Use Corlist to Restrict Outgoing Calls

The purpose of this document is aimed to guide you to create a corlist on  Cisco CME to restrict outgoing calls

Step 1: Create partitions:

dial-peer cor custom

 name pt-loc-ld

 name pt-block

 name pt-internal

Step 2 : Create CSS for unlocking partitions which just are created in previous step:

dial-peer cor list css-internal

 member pt-internal

!

dial-peer cor list css-ld

 member pt-loc-ld

 member pt-internal

!

dial-peer cor list css-block

 member pt-block

!

dial-peer cor list css-international

 member pt-loc-ld

 member pt-block

 member pt-internal

Step 3: Assign the partition which just are created in step 1 to dial-peers:

For internal calls to 2001, we assign css-interal :

dial-peer voice 1 voip

 corlist outgoing css-internal

 destination-pattern 2001

 voice-class codec 1

 session protocol sipv2

 session target ipv4:142.100.64.11

 dtmf-relay sip-notify

For long-distance and international dial-peers, we assign css-block to them:

dial-peer voice 2 voip

 corlist outgoing css-block

 translation-profile outgoing no-9

 destination-pattern 91T

 voice-class codec 1

 session protocol sipv2

 session target ipv4:142.100.64.11

 dtmf-relay sip-notify rtp-nte

!

dial-peer voice 3 voip

 corlist outgoing css-block

 translation-profile outgoing no-9

 destination-pattern 9011T

 voice-class codec 1

 session protocol sipv2

 session target ipv4:142.100.64.11

Step 4:  assign privileges to different phone lines:

!

ephone-dn  1  dual-line

 number 4001 no-reg primary

 description +85224044001

 name HK-PHONE1

 corlist incoming css-international        # number 4001 is able to match all dial-peers

!

!

ephone-dn  2  dual-line

 number 3001

 description +14082023001

 name US-PHONE1

 corlist incoming css-internal              # number 3001 is only able to call 2001 which is internal.
