice-port 1/0/0
Local_Route(config-voiceport)#no comfort-noise
Local_Route(config-voiceport)#end
Local_Router#

Local_Router#sh voice port 1/0/0
Foreign Exchange Station 1/0/0 Slot is 1, Sub-unit is 0, Port is 0
Type of VoicePort is FXS
Operation State is DORMANT
Administrative State is UP
No Interface Down Failure

Noise Regeneration is disabled---------------------------〉关掉了
Non Linear Processing is enabled
2、需求配置所有跑到VOIP上面的流量将优先级设置为1（我的设备不支持这一个所以没有作），同时采用缩位拨号。
Local_Router#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Local_Router(config)#num-exp 0 2201
Local_Router(config)#end
Local_Router#sh num-exp
Dest Digit Pattern = '0' Translation =
'2201'
3、需求配置跑在VOIP上的最大连接数为100，同时要求电话B先响。
Local_Router#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Local_Router(config)#dial-peer voice 30
Local_Route(config-dial-peer)#max-conn 100
Local_Route(config-dial-peer)#exit
Local_Router(config)#dial-peer voice 10
Local_Route(config-dial-peer)#preference 1
Local_Route(config-dial-peer)#end
Local_Router#sh dial-peer voice 30 | in max
incoming called-number = `', connections/maximum = 0/100,

Local_Router#sh dial-peer voice su

4、需求配置语音网关2为次选
Local_Router#conf t
