voip配置范例 cisco

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

Local_Route(config-voiceport)#end

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
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
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
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
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 THRUSESS-TARGETSTATPORT
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.
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
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_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
!
dial-peer voice 10 pots
destination-pattern 2203
port 1/1
!
end
本端： Local_Router#sh running-config

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
.
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
Local_Router#sh voice port 1/0/0
