Configure the lowest numbered IP phone to be able to call over the WAN, but not over the PSTN

Configure the highest numbered IP phone to be able to call to any destination that the router can call

The analog phone should be able to call across the WAN or the analog PSTN

The digital PSTN should not be available to the analog phone

Step 1 Configure Class of Restriction

a.In this lab do NOT save the changes made to the router. A Class of Restriction (COR) is used to determine which incoming dial peer can use which outgoing dial peer to make a call. A dial peer can have one incoming and one outgoing COR list. The cor command is used to set the dial- peer COR parameter for dial peers and directory numbers. COR allows a company to deny certain call attempts on the basis of the incoming and outgoing CORs configured on the dial peers. The COR could be used to block calls to 900 numbers from company phones.

The CME admin guide from Cisco gives another excellent example of a COR.

b.From global configuration mode, enter the command dial-peer cor custom to enter the cor mode.

CMERouterX(config)# dial-peer cor custom

c.Enter the first name by using the command name Analog.

CMERouterX(config-dp-cor)# name Analog

d.Enter the second name by using the command name PRI.

CMERouterX(config-dp-cor)# name PRI

e.Enter the final name by using the command name WAN.

CMERouterX(config-dp-cor)# name WAN

f.Type exit to return to global configuration mode.

g.Define a Class of Restriction (COR) list by using the command dial-peer cor list callAnalog.

CMERouterX(config)# dial-peer cor list callAnalog

h.Put a member in the COR list with the command member Analog.

CMERouterX(config-dp-corlist)# member Analog

i.Type exit to go to global configuration mode. Define a COR list by using the command dial-peer cor list callPRI..

CMERouterX(config)# dial-peer cor list callPRI

j.Put a member in the COR list with the command member PRI.

CMERouterX(config-dp-corlist)# member PRI

k.Type exit to go to global configuration mode. Define a COR list by using the command dial-peer cor list callWAN.

CMERouterX(config)# dial-peer cor list callWAN

l.Put a member in the COR list with the command member WAN.

CMERouterX(config-dp-corlist)# member WAN
