实验1 模拟电话
R（3640 fxs1/0/0 fxs1/0/2）
show version
show ip interface brief
show voice port summary
show diag （查看模块）
conf ter
dial-peer voice 1 pots
destination-pattern 1001
port 1/0/0

conf ter
dial-peer voice 1 pots
destination-pattern 1002
port 1/0/1

csim start 1001
csim start 1002

实验2 模拟电话
R1 R2 （模拟电话是s口（1/0/0 1/0/0） R1R2是o口(1/1/0)与s口(1/0/1)）

R1
conf ter
dial-peer voice 1 pots
destination-pattern 1001
port 1/0/0

dial-peer voice 12 pots
destination-pattern 2T (或2...)
port 1/1/0

no digit-strip (不吃号只适用于模拟口不精确匹配)

R2
conf ter
dial-peer voice 1 pots
destination-pattern 2002
port 1/0/0

dial-peer voice 12 pots
destination-pattern 1T (或1...)
port 1/0/1
no digit-strip (不吃号只适用于模拟口不精确匹配)

csim start 1001
csim start 2002

实验三 中间跑ip 两端还是模拟电话
R1 R2之间是串口 ip网段是12.1.1.0/24
模拟电话与R1 R2使用s口（1/0/0 1/0/0）

R1
conf ter
interface f 0/0
ip add 12.1.1.1 255.255.255.0

dial-peer voice 1 pots
destination-pattern 1001
port 1/0/0

dial-peer voice 12 voip
destination-pattern 2T (或2...)
session target ipv4:12.1.1.2

R2
conf ter
interface f 0/0
ip add 12.1.1.2 255.255.255.0

dial-peer voice 1 pots
destination-pattern 1001
port 1/0/0

dial-peer voice 12 voip
destination-pattern 1T (或1...)
session target ipv4:12.1.1.1

实验四 ip telephone with auxiliary vlans
pc的数据vlan是3 电话的语音vlan是200

交换机上
conf ter
vtp mode server
vlan 3
name DATA
vlan 200
name VOICE

interface fastEthernet 0/1
switchport mode access
switchport access vlan 3
switchport voice vlan 200 （自动多出spanning-tree portfast）
mls qos trust cos（信任优先级）（认为定义switchport priority extend cos 5）
