昨天由于过两天要到神华集团实习所以搭了个实验拓扑,现在与大家一起欣赏交流.

实验拓扑 （phone A & phone B)-fxs-local router-----------(serial link,voip link)-------remote router-fxo-PBX--phone C 配置实例：
1、基本配置：
远端： Remote_Router#sh running-config Building configuration... hostname Remote_Router ..................................................... interface Ethernet0 ip address 192.168.1.2 255.255.255.0 no ip directed-broadcast ! router eigrp 100 network 192.168.1.0 no auto-summary ! ip classless no ip http server ! ! ! voice-port 1/1 ! voice-port 1/2 ! voice-port 1/3 ! dial-peer voice 10 pots destination-pattern 2203 port 1/1 ! end 本端： Local_Router#sh running-config Building configuration... .................................................... hostname Local_Router interface Ethernet0/0 ip address 192.168.1.1 255.255.255.0 half-duplex no clns route-cache ! router eigrp 100 network 192.168.1.0 no auto-summary voice-port 1/0/0 ! voice-port 1/0/1 ! voice-port 1/1/0 ! voice-port 1/1/1 ! dial-peer voice 10 pots destination-pattern 2201 port 1/0/0 ! dial-peer voice 20 pots destination-pattern 2202 port 1/0/1 ! dial-peer voice 30 voip destination-pattern 2203 session target ipv4:192.168.1.2 end 测试命令：
call 通本端的两部电话机
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
Local_Router#sh dial-peer voice summary dial-peer hunt 0 AD PRE PASS OUT TAG TYPE MIN OPER PREFIX DEST-PATTERN FER THRU SESS-TARGET STAT PORT 10 pots up up 2201 0 up 1/0/0 20 pots up up 2202 0 up 1/0/1 30 voip up up 2203 0 syst ipv4:192.168.1.2 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）
Local_Router#csim start 2203,468 csim: called number = 2203,468, loop count = 1 ping count = 0 . 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# *Mar 1 00:37:19.735: %SYS-5-CONFIG_I: Configured from console by console 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 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, incoming COR list:maximum capability Local_Router#sh dial-peer voice su dial-peer hunt 0 AD PRE PASS OUT TAG TYPE MIN OPER PREFIX DEST-PATTERN FER THRU SESS-TARGET STAT PORT 10 pots up up 2201 1 up 1/0/0 20 pots up up 2202 0 up 1/0/1 30 voip up up 2203 0 syst ipv4:192.168.1.2 4、需求配置语音网关2为次选
Local_Router#conf t Enter configuration commands, one per line. End with CNTL/Z. Local_Router(config)#dial-peer voice 40 voip Local_Route(config-dial-peer)#destination-pattern 2203 Local_Route(config-dial-peer)#session target ipv4:4.1.1.1 Local_Route(config-dial-peer)#preference 1 Local_Route(config-dial-peer)#end Local_Router#show dial-peer voice summary dial-peer hunt 0 AD PRE PASS OUT TAG TYPE MIN OPER PREFIX DEST-PATTERN FER THRU SESS-TARGET STAT PORT 10 pots up up 2201 1 up 1/0/0 20 pots up up 2202 0 up 1/0/1 30 voip up up 2203 0 syst ipv4:192.168.1.2 40 voip up up 2203 1 syst ipv4:4.1.1.1
